javascript - Accessing the process / environment from a grunt template

Question

I have some code in a grunt.js file which is working with 0.3 but breaks on 0.4:

{
    dest: '<%= process.env.DEST %>/index.html'
}

In 0.3 process is defined and so I can access variables defined in the environment inside the template when I am e.g. passing file paths to other plugins.

Is there an alternative approach to this which will work in 0.4? Or a way to put a breakpoint in while the template is rendering so that I can see what variables are available?

Answer 1

The default data is the config object. You can add the environment variable to the config object or just use it directly.

grunt.initConfig({
    destination: process.env.DEST,
    task: {
        target: {
            dest: '<%= destination %>/index.html'
        }
    },
});

or

grunt.initConfig({
    task: {
        target: {
            dest: process.env.DEST + '/index.html'
        }
    },
});
