# TypeScript

An official TypeScript binding for the EdgeWorkers JavaScript API is available to help you design your EdgeWorkers functions.

TypeScript supports these features to help write, maintain, and refactor your JavaScript code:

- Autocomplete functions within the supported integrated development environments (IDE) for the EdgeWorkers JavaScript object model.

- Lint code analysis.

- A TypeScript compiler to find problems before activating your EdgeWorker version.

For more information about TypeScript go to [the language's homepage](https://www.typescriptlang.org/).

You can review the steps to [install typescript dependencies](/edge-workers/dev-environment-tutorial#install-typescript-dependencies) in the development environment tutorial.

1. Enter this command to install the `DefinitelyTyped` definition for the EdgeWorkers API inside an existing TypeScript project:

```shell
$ npm install @types/akamai-edgeworkers
```

2. The `node_packages/@types/akamai-edgeworkers` directory contains the type bindings. Set your `tsconfig.json` file to use `es2022` as the compilation target and module code generator:

```json
{
    "compilerOptions": {
    "module": "es2022",
    "target": "es2022",
        //...
    }
}
```
