# Creating a Basic Grid

Learn how to create and configure an AG Grid instance from scratch. This guide introduces the essential concepts required to build an interactive grid, including setting up row data, defining columns, applying grid options, formatting cell values, and adding custom components.

## Overview

In this tutorial you will:

1. [Create a basic grid](https://www.ag-grid.com/javascript-data-grid/deep-dive/#create-a-basic-grid)
2. [Load external data into the grid](https://www.ag-grid.com/javascript-data-grid/deep-dive/#load-new-data)
3. [Configure columns](https://www.ag-grid.com/javascript-data-grid/deep-dive/#configure-columns)
4. [Configure grid features](https://www.ag-grid.com/javascript-data-grid/deep-dive/#configure-the-grid)
5. [Format cell values](https://www.ag-grid.com/javascript-data-grid/deep-dive/#format-cell-values)
6. [Add custom components to cells](https://www.ag-grid.com/javascript-data-grid/deep-dive/#custom-cell-components)
7. [Hook into grid events](https://www.ag-grid.com/javascript-data-grid/deep-dive/#handle-grid-events)

Once complete, you'll have an interactive grid, with custom components and formatted data - Try it out for yourself by **sorting**, **filtering**, **resizing**, **selecting**, or **editing** data in the grid:

#### Testing Example

```ts
import {
  AllCommunityModule,
  CellValueChangedEvent,
  GridApi,
  GridOptions,
  ICellRendererComp,
  ICellRendererParams,
  ModuleRegistry,
  SelectionChangedEvent,

    month: "short",
    day: "numeric",
  });
};

    );

    const companyName: HTMLParagraphElement = document.createElement("p");

## Create a Basic Grid

Complete our [Quick Start](https://www.ag-grid.com/javascript-data-grid/getting-started/) (or open the example below in CodeSandbox / Plunker) to start with a basic grid, comprised of:

1. **Grid Options:** An object which holds all of the options for the grid, such as Row Data & Column Definitions.
2. **Row Data:** The data to be displayed.
3. **Column Definition:** Defines & controls grid columns.
4. **Container:** A div that contains and defines the grid's dimensions.
5. **Grid API:** Provides access to Grid API methods. Initialised when creating a new grid.

#### Basic Example

```ts
import {
  AllCommunityModule,
  GridApi,
  GridOptions,
  ModuleRegistry,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([AllCommunityModule]);

// Row Data Interface
interface IRow {
  make: string;
  model: string;
  price: number;
  electric: boolean;
}

// Grid API: Access to Grid API methods
let gridApi: GridApi;

// Grid Options: Contains all of the grid configurations
const gridOptions: GridOptions<IRow> = {
  // Data to be displayed
  rowData: [
    { make: "Tesla", model: "Model Y", price: 64950, electric: true },
    { make: "Ford", model: "F-Series", price: 33850, electric: false },
    { make: "Toyota", model: "Corolla", price: 29600, electric: false },
  ],
  // Columns to be displayed (Should match rowData properties)
  columnDefs: [
    { field: "make" },
    { field: "model" },
    { field: "price" },
    { field: "electric" },
  ],
};
// Create Grid: Create new grid within the #myGrid div, using the Grid Options object
gridApi = createGrid(
  document.querySelector<HTMLElement>("#myGrid")!,
  gridOptions,
);
```

[Live example: Basic Example](https://www.ag-grid.com/examples/deep-dive/basic-example/typescript)

## Load New Data

The Grid API provides a way of interacting with the grid. To update the data within the grid, we can use the `setGridOption` API. Let's test this by fetching some data and updating our grid with the response:

```jsx
fetch('https://www.ag-grid.com/example-assets/space-mission-data.json')
    .then(response => response.json())
    .then((data: any) => gridApi.setGridOption('rowData', data))
```

Now that we're loading data from an external source, we can empty our `rowData` array (which will allow the grid to display a loading spinner whilst the data is being fetched) and update our `colDefs` to match the new dataset:

```jsx
const gridOptions = {
    rowData: [],
    columnDefs: [
        { field: "mission" },
        { field: "company" },
        { field: "location" },
        { field: "date" },
        { field: "price" },
        { field: "successful" },
        { field: "rocket" }
    ]
}
```

When we run our application, we should see a grid with ~1,400 rows of new data, and new column headers to match:

#### Updating Example

```ts
import {
  AllCommunityModule,
  GridApi,
  GridOptions,
  ModuleRegistry,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([AllCommunityModule]);

// Grid API: Access to Grid API methods
let gridApi: GridApi;

// Row Data Interface
interface IRow {
  mission: string;
  company: string;
  location: string;
  date: string;
  time: string;
  rocket: string;
  price: number;
  successful: boolean;
}

// Grid Options: Contains all of the grid configurations
const gridOptions: GridOptions<IRow> = {
  // Data to be displayed
  rowData: [],
  // Columns to be displayed (Should match rowData properties)
  columnDefs: [
    { field: "mission" },
    { field: "company" },
    { field: "location" },
    { field: "date" },
    { field: "price" },
    { field: "successful" },
    { field: "rocket" },
  ],
};

// Create Grid: Create new grid within the #myGrid div, using the Grid Options object
gridApi = createGrid(
  document.querySelector<HTMLElement>("#myGrid")!,
  gridOptions,
);

// Fetch Remote Data
fetch("https://www.ag-grid.com/example-assets/space-mission-data.json")
  .then((response) => response.json())
  .then((data: any) => gridApi.setGridOption("rowData", data));
```

[Live example: Updating Example](https://www.ag-grid.com/examples/deep-dive/updating-example/typescript)

*Note: There are a large number of APIs available. See our [API Docs](https://www.ag-grid.com/javascript-data-grid/grid-api/) for an exhaustive list.*

## Configure Columns

Now that we have a basic grid with some arbitrary data, we can start to configure the grid with ***Column Properties***.

Column Properties can be added to one or more columns to enable/disable column-specific features. Let's try this by adding the `filter: true` property to the 'mission' column:

```jsx
columnDefs: [
    { field: "mission", filter: true },
    // ...
],
```

We should now be able to filter the 'mission' column - you can test this by filtering for the 'Apollo' missions:

#### Configuring Columns Example

```ts
import {
  AllCommunityModule,
  GridApi,
  GridOptions,
  ModuleRegistry,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([AllCommunityModule]);

// Row Data Interface
interface IRow {
  mission: string;
  company: string;
  location: string;
  date: string;
  time: string;
  rocket: string;
  price: number;
  successful: boolean;
}

// Grid API: Access to Grid API methods
let gridApi: GridApi;

// Grid Options: Contains all of the grid configurations
const gridOptions: GridOptions<IRow> = {
  // Data to be displayed
  rowData: [],
  // Columns to be displayed (Should match rowData properties)
  columnDefs: [
    { field: "mission", filter: true },
    { field: "company" },
    { field: "location" },
    { field: "date" },
    { field: "price" },
    { field: "successful" },
    { field: "rocket" },
  ],
};

// Create Grid: Create new grid within the #myGrid div, using the Grid Options object
gridApi = createGrid(
  document.querySelector<HTMLElement>("#myGrid")!,
  gridOptions,
);

// Fetch Remote Data
fetch("https://www.ag-grid.com/example-assets/space-mission-data.json")
  .then((response) => response.json())
  .then((data: any) => gridApi.setGridOption("rowData", data));
```

[Live example: Configuring Columns Example](https://www.ag-grid.com/examples/deep-dive/configure-columns-example/typescript)

*Note: Column properties can be used to configure a wide-range of features; refer to our [Column Properties](https://www.ag-grid.com/javascript-data-grid/column-properties/) page for a full list of features.*

### Default Column Definitions

The example above demonstrates how to configure a single column. To apply this configuration across all columns we can use ***Default Column Definitions*** instead. Let's make all of our columns filterable by adding the `defaultColDef` property to our Grid Options object, and setting `filter: true`:

```jsx
const gridOptions = {
    defaultColDef: {
        filter: true
    }
    // ...
}
```

The grid should now allow filtering on all columns:

#### Default Column Definitions Example

```ts
import {
  AllCommunityModule,
  GridApi,
  GridOptions,
  ModuleRegistry,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([AllCommunityModule]);

// Row Data Interface
interface IRow {
  mission: string;
  company: string;
  location: string;
  date: string;
  time: string;
  rocket: string;
  price: number;
  successful: boolean;
}

// Grid API: Access to Grid API methods
let gridApi: GridApi;

// Grid Options: Contains all of the grid configurations
const gridOptions: GridOptions<IRow> = {
  // Data to be displayed
  rowData: [],
  // Columns to be displayed (Should match rowData properties)
  columnDefs: [
    { field: "mission", filter: true },
    { field: "company" },
    { field: "location" },
    { field: "date" },
    { field: "price" },
    { field: "successful" },
    { field: "rocket" },
  ],
  // Configurations applied to all columns
  defaultColDef: {
    filter: true,
  },
};

// Create Grid: Create new grid within the #myGrid div, using the Grid Options object
gridApi = createGrid(
  document.querySelector<HTMLElement>("#myGrid")!,
  gridOptions,
);

// Fetch Remote Data
fetch("https://www.ag-grid.com/example-assets/space-mission-data.json")
  .then((response) => response.json())
  .then((data: any) => gridApi.setGridOption("rowData", data));
```

[Live example: Default Column Definitions Example](https://www.ag-grid.com/examples/deep-dive/default-columns-example/typescript)

*Note: Column Definitions take precedence over Default Column Definitions*

## Configure The Grid

So far we've covered creating a grid, updating the data within the grid, and configuring columns. This section introduces **Grid Options**, which control functionality that extends across both rows & columns, such as Pagination and Row Selection.

To use Grid Options, simply add the relevant property to the Grid Options object. Let's try this by adding `pagination: true` to our Grid Options:

```jsx
const gridOptions: GridOptions = {
    pagination: true
    // ...
}
```

We should now see Pagination has been enabled on the grid:

#### Grid Options Example

```ts
import {
  AllCommunityModule,
  GridApi,
  GridOptions,
  ModuleRegistry,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([AllCommunityModule]);

// Row Data Interface
interface IRow {
  mission: string;
  company: string;
  location: string;
  date: string;
  time: string;
  rocket: string;
  price: number;
  successful: boolean;
}

// Grid API: Access to Grid API methods
let gridApi: GridApi;

// Grid Options: Contains all of the grid configurations
const gridOptions: GridOptions<IRow> = {
  // Data to be displayed
  rowData: [],
  // Columns to be displayed (Should match rowData properties)
  columnDefs: [
    { field: "mission", filter: true },
    { field: "company" },
    { field: "location" },
    { field: "date" },
    { field: "price" },
    { field: "successful" },
    { field: "rocket" },
  ],
  // Configurations applied to all columns
  defaultColDef: {
    filter: true,
  },
  // Grid Options
  pagination: true,
};

// Create Grid: Create new grid within the #myGrid div, using the Grid Options object
gridApi = createGrid(
  document.querySelector<HTMLElement>("#myGrid")!,
  gridOptions,
);

// Fetch Remote Data
fetch("https://www.ag-grid.com/example-assets/space-mission-data.json")
  .then((response) => response.json())
  .then((data: any) => gridApi.setGridOption("rowData", data));
```

[Live example: Grid Options Example](https://www.ag-grid.com/examples/deep-dive/grid-options-example/typescript)

*Refer to our detailed [Grid Options](https://www.ag-grid.com/javascript-data-grid/grid-options/) documentation for a full list of options.*

## Format Cell Values

The data supplied to the grid usually requires some degree of formatting. For basic text formatting we can use **Value Formatters**.

**Value Formatters** are basic functions which take the value of the cell, apply some basic formatting, and return a new value to be displayed by the grid. Let's try this by adding the `valueFormatter` property to our 'price' column and returning the formatted value:

```jsx
columnDefs: [
    {
        field: "price",
        // Return formatted value
        valueFormatter: (params) => { return '£' + params.value.toLocaleString(); }
    },
],
```

The grid should now show the formatted value in the 'price' column:

#### Value Formatter Example

```ts
import {
  AllCommunityModule,
  GridApi,
  GridOptions,
  ModuleRegistry,
  ValueFormatterParams,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([AllCommunityModule]);

// Row Data Interface
interface IRow {
  mission: string;
  company: string;
  location: string;
  date: string;
  time: string;
  rocket: string;
  price: number;
  successful: boolean;
}

// Grid API: Access to Grid API methods
let gridApi: GridApi;

// Grid Options: Contains all of the grid configurations
const gridOptions: GridOptions<IRow> = {
  // Data to be displayed
  rowData: [],
  // Columns to be displayed (Should match rowData properties)
  columnDefs: [
    {
      field: "mission",
      filter: true,
    },
    { field: "company" },
    { field: "location" },
    { field: "date" },
    {
      field: "price",
      valueFormatter: (params: ValueFormatterParams) => {
        return "£" + params.value.toLocaleString();
      },
    },
    { field: "successful" },
    { field: "rocket" },
  ],
  // Configurations applied to all columns
  defaultColDef: {
    filter: true,
  },
  // Grid Options
  pagination: true,
};

// Create Grid: Create new grid within the #myGrid div, using the Grid Options object
gridApi = createGrid(
  document.querySelector<HTMLElement>("#myGrid")!,
  gridOptions,
);

// Fetch Remote Data
fetch("https://www.ag-grid.com/example-assets/space-mission-data.json")
  .then((response) => response.json())
  .then((data: any) => gridApi.setGridOption("rowData", data));
```

[Live example: Value Formatter Example](https://www.ag-grid.com/examples/deep-dive/value-formatter-example/typescript)

*Note: Read our [Value Formatter](https://www.ag-grid.com/javascript-data-grid/value-formatters/) page for more information on formatting cell values*

## Custom Cell Components

**Value Formatters** are useful for basic formatting, but for more advanced use-cases we can use **Cell Renderers** instead.

**Cell Renderers** allow you add custom HTML & JS within cells. To use a Cell Renderer, set the `cellRenderer` prop on a column, with the value as the name of your Cell Renderer.

Let's try this by creating a new component to display the company logo in the 'company' column:

```jsx
class CompanyLogoRenderer {
    eGui;

    // Optional: Params for rendering. The same params that are passed to the cellRenderer function.
    init(params) {
        let companyLogo = document.createElement('img');
        companyLogo.src = `https://www.ag-grid.com/example-assets/space-company-logos/${params.value.toLowerCase()}.png`
        companyLogo.setAttribute('style', 'display: block; width: 25px; height: auto; max-height: 50%; margin-right: 12px; filter: brightness(1.1)');
        let companyName = document.createElement('p');
        companyName.textContent = params.value;
        companyName.setAttribute('style', 'text-overflow: ellipsis; overflow: hidden; white-space: nowrap;');
        this.eGui = document.createElement('span');
        this.eGui.setAttribute('style', 'display: flex; height: 100%; width: 100%; align-items: center')
        this.eGui.appendChild(companyLogo)
        this.eGui.appendChild(companyName)
    }

    // Required: Return the DOM element of the component, this is what the grid puts into the cell
    getGui() {
        return this.eGui;
    }

    // Required: Get the cell to refresh.
    refresh(params) {
        return false
    }
}
```

And then adding `cellRenderer: CompanyLogoRenderer` to the 'company' column definition:

```jsx
columnDefs: [
    {
        field: "company",
        cellRenderer: CompanyLogoRenderer
    },
    // ...
],
```

Now, when we run the grid, we should see a company logo next to the name:

#### Cell Renderer Example

```ts
import {
  AllCommunityModule,
  GridApi,
  GridOptions,
  ICellRendererComp,
  ICellRendererParams,
  ModuleRegistry,
  ValueFormatterParams,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([AllCommunityModule]);

// Grid API: Access to Grid API methods
let gridApi: GridApi;

class CompanyLogoRenderer implements ICellRendererComp {
  eGui!: HTMLSpanElement;

  // Optional: Params for rendering. The same params that are passed to the cellRenderer function.
  init(params: ICellRendererParams) {
    const companyLogo: HTMLImageElement = document.createElement("img");
    companyLogo.src = `https://www.ag-grid.com/example-assets/space-company-logos/${params.value.toLowerCase()}.png`;
    companyLogo.setAttribute(
      "style",
      "display: block; width: 25px; height: auto; max-height: 50%; margin-right: 12px; filter: brightness(1.1)",
    );

    const companyName: HTMLParagraphElement = document.createElement("p");
    companyName.textContent = params.value;
    companyName.setAttribute(
      "style",
      "text-overflow: ellipsis; overflow: hidden; white-space: nowrap;",
    );

    this.eGui = document.createElement("span");
    this.eGui.setAttribute(
      "style",
      "display: flex; height: 100%; width: 100%; align-items: center",
    );
    this.eGui.appendChild(companyLogo);
    this.eGui.appendChild(companyName);
  }

  // Required: Return the DOM element of the component, this is what the grid puts into the cell
  getGui() {
    return this.eGui;
  }

  // Required: Get the cell to refresh.
  refresh(params: ICellRendererParams): boolean {
    return false;
  }
}

// Row Data Interface
interface IRow {
  mission: string;
  company: string;
  location: string;
  date: string;
  time: string;
  rocket: string;
  price: number;
  successful: boolean;
}

const gridOptions: GridOptions<IRow> = {
  // Data to be displayed
  rowData: [],
  // Columns to be displayed (Should match rowData properties)

## Handle Grid Events

In the last section of this tutorial we're going to hook into events raised by the grid using ***Grid Events***.

To be notified of when an event is raised by the grid we need to add the relevant `on[EventName]` property to our Grid Options, and provide a function to handle the event.

Let's try this out by enabling cell editing in our DefaultColDefs with `editable: true` and hooking into the `onCellValueChanged` event to log the new value to the console:

```jsx
const gridOptions = {
    // Configurations applied to all columns
    defaultColDef: {
        editable: true,
        // ...
    },
    // Log new value when cell value changes
    onCellValueChanged: (event) => {
        console.log(`New Cell Value: ${event.value}`)
    }
    // ...
}
```

Now, when we click on a cell we should be able to edit it and see the new value logged to the console:

#### Complete Example

```ts
import {
  AllCommunityModule,
  CellValueChangedEvent,
  GridApi,
  GridOptions,
  ICellRendererComp,
  ICellRendererParams,
  ModuleRegistry,
  ValueFormatterParams,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([AllCommunityModule]);

// Grid API: Access to Grid API methods
let gridApi: GridApi;

class CompanyLogoRenderer implements ICellRendererComp {
  eGui!: HTMLSpanElement;

  // Optional: Params for rendering. The same params that are passed to the cellRenderer function.
  init(params: ICellRendererParams) {
    const companyLogo: HTMLImageElement = document.createElement("img");
    companyLogo.src = `https://www.ag-grid.com/example-assets/space-company-logos/${params.value.toLowerCase()}.png`;
    companyLogo.setAttribute(
      "style",
      "display: block; width: 25px; height: auto; max-height: 50%; margin-right: 12px; filter: brightness(1.1)",
    );

    const companyName: HTMLParagraphElement = document.createElement("p");
    companyName.textContent = params.value;
    companyName.setAttribute(
      "style",
      "text-overflow: ellipsis; overflow: hidden; white-space: nowrap;",
    );

    this.eGui = document.createElement("span");
    this.eGui.setAttribute(
      "style",
      "display: flex; height: 100%; width: 100%; align-items: center",
    );
    this.eGui.appendChild(companyLogo);
    this.eGui.appendChild(companyName);
  }

  // Required: Return the DOM element of the component, this is what the grid puts into the cell
  getGui() {
    return this.eGui;
  }

  // Required: Get the cell to refresh.
  refresh(params: ICellRendererParams): boolean {
    return false;
  }
}

// Row Data Interface
interface IRow {
  mission: string;
  company: string;
  location: string;
  date: string;
  time: string;
  rocket: string;
  price: number;
  successful: boolean;
}

const gridOptions: GridOptions<IRow> = {
  // Data to be displayed
  rowData: [],
  // Columns to be displayed (Should match rowData properties)
  columnDefs: [
    {
      field: "mission",
      filter: true,
    },
    {
      field: "company",
      cellRenderer: CompanyLogoRenderer,
    },
    {
      field: "location",
    },
    { field: "date" },
    {
      field: "price",
      valueFormatter: (params: ValueFormatterParams) => {
        return "£" + params.value.toLocaleString();
      },
    },
    { field: "successful" },
    { field: "rocket" },
  ],
  // Configurations applied to all columns
  defaultColDef: {
    editable: true,
    filter: true,
  },
  // Grid Options & Callbacks
  pagination: true,
  onCellValueChanged: (event: CellValueChangedEvent) => {
    console.log(`New Cell Value: ${event.value}`);
  },
};

// Create Grid: Create new grid within the #myGrid div, using the Grid Options object
gridApi = createGrid(
  document.querySelector<HTMLElement>("#myGrid")!,
  gridOptions,
);

// Fetch Remote Data
fetch("https://www.ag-grid.com/example-assets/space-mission-data.json")
  .then((response) => response.json())
  .then((data: any) => gridApi.setGridOption("rowData", data));
```

*Refer to our [Grid Events](https://www.ag-grid.com/javascript-data-grid/grid-events/) documentation for a full list of events raised by the grid*

## Test Your Knowledge

Let's put what you've learned so far into action by modifying the grid:

1. Enable filtering on all columns

   *Hint: `filter` is a Column Definition property*
2. Enable multiple row selection

   *Hint: `rowSelection` is a Grid Option property*
3. Log a message to the console when a row selection is changed

   *Hint: `onSelectionChanged` is a Grid Event*
4. Format the Date column using `.toLocaleDateString()`;

   *Hint: Use a `valueFormatter` on the 'Date' column to format its value*
5. Add a Cell Renderer to display [ticks](https://www.ag-grid.com/example-assets/icons/tick-in-circle.png) and [crosses](https://www.ag-grid.com/example-assets/icons/cross-in-circle.png) in place of checkboxes on the 'Successful' column:

   *Hint: Use a `cellRenderer` on the 'successful' column*

Once complete, your grid should look like the example below. If you're stuck, check out the source code to see how its done:

## Summary

Congratulations! You've completed the tutorial and built your first grid. By now, you should be familiar with the key concepts of AG Grid:

- **Row Data:** Your data, in JSON format, that you want the grid to display.
- **Column Definitions:** Define your columns and control column-specific functionality, like sorting and filtering.
- **Default Column Definitions:** Similar to Column Definitions, but applies configurations to all columns.
- **Grid Options:** Configure functionality which extends across the entire grid.
- **Grid Events:** Events raised by the grid, typically as a result of user interaction.
- **Value Formatters:** Functions used for basic text formatting
- **Cell Renderers:** Add your own components to cells
