- Using the CLI `strapi generate:controller user`. Read the [CLI documentation](../cli/CLI.md#strapi-generatecontroller) for more information.
- Manually create a JavaScript file named `User.js` in `./api/**/controllers` which contains at least one [endpoint](#adding-endpoints).
## Adding Endpoints
Each controller’s action must be an `async` function and receives the `context` (`ctx`) object as first parameter containing the [request context](../guides/requests.md) and the [response context](../guides/responses.md). The action has to be bounded by a route.
#### Example
In this example, we are defining a specific route in `./api/hello/config/routes.json` that takes `Hello.index` as handler. It means that every time a web browser is pointed to the `/hello` URL, the server will called the `index` action in the `Hello.js` controller. Our `index` action will return `Hello World!`. You can also return a JSON object.
**Path —** `./api/hello/config/routes.json`.
```json
{
"routes": [
{
"method": "GET",
"path": "/hello",
"handler": "Hello.index"
}
]
}
```
**Path —** `./api/hello/controllers/Hello.js`.
```js
module.exports = {
// GET /hello
index: async (ctx) => {
ctx.send('Hello World!');
}
};
```
> Note: A route handler can only access the controllers defined in the `./api/**/controllers` folders.
