This is the 8th day of my participation in the August More text Challenge. For details, see: August More Text Challenge

Scenario: The front end is separated from the back end, and the front end is deployed to the back end, requiring the code to be pushed to the git directory on the back end after each front end packaging. So I wrote the following scenario.

Install toolkit

npm i cpx shelljs --save-dev
Copy the code

See the Cloud shellJS Chinese document

CPX NPM document

Add js file to the project root directory

// Introduce the required toolkits
const cpx = require("cpx");
const shell = require('shelljs')
// Add the fs module to read files
const fs = require('fs');
/* fs.existssync (path), check if the second file exists, and return true shell.which('git') to check if git is available */
if (fs.existsSync('./package.json') && shell.which('git')) {
  /** fs.readfilesync () is the way to read files synchronously, and it will block
  var package = fs.readFileSync('./package.json');
  if (typeof package == "object") {
    var result = JSON.parse(package);
    if (result.gitcopy) {
      if(! fs.existsSync(result.gitcopy.dir)) {/** exec() exec(command [, options] [, callback]) command 
      
       : complete command to be executed on the command line options 
       : optional parameter, JSON Object async: Asynchronous execution. If you provide a callback method, this value must be true, Any other arguments to the child_process.exec() method of node.js can be called with callback:

The error "error > stdout < String > | < Buffer > stderr < String > | < Buffer > return values: In synchronous mode, returns a ShellString (shelljs v0.6.xf returns a ShellString of the form {code:... , stdout:... , stderr:... } object); In asynchronous mode, an object */ of child_process is returned
        
      
        shell.exec('git clone ' + result.gitcopy.git + ' ' + result.gitcopy.dir);
      }
      shell.exec('cd ' + result.gitcopy.dir + ' && git checkout ' + result.gitcopy.checkout + ' && git pull '.function (err, stdout, stderr) {
        if(! err) {/** cpx.copy(source, dest, options, callback) source {string} -- copy glob of the target file. Dest {string} -- The file path of the destination directory.

          cpx.copy("dist/**", result.gitcopy.dir + result.gitcopy.webapp, {}, function () {
            shell.exec('cd ' + result.gitcopy.dir + '&& git pull && git add * && git commit -m "automatic update" && git push'.function (err, stdout, stderr) {
              if (err) {
                console.log("No Update!");
              } else {
                console.log("Successful！"); }}); })}else {
          console.log(err); }}); }}else {
    console.log("Configuration file is not a valid object"); }}else {
  console.log('Please check that Git has been installed successfully and that the configuration file exists! ');
}
Copy the code

Modify the package.json file

Add the following code for tier 1 nodes:

{
  "gitcopy": {
    "git": "https://git.jd.com/bt/jd-bt-middle-template.git"."dir": ".. /bt-middle-template-main"."webapp": "/bt-middle-template-main/src/main/webapp"."checkout": "master_jmm_default_images"}}Copy the code
