Official Auth0 Actions TypeScript definitions, which will help you code and test your project’s Actions on external editors and IDEs.
## 🚀 Getting Started
**Prerequisites:**
- [Node.js v18 or higher](https://nodejs.org/en/download)
- [TypeScript 5.5 or higher](https://www.typescriptlang.org/download) (for development)
- An [Auth0 account](https://auth0.com/signup)
- Basic knowledge of [Auth0 Actions](https://auth0.com/docs/customize/actions)
- A code editor with TypeScript support (e.g., [VS Code](https://code.visualstudio.com/))
**Installation:**
Install the package using npm:
```bash
npm install --save-dev @auth0/actions
```
Or using yarn:
```bash
yarn add --dev @auth0/actions
```
Or using pnpm:
```bash
pnpm add --save-dev @auth0/actions
```
**Usage:**
Import the TypeScript definitions into your Auth0 Actions using one of the following approaches:
**JSDoc @import:**
Use this approach when you want to enable IntelliSense without changing your existing JavaScript code structure:
```javascript
/** @import {Event, PostLoginAPI} from "@auth0/actions/post-login/v3" */
/**
* Handler that will be called during the execution of a PostLogin flow.
*
* @param {Event} event - Details about the user and the context in which they are logging in.
* @param {PostLoginAPI} api - Interface whose methods can be used to change the behavior of the login.
*/
exports.onExecutePostLogin = async (event, api) => {
const user = event.user;
// Your Action logic here
if (user.email?.endsWith('@example.com')) {
api.user.setAppMetadata('department', 'internal');
}
}
```
**JSDoc @param:**
Use this approach for type safety in JavaScript files using import statements in JSDoc comments:
```javascript
/**
* Handler that will be called during the execution of a PostLogin flow.
*
* @param {import('@auth0/actions/post-login/v3').Event} event - Details about the user and the context in which they are logging in.
* @param {import('@auth0/actions/post-login/v3').PostLoginAPI} api - Interface whose methods can be used to change the behavior of the login.
*/
exports.onExecutePostLogin = async (event, api) => {
const user = event.user;
// Your Action logic here
if (user.email?.endsWith('@example.com')) {
api.user.setAppMetadata('department', 'internal');
}
}
```
**TypeScript import:**
Use this approach when developing with TypeScript for full type checking and modern syntax:
```typescript
import type { Event, PostLoginAPI } from '@auth0/actions/post-login/v3';
/**
* Handler that will be called during the execution of a PostLogin flow.
*
* @param {Event} event - Details about the user and the context in which they are logging in.
* @param {PostLoginAPI} api - Interface whose methods can be used to change the behavior of the login.
*/
exports.onExecutePostLogin = async (event: Event, api: PostLoginAPI) => {
const user = event.user;
// Your Action logic here
if (user.email?.endsWith('@example.com')) {
api.user.setAppMetadata('department', 'internal');
}
};
```
> **⚠️ Important:** When using TypeScript, you must compile your code to JavaScript before deploying to Auth0. The Auth0 Actions runtime only executes JavaScript. Use the TypeScript compiler (`tsc`) to transpile your `.ts` files to `.js` files, before it can be deployed. You must also include JSDoc comments to enable Intellisense in the Dashboard.
