> Octokit plugin for GitHub’s recommended request throttling
|
||||
|
||||
[](https://www.npmjs.com/package/@octokit/plugin-throttling)
|
||||
[](https://github.com/octokit/plugin-throttling.js/actions?workflow=Test)
|
||||
|
||||
Implements all [recommended best practices](https://docs.github.com/en/rest/guides/best-practices-for-integrators) to prevent hitting secondary rate limits.
|
||||
|
||||
## Usage

<table>

|
||||
|
||||
Load `@octokit/plugin-throttling` and [`@octokit/core`](https://github.com/octokit/core.js) (or core-compatible module) directly from [esm.sh](https://esm.sh)
|
||||
|
||||
```html
|
||||
<script type="module">
|
||||
import { Octokit } from "https://esm.sh/@octokit/core";
|
||||
import { throttling } from "https://esm.sh/@octokit/plugin-throttling";
|
||||
</script>
|
||||
```
|
||||
|
||||
</td></tr>
|
||||
<tr><th>
|
||||
Node
|
||||
</th><td>
|
||||
|
||||
Install with `npm install @octokit/core @octokit/plugin-throttling`. Optionally replace `@octokit/core` with a core-compatible module.
|
||||
|
||||
```js
|
||||
import { Octokit } from "@octokit/core";
|
||||
import { throttling } from "@octokit/plugin-throttling";
|
||||
```

|
||||
|
||||
The code below creates a "Hello, world!" issue on every repository in a given organization. Without the throttling plugin it would send many requests in parallel and would hit rate limits very quickly. But the `@octokit/plugin-throttling` slows down your requests according to the official guidelines, so you don't get blocked before your quota is exhausted.
|
||||
|
||||
The `throttle.onSecondaryRateLimit` and `throttle.onRateLimit` options are required. Return `true` to automatically retry the request after `retryAfter` seconds.
|
||||
|
||||
```js
|
||||
const MyOctokit = Octokit.plugin(throttling);
|
||||
|
||||
const octokit = new MyOctokit({
|
||||
auth: `secret123`,
|
||||
throttle: {
|
||||
onRateLimit: (retryAfter, options, octokit, retryCount) => {
|
||||
octokit.log.warn(
|
||||
`Request quota exhausted for request ${options.method} ${options.url}`,
|
||||
);
|
||||
|
||||
if (retryCount < 1) {
|
||||
// only retries once
|
||||
octokit.log.info(`Retrying after ${retryAfter} seconds!`);
|
||||
return true;
|
||||
}
|
||||
},
|
||||
onSecondaryRateLimit: (retryAfter, options, octokit) => {
|
||||
// does not retry, only logs a warning
|
||||
octokit.log.warn(
|
||||
`SecondaryRateLimit detected for request ${options.method} ${options.url}`,
|
||||
);
|
||||
},
|
||||
},
|
||||
});
|
||||
|
||||
async function createIssueOnAllRepos(org) {
|
||||
const repos = await octokit.paginate(
|
||||
octokit.repos.listForOrg.endpoint({ org }),
|
||||
);
|
||||
return Promise.all(
|
||||
repos.map(({ name }) =>
|
||||
octokit.issues.create({
|
||||
owner,
|
||||
repo: name,
|
||||
title: "Hello, world!",
|
||||
}),
|
||||
),
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
Pass `{ throttle: { enabled: false } }` to disable this plugin.
|
||||
|
||||
### Clustering
|
||||
|
||||
Enabling Clustering support ensures that your application will not go over rate limits **across Octokit instances and across Nodejs processes**.
|
||||
|
||||
First install either `redis` or `ioredis`:
|
||||
|
||||
```
|
||||
# NodeRedis (https://github.com/NodeRedis/node_redis)
|
||||
npm install --save redis
|
||||
|
||||
# or ioredis (https://github.com/luin/ioredis)
|
||||
npm install --save ioredis
|
||||
```
|
||||
|
||||
Then in your application:
|
||||
|
||||
```js
|
||||
import Bottleneck from "bottleneck";
|
||||
import Redis from "redis";
|
||||
|
||||
const client = Redis.createClient({
|
||||
/* options */
|
||||
});
|
||||
const connection = new Bottleneck.RedisConnection({ client });
|
||||
connection.on("error", err => console.error(err));
|
||||
|
||||
const octokit = new MyOctokit({
|
||||
auth: 'secret123'
|
||||
throttle: {
|
||||
onSecondaryRateLimit: (retryAfter, options, octokit) => {
|
||||
/* ... */
|
||||
},
|
||||
onRateLimit: (retryAfter, options, octokit) => {
|
||||
/* ... */
|
||||
},
|
||||
|
||||
// The Bottleneck connection object
|
||||
connection,
|
||||
|
||||
// A "throttling ID". All octokit instances with the same ID
|
||||
// using the same Redis server will share the throttling.
|
||||
id: "my-super-app",
|
||||
|
||||
// Otherwise the plugin uses a lighter version of Bottleneck without Redis support
|
||||
Bottleneck
|
||||
}
|
||||
});
|
||||
|
||||
// To close the connection and allow your application to exit cleanly:
|
||||
await connection.disconnect();
|
||||
```
|
||||
|
||||
To use the `ioredis` library instead:
|
||||
|
||||
```js
|
||||
import Redis from "ioredis";
|
||||
const client = new Redis({
|
||||
/* options */
|
||||
});
|
||||
const connection = new Bottleneck.IORedisConnection({ client });
|
||||
connection.on("error", (err) => console.error(err));
|
||||
```
|
||||
|
||||
