A really simple to use module to use discord's OAuth2 API.
Please check out discord's OAuth2 documentation: https://discord.com/developers/docs/topics/oauth2
npm install discord-oauth2One parameter is passed to the class constructor:
Since the module uses a modified version of Eris's request handler, it takes the same options, all of them default to the default Eris REST options if no options are passed.
Request handler options:
agent: A HTTPS Agent used to proxy requests
requestTimeout: A number of milliseconds before requests are considered timed out.
latencyThreshold: The average request latency at which the RequestHandler will start emitting latency errors.
ratelimiterOffset: A number of milliseconds to offset the ratelimit timing calculations by.
Others, you can pass these options to the class constructor so you don't have to pass them each time you call a function:
clientId: Your application's client id.
clientSecret: Your application's client secret.
redirectUri: Your URL redirect uri.
credentials: Base64 encoding of the UTF-8 encoded credentials string of your application, you can pass this in the constructor to not pass it every time you want to use the revokeToken() method.
In the Eris Library, client extends the events modules and the client is passed to the RequestHandler so it's able to emit events, this modified RequestHandler extends events so it can emit the same events.
There are only two events, debug and warn.
Takes an object with the following properties:
clientId: Your application's client id. Can be omitted if provided on the client constructor.
clientSecret: Your application's client secret. Can be omitted if provided on the client constructor.
scope: The scopes requested in your authorization url, can be either a space-delimited string of scopes, or an array of strings containing scopes.
redirectUri: Your URL redirect uri. Can be omitted if provided on the client constructor.
grantType: The grant type to set for the request, either authorization_code or refresh_token.
code: The code from the querystring (grantType authorization_code only).
refreshToken: The user's refresh token (grantType refresh_token only).
Returns a promise which resolves in an object with the access token.
Please refer to discord's OAuth2 documentation for the parameters needed.

To easily debug any issues you are having, you can access the following properties of the error object thrown:
req: The HTTP request sent to discord.
res: The HTTP response sent from discord to our request.
code: If the error is a DiscordHTTPError, it will be the HTTP status code of the response (same as res.statusCode).
If the error is a DiscordRESTError, it will be a Discord API JSON error code.
response: An object containing properties that describe the error.
If the error is a DiscordHTTPError, the object will have the error and error_description properties.
If the error is a DiscordRESTError, the object will have the message and code (JSON error code. See code.) properties.
message: If the error is a DiscordHTTPError, it will be a string including the status of the HTTP request and the endpoint used.
If the error is a DiscordRESTError, it will be a string including the error code and it's meaning.
stack: The error stack trace.
// error.response for DiscordRESTError
{
message: 'Missing Permissions',
code: 50013
}// error.response for DiscordHTTPError
{
error: 'invalid_request',
error_description: 'Invalid "code" in request.'
