Task definition and execution

This feature allows you to define and execute tasks. In the code sample, a default task is defined which depends on another task named 'dependency'. When the default task is run, it first ensures that the 'dependency' task is executed.

"use strict";
let jake = require('jake');

task('default', ['dependency'], function () {
  console.log('Running default task');
});

task('dependency', function () {
  console.log('Running dependency task');
});

File operations

Jake can perform various file operations such as creating directories, copying files, and iterating over sets of files. In this example, a task named 'createFile' is defined to process all JavaScript files in the current directory, create a new directory named 'build', and copy all files from 'src/' to 'build/'.

"use strict";
let jake = require('jake');

task('createFile', function () {
  jake.FileList('*.js').forEach(function (file) {
    console.log('Processing file: ' + file);
  });
  jake.mkdirP('build');
  jake.cpR('src/', 'build/');
});

Running shell commands

Jake allows you to run shell commands directly from your tasks. This example shows a task named 'deploy' that runs a shell command to push changes to the master branch of a git repository. The output of the command is printed to the console.

"use strict";
let jake = require('jake');

task('deploy', function () {
  let command = 'git push origin master';
  jake.exec(command, {printStdout: true}, function () {
    console.log('Deployed to master');
  });
});
