Grunt.initconfig method

For a module configuration, it accepts an object as a parameter. The members of this object correspond to module one by one, which uses the same name.

The specific settings for each target need to refer to the documentation for that template. In terms of cssmin, the parameters of the minify target are as follows:

    • Expand: If set to True, the placeholder (that is, *) of the following file name is extended to a specific file name.
    • CWD: The directory where the file (input) needs to be processed.
    • src: Represents a file that needs to be processed. If an array is used, each item of the array is a file name, and wildcard characters can be used.
    • dest: Indicates the file name or directory in which it was processed.
    • ext: Indicates the file suffix name after processing.

Grunt Common Function Description:

Grunt.loadnpmtasks: Loads the modules required to complete the task.
