Executing a task within a Grunt operation

Question

Executing a task within a Grunt operation

I have integrated Grunt (a task-based command line build tool for JavaScript projects) into my project. One of the tasks I've created is a custom tag, and I am curious if it is feasible to execute a command within this tag.

Specifically, I am working with Closure Templates and need "the task" to invoke the jar file that pre-compiles the Soy file into a JavaScript file.

Currently, I am executing this jar file from the command line, but my goal is to automate this process by incorporating it as a task in Grunt.

Answer №1

If you're looking to streamline your processes, consider incorporating grunt plugins for assistance:

grunt-shell is a great option:

shell: {
  create_directory: {
    command: 'mkdir new_folder'
  }
}

Alternatively, you can try using grunt-exec with commands like:

exec: {
  clear_logs: {
    command: 'rm -f *.log'
  },
  view_files: {
    command: 'ls -l **',
    stdout: true
  },
  display_grunt_version: {
    command: function(grunt) { return 'echo ' + grunt.version; },
    stdout: true
  }
}

Take a look at grunt.util.spawn:

grunt.util.spawn({
  cmd: 'rm',
  args: ['-rf', '/tmp'],
}, function completed() {
  grunt.log.ok('/tmp has been deleted');
});

After finding a solution, I wanted to share it with you.

I work with grunt in node.js, and to execute terminal commands, you will need to use the 'child_process' module.

Here's an example:

var myTerminal = require("child_process").exec,
    commandToBeExecuted = "sh myCommand.sh";

myTerminal(commandToBeExecuted, function(error, stdout, stderr) {
    if (!error) {
         //do something
    }
});

In my experience with the latest grunt version (0.4.0rc7), I encountered issues with both grunt-exec and grunt-shell as they did not seem to be updated to handle the newest grunt features. On the other hand, using child_process's exec proved to be asynchronous, which added complexity to my workflow.

To overcome this challenge, I decided to implement Jake Trent's solution and included shelljs as a development dependency in my project. This allowed me to easily and synchronously run tests:

var shell = require('shelljs');

...

grunt.registerTask('jquery', "download jquery bundle", function() {
  shell.exec('wget http://jqueryui.com/download/jquery-ui-1.7.3.custom.zip');
});

People are suggesting child_process, however consider utilizing execSync to view the output.

grunt.registerTask('test', '', function () {
        var exec = require('child_process').execSync;
        var result = exec("phpunit -c phpunit.xml", { encoding: 'utf8' });
        grunt.log.writeln(result);
});
