WeChat applet development: workflow built on Gulp

Currently, when developing WeChat mini programs, there are roughly four available technical solutions, namely: native development of WeChat mini programs, using the wepy framework, using the mpvue framework, and using the taro framework

will be continuously updated. thank you for your support.

WeChat applet development workflow based on Gulp

Applicable scenarios

Three development options, each with its own advantages and disadvantages. Using third-party framework development, you can enjoy the development convenience brought by the framework, but for the many new features and functions of the mini program, such as WXS module, custom components and Plug-ins , etc. are restricted by third-party frameworks and cannot be used.

The development model of native small programs is too simple. In terms of style, students who are used to writing less, stylus and sass will not be able to tolerate the writing method of wxss. Based on this, I decided to use gulp is an automated tool to build a set of basic templates for WeChat applet development. On the basis of fully retaining the functions and characteristics of WeChat applet, you can also use less to write styles and add image compression. , command line to quickly create templates and other features, so developed, happy, happy!

Features

• WeChat applet project built based on gulp less

• Automatic compression of project images

• ESLint code inspection

• Use the command line to quickly createpage, template and component

Getting Started

0. Before starting, please make sure that node and npm have been installed and installed globally. gulp-cli

$ npm install --global gulp-cli

1. Download the code

$ git clone https://github.com/YangQiGitHub/wx-miniprogram-boilerplate.git

2. Enter the directory and install the dependencies

$ cd wx-miniprogram-boilerplate && npm install

3. Compile the code, generate the dist directory, and use the developer tools to open the dist Directory

$ npm run dev

4. Create a new page, template or component

  gulp auto -p mypage           创建名为mypage的page文件
  gulp auto -t mytpl            创建名为mytpl的template文件
  gulp auto -c mycomponent      创建名为mycomponent的component文件
  gulp auto -s index -p mypage  复制pages/index中的文件创建名称为mypage的页面

5. Compile before uploading the code

$ npm run build

6. Upload the code, review and release

Gulp Description

Tasks:
  dev              开发编译，同时监听文件变化
  build            整体编译

  clean            清空产出目录
  wxml             编译wxml文件（仅仅copy）
  js               编译js文件，同时进行ESLint语法检查
  json             编译json文件（仅仅copy）
  wxss             编译less文件为wxss
  img              编译压缩图片文件
  watch            监听开发文件变化
  
  auto             自动根据模板创建page,template或者component(小程序自定义组件)

gulp auto 

选项：
  -s, --src        copy的模板                     [字符串] [默认值: "_template"]
  -p, --page       生成的page名称                                       [字符串]
  -t, --template   生成的template名称                                   [字符串]
  -c, --component  生成的component名称                                  [字符串]
  --msg            显示帮助信息                                           [布尔]

示例：
  gulp auto -p mypage           创建名为mypage的page文件
  gulp auto -t mytpl            创建名为mytpl的template文件
  gulp auto -c mycomponent      创建名为mycomponent的component文件
  gulp auto -s index -p mypage  复制pages/index中的文件创建名称为mypage的页面

Q&A

Q: Why are js conversion, style completion and code compression not added to the workflow?
A: WeChat developer tools come with functions such as babel converting ES6 to ES5, style completion, and js code compression. No additional additions are required in this workflow.

Q: What are the uses of the files in the _template directory?
A: Use the gulp auto command to automatically generate files. The -s parameter can specify the copy object. By default, it is the folder in the corresponding directory. The files in _template are copy objects. Developers can customize files under _template based on business needs.

Q: Will the files in the _template directory be compiled into the dist directory?
A: No.

TODO

• [x] Code comments

• ##[x] Standard command line usage

• [x] eslint

• [ ] Introduce commonly used CSS libraries, such as weui and the like
