timer-miniprogram

小程序定时器管理库，更合理地使用 setTimeout 和 setInterval，在页面显示时重启定时器，页面隐藏时暂停定时器，页面卸载时清除定时器。 写这个库的缘由详看。

使用

可参考 example 目录下的示例项目或参照以下流程：

1. 通过 npm 安装

npm install --save timer-miniprogram

安装完成之后在微信开发者工具中点击构建 npm。

2. 导入小程序适配版本的 timer-miniprogram

import { TimerBehavior } from 'timer-miniprogram'
// 在页面中使用
Page({
  behaviors: [TimerBehavior],
  onReady() {
    const timer1 = this.$setTimeout(() => {
      console.log('setTimeout')
    })
    this.$clearTimeout(timer1)

    const timer2 = this.$setInterval(() => {
      console.log('setInterval')
    })
    this.$clearInterval(timer2)
  }
})

// 在组件中使用
Components({
  behaviors: [TimerBehavior],
  ready() {
    const timer1 = this.$setTimeout(() => {
      console.log('setTimeout')
    })
    this.$clearTimeout(timer1)

    const timer2 = this.$setInterval(() => {
      console.log('setInterval')
    })
    this.$clearInterval(timer2)
  }
})

eslint 配置

为了让团队更好地遵守定时器使⽤规范，你还可以配置 eslint 增加代码提示，配置如下：

// .eslintrc.js
module.exports = {
    'rules': {
        'no-restricted-globals': ['error', {
            'name': 'setTimeout',
            'message': 'Please use TimerBehavior and this.$setTimeout instead. see the link: https://github.com/o2team/timer-miniprogram'
        }, {
            'name': 'setInterval',
            'message': 'Please use TimerBehavior and this.$setInterval instead. see the link: https://github.com/o2team/timer-miniprogram'
        }, {
            'name': 'clearInterval',
            'message': 'Please use TimerBehavior and this.$clearInterval instead. see the link: https://github.com/o2team/timer-miniprogram'
        }, {
            'name': 'clearTimout',
            'message': 'Please use TimerBehavior and this.$clearTimout  instead. see the link: https://github.com/o2team/timer-miniprogram'
        }]
    }
}
