Suggest deploy path in a Grunt task - gruntjs

Question

I have a Grunt task to automatize the deploy of my webapp on webserver.
On My webserver I have 3 paths:
/www/myApp (production)
/www/myApp_rc
I have a package.json file
{
...
"ftpDeployPath":"myApp_rc" //or /www/myApp
...
}
and this is my task
{'ftp-deploy': {
toMyServer: {
auth: {
host: '10.7.88.87',
port: 21,
authKey: 'key1'
},
src: 'deploy',
dest: '<%= pkg.ftpDeployPath %>',
forceVerbose: true
}
}
}
When I want deploy, every time I have to check and eventually edit package.json file.
Is there any way to show a prompt (bu grunt console) to allow me to select the right deploy path?

Answer 1

You can probably try using grunt-prompt task with 'input' question type and your "ftpDeployPath" as 'config'. Or, modify your gruntfile to use command line options (http://gruntjs.com/frequently-asked-questions#dynamic-alias-tasks) and run your tasks as external tools from WebStorm (Settings | Tools | External tools) - you can add $Prompt$ macro to tool parameters to get a prompt for option value when running a tool

Using a combination of command line arguments and a custom task, you can modify configuration for tasks before you run them. Let's start first by modifying the template string for dist; change it to access a grunt.option() param called deployPath our custom task will set:
grunt.initConfig({
'ftp-deploy': {
toMyServer: {
auth: {
host: '10.7.88.87',
port: 21,
authKey: 'key1'
},
src: 'deploy',
dest: '<%= grunt.option('deployPath') %>',
forceVerbose: true
}
}
});
Next, craft a custom task that sets the grunt.option('deployPath') parameter. The task below will set deployPath to myApp when you run grunt deploy:prod. If you run just grunt deploy, the path is set to myApp_rc. Once the path is chosen, the custom then calls the ftp-deploy task:
function deployTask(grunt) {
var deployPath = (this.args[0] === 'prod') ? 'myApp' : 'myApp_rc';
grunt.option('deployPath', deployPath);
grunt.task.run('ftp-deploy');
}
grunt.registerTask('deploy', deployTask);
