discord-request

Looking for an API Wrapper? Check out discord-api-methods instead. This package is low level, and works best in libraries as opposed to applications.

A Discord HTTP client that handles formatting and parsing requests.

Usage

This package works best in conjuction with discord-api-types. To begin, install both:

npm install discord-request discord-api-types

Then you can combine the two (with or without typing the results):

import { Client } from "discord-request";
import {
	Routes,
	RESTGetAPIApplicationGuildCommandsResult,
} from "discord-api-types/v10";

const client = new Client();
client.setToken(process.env.DISCORD_TOKEN);

const guildCommands = client.get(
	Routes.applicationGuildCommands(applicationId, guildId)
) as Promise<RESTGetAPIApplicationGuildCommandsResult>;

Options

When creating a new client, you can configure it by passing in optional arguments:

const instance = new Client({
	timeout: 1000,
	userAgent: "My Discord Bot",
}).setToken(process.env.DISCORD_TOKEN);

Every parameter listed below is optional.

• api: The API URL to use. Defaults to https://discord.com/api.
• version: The API version to use. Defaults to 10.
• cdn: The CDN URL to use. Defaults to https://cdn.discordapp.com.
• headers: An object of additional headers to send with each request.
• userAgent: The user agent to use. Defaults to Discord Request v0.
• timeout: The number of milliseconds to wait before timing out a request. Defaults to 15000 (15 seconds).
• abortSignal: An AbortSignal to use when you need to cancel all unfinished requests to shut down the application.
• onRequest: See callbacks below.

Callbacks

onRequest?: (path: string, init: RequestInit) => void;

Runs when a request is sent to the Discord API. Passes information used to send the request.

Client Configuration

There are various getters and setters you can use to configure the client once instantiated.

const instance = new Client();
instance.userAgent = "My Discord Bot";
console.log(instance.userAgent);

Setting Token

To set an application token for the client to use, call setToken after you instantiate it.

const instance = new Client();
instance.setToken(process.env.DISCORD_TOKEN);

Sending Requests

To send a request, use the get, post, patch, put, or delete methods.

import { Client } from "discord-request";

const instance = new Client().setToken(process.env.DISCORD_TOKEN);
const route = "...";
let result;

// GET
result = await instance.get(route);

// POST
result = await instance.post(route, {
	body: {
		key: "value",
	},
});

// PUT
result = await instance.put(route, {
	body: {
		key: "value",
	},
});

// PATCH
result = await instance.patch(route, {
	body: {
		key: "value",
	},
});

// DELETE
result = await instance.delete(route);

Request Options

You can pass these options to each HTTP request method. Every parameter listed below is optional.

• authorization (boolean): Whether to use the authorization header.
• authorizationPrefix (string): The authorization prefix to use. Defaults to "Bot".
• formData (FormData): The body to send as form data.
• body (BodyInit | object): The body to send with the request. If you have defined formData or files this will be sent as payload_json in the form data.
• files (Attachment[] | undefined): A list of up to 10 files to upload and send as part of the request.
  • Attachment objects should consist of an optional id snowflake (for editing existing attachments), a name string, and a data Blob.
• headers (HeadersInit): Headers to add to the request.
• rawBody (boolean, defaults to false): If true, the body will not be processed before sending to Discord.
• query (URLSearchParams): Query parameters to add to the request.
• reason (string): If provided, an audit log entry will be made with this value.
• versioned (boolean): A boolean on whether to use the versioned API. By default, requests will set a specific API version.

Request Errors

This library will throw several different errors based on the response.

• RequestError - If the request fails for any reason, this error will be thrown with the error message.
• RateLimitError - If your application is currently being Rate Limited by Discord, this error will be thrown with the parsed information.
• DiscordRequestError - If Discord's API returns an error with an error key, this error will be thrown with the parsed information.
