Usage

Use Mixin API

const { MixinApi } = require('@mixin.dev/mixin-node-sdk');

const keystore = {
  app_id: '',
  session_id: '',
  server_public_key: '',
  session_private_key: '',
};
const client = MixinApi({ keystore });

// Use Promise
client.user.profile().then(console.log);
// Use async await
async function getMe() {
  const me = await client.user.profile();
  console.log(me);
}

Receive Mixin Messenger messages

const { BlazeKeystoreClient } = require('@mixin.dev/mixin-node-sdk/blaze');

const keystore = {
  app_id: '',
  session_id: '',
  server_public_key: '',
  session_private_key: '',
};
const config = {
  parse: true,
  syncAck: true,
};

const client = BlazeKeystoreClient(keystore, config);
client.loop({
  onMessage(msg) {
    console.log(msg);
  },
});

OAuth

const { MixinApi, getED25519KeyPair, base64RawURLEncode } = require('@mixin.dev/mixin-node-sdk');

const code = ''; // from OAuth url
const app_id = ''; // app_id of your bot
const client_secret = ''; // OAuth Client Secret of your bot

const { seed, publicKey } = getED25519KeyPair(); // Generate random seed and ed25519 key pairs

let client = MixinApi();
const { scope, authorization_id } = await client.oauth.getToken({
  client_id: app_id,
  code,
  ed25519: base64RawURLEncode(publicKey),
  client_secret,
});
const keystore = {
  app_id,
  scope,
  authorization_id,
  session_private_key: Buffer.from(seed).toString('hex'),
};
client = MixinApi({ keystore });
const user = await client.user.profile();

Use the sdk in web browser

This SDK uses node Buffer, which is not available in web browser. You can use polyfills to make it work.

For example, you can use vite-plugin-node-polyfills for vite.

// vite.config.js
import { nodePolyfills } from 'vite-plugin-node-polyfills';
// ...
export default defineConfig({
  // ...
  plugins: [
    nodePolyfills({
      globals: {
        Buffer: true,
      },
    }),
  ],
});
