使用场景

• 在 egg.js 中使用 Bull.js

开启插件

// {app_root}/config/plugin.js
exports.bulls = {
  enable: true,
  package: "egg-bulls"
};

插件配置

单实例

// {app_root}/config/config.default.js
exports.bulls = {
  client: {
    topic: "queue",
    queueOptions: {
      redis: {
        host: "localhost",
        port: 6379,
        db: 0,
        password: "Pass1234"
      }
    }
  }
};

多实例

// {app_root}/config/config.default.js
exports.bulls = {
  clients: {
    queue1: {
      // topic must same with key
      topic: "queue1",
      queueOptions: {
        redis: {
          host: "localhost",
          port: 6379,
          db: 1,
          password: "Pass1234"
        }
      }
    },
    queue2: {
      // topic must same with key
      topic: "queue2",
      queueOptions: {
        redis: {
          host: "localhost",
          port: 6379,
          db: 2,
          password: "Pass1234"
        }
      }
    }
  }
};

或者使用相同的 Redis 配置

// Use the same redis configuration
exports.bulls = {
  clients: {
    queue1: { topic: "queue1" },
    queue2: { topic: "queue2" }
  },
  default: {
    queueOptions: {
      redis: {
        host: "localhost",
        port: 6379,
        db: 0,
        password: "Pass1234"
      }
    }
  }
};

更多配置请查看 config/config.default.js

示例

文件挂载路径为{app_root}/app/{topic}，在 app 上访问 apptopic

单实例

// 配置

// topic 默认为 queue 时,如果使用自定义名称挂载路径变为{app_root}/app/{topic}

// {app_root}/config/config.default.js
exports.bulls = {
  client: {
    topic: "queue",
    redis: {
      host: "localhost",
      port: 6379,
      db: 0,
      password: "Pass1234"
    }
  }
};
// 可以直接在 app 上使用
app.bulls.process(job => {
  console.log(job.data.job1); // 'this is a job'
});
app.bulls.add({ job1: "this is a job" });
app.bulls.on('completed', (job)=>{
//  do something
})
app.bulls.on('failed', (err,job)=>{
// do something
});

// 或者批量添加

// {app_root}/app.js
class AppBootHook{
  constructor(app){
    this.app = app
  }
  async didReady(){
    const jobs = [{
      // topic：queue
      queue:'queue'
      data:{
        // job data
      },
      jobName:'job-Name',
      options:{
        // job options
      }
    }];
    await this.app.addJobtToQueue(jobs)
  }
}
// {app_root}/app/queue/status.js
module.exports = app => {
  return {
    completed(job) {
      // do something
    }
    failed(job,error){
      // do something
    }
    //
    // use async
    //
    async completed(job) {
      // do something
    }
    async failed(job,error){
      // do something
    }
  };
};
// {app_root}/app/queue/handle.js
module.exports = app => {
  return job => {
    // do something
  }
};



// topic 为自定义时

// {app_root}/config/config.default.js
exports.bulls = {
  client: {
    topic: "test",
    redis: {
      host: "localhost",
      port: 6379,
      db: 0,
      password: "Pass1234"
    }
  }
};

// 可以直接在 app 上使用
app.bulls.process(job => {
  console.log(job.data.job1); // 'this is a job'
});
app.bulls.add({ job1: "this is a job" });
app.bulls.on('completed', (job)=>{
//  do something
})
app.bulls.on('failed', (err,job)=>{
// do something
});

// 或者

// {app_root}/app.js
class AppBootHook{
  constructor(app){
    this.app = app
  }
  async didReady(){
    const jobs = [{
      // topic：test
      queue:'test'
      data:{
        // job data
      },
      jobName:'job-Name',
      options:{
        // job options
      }
    }];
    await this.app.addJobtToQueue(jobs)
  }
}

// {app_root}/app/test/status.js
module.exports = app => {
  return {
    completed(job) {
      // do something
    }
    failed(job,error){
      // do something
    }
    //
    // use async
    //
    async completed(job) {
      // do something
    }
    async failed(job,error){
      // do something
    }
  };
};
// {app_root}/app/test/handle.js
module.exports = app => {
  return job => {
    // do something
  }
};

多实例

// 配置

// {app_root}/config/config.default.js
exports.bulls = {
  clients: {
    queue1: {
      topic: "queue1",
      redis: {
