How do you use context?

Hi,

Sorry, but how do you use context for storing tokens, and then how do you retrieve them?

I was trying something along the lines of below, but I'm wrong :)

const api = got.extend({
  hooks: {
    beforeRequest: [
      (options) => {
        if (!options.context || !options.context.token) {
          options.context.token = getToken();
        }
      },
    ],
  },
  (options) => {
    headers: {
      Authorization: `Bearer ${options.context.token}`,
    },
  }
});

You're setting token but trying to access access_token.

Yes, I did. Fixed that, thanks. I was mainly concerned with (options) not being available in headers?

Is this how to do it?

headers: (options) => {
      `Authorization: Bearer ${options.context.token}`,
    },

Nope: RequestError: Cannot add property token, object is not extensible

Is it possible to access options in headers?

const api = got.extend({
	hooks: {
		beforeRequest: [
			options => {
				if (!options.context.token) {
					options.context.token = getToken();
				}
				options.headers.authorization = `Bearer ${options.context.token}`;
			}
		]
	}
});

// use it
await api('https://example.com/endpoint', {
	context: {token: 'my-token'}
});

context is never frozen, so you can always modify it. you can also update the token in mutable defaults:

const api = got.extend({
	mutableDefaults: true,
	context: {token: 'initial-token'}
});

// later, update the token
api.defaults.options.context.token = 'new-token';
