What is tuya-connector?

Tuya Open Platform—API User Guide

Tuya provides a set of HTTP APIs and signature verification logic. You need to implement the logic during when you integrate the APIs.

tuya-connector provides capabilities to sign a request, refresh, store, and renew a token, and encapsulate common APIs. You can quickly connect to Tuya open platform.

Installation

npm install @tuya/tuya-connector-nodejs

# or
yarn add @tuya/tuya-connector-nodejs

Get started

import { TuyaContext  } from '@tuya/tuya-connector-nodejs';

const tuya = new TuyaContext({
  baseUrl: 'https://openapi.tuyacn.com',
  accessKey: 'xx',
  secretKey: 'xx',
});

const device = await tuya.device.detail({
  device_id: 'device_id'
});

Advanced development

Custom tokenStore

By default, tokenStore is implemented based on memory. We recommend that you implement the store instance in your service. In the following code block, the Redis Store is used as an example.

// tokenStore.ts
import { TuyaTokenStorInterface, TuyaTokensSave } from '@tuya/tuya-connector-nodejs';
import IORedis from 'ioredis';

export class RedisTokenStore implements TuyaTokenStorInterface {
  private readonly client: IORedis.Redis;
  private readonly key: string;
  constructor(client: IORedis.Redis, key: string = 'tuya::token') {
    this.client = client;
    this.key = key;
  }

    async setTokens(tokens: TuyaTokensSave): Promise<boolean> {
    const res = await this.client.set(this.key, JSON.stringify(tokens));
    return ! ! res;
  }
  async getAccessToken(): Promise<string | undefined> {
    const jsonStr = await this.client.get(this.key) || '{}';
    const tokens: TuyaTokensSave = JSON.parse(jsonStr);
    return tokens && tokens.access_token;
  }
  async getRefreshToken(): Promise<string | undefined> {
    const jsonStr = await this.client.get(this.key) || '{}';
    const tokens: TuyaTokensSave = JSON.parse(jsonStr);
    return tokens.refresh_token;
  }
}

// index.ts
import { RedisTokenStore } from './tokenStore';
import IoRedis from 'ioredis';
const redis = new IoRedis();

const tuya = new TuyaContext({
  baseUrl: 'https://openapi.tuyacn.com',
  accessKey: 'xx',
  secretKey: 'xx',
  store: new RedisTokenStore(redis),
});

Custom request of httpClient

tuya-connector uses Axios as httpClient by default, and exposes replaceable parameters. If necessary, you can also customize httpClient.

import axios from 'axios';
import { TuyaContext  } from '@tuya/tuya-connector-nodejs';

const tuya = new TuyaContext({
  baseUrl: 'https://openapi.tuyacn.com',
  accessKey: 'xx',
  secretKey: 'xx',
  rpc: axios
});

Request of other OpenAPIs

tuya-connector encapsulates common APIs, and declares the types of reqeust and response parameters. You can customize additional API requests.

import { TuyaContext  } from '@tuya/tuya-connector-nodejs';

const tuya = new TuyaContext({
  baseUrl: 'https://openapi.tuyacn.com',
  accessKey: 'xx',
  secretKey: 'xx',
});

const { data } = await tuya.request({
  method: 'GET',
  path: '/v1.0/xx',
  body: {},
});

Other issues

1. Apply for authorization key. On the Cloud Development Platform, you can create a project to get the access ID and access secret of the cloud application.

2. Global error codes. For more information, see Global Error Codes.
