# Mattermost Client
|
|
|
|
[](https://www.npmjs.com/package/@mattermost/client)
|
|
|
|
This package contains the JavaScript/TypeScript client for [Mattermost](https://github.com/mattermost/mattermost). It's used by [the Mattermost web app](https://github.com/mattermost/mattermost/tree/master/webapp/channels) and related projects.
|
|
|
|
## Installation
|
|
|
|
### JavaScript
|
|
|
|
```sh
|
|
$ npm install @mattermost/client
|
|
```
|
|
|
|
### TypeScript
|
|
|
|
```sh
|
|
$ npm install @mattermost/client @mattermost/types
|
|
```
|
|
|
|
## Usage
|
|
|
|
To use the client, create an instance of `Client4`, set the server URL, and log in, and then you can start making requests.
|
|
|
|
```js
|
|
import {Client4} from '@mattermost/client';
|
|
|
|
const client = new Client4();
|
|
client4.setUrl('https://mymattermostserver.example.com');
|
|
|
|
client4.login('username', 'password').then((user) => {
|
|
// ...
|
|
});
|
|
```
|
|
|
|
If you already have a session token or a user access token, you can call `Client4.setToken` instead of logging in.
|
|
|
|
```js
|
|
import {Client4} from '@mattermost/client';
|
|
|
|
const client = new Client4();
|
|
client4.setUrl('https://mymattermostserver.example.com');
|
|
|
|
client4.setToken('accesstoken');
|
|
```
|
|
|
|
If needed, methods exist to set other headers such as the User-Agent (`Client4.setUserAgent`), the CSRF token (`Client4.setCSRF`), or any extra headers you wish to include (`Client4.setHeader`).
|
|
|
|
Methods of `Client4` which make requests to the server return a `Promise` which does the following:
|
|
|
|
- On success, the promise resolves to a `ClientResponse<T>` object which contains the the [Response](https://developer.mozilla.org/en-US/docs/Web/API/Response) (`response`), a [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) of headers (`headers`), and the data sent from the server (`data`).
|
|
- On an error, the promise rejects with a `ClientError` which contains the error message and the URL being requested. If the error happened on the server, the status code and an error ID (`server_error_id`) are included.
|
|
|
|
```js
|
|
let user;
|
|
try {
|
|
user = (await client.getUser('userid')).data;
|
|
} catch (e) {
|
|
console.error(`An error occurred when making a request to ${e.url}: ${e.message}`);
|
|
}
|
|
```
|
|
|
|
