print-date-webpack-plugin/plugin.ts

Plugin can print date before and after bundle info, also can print some lines before compilation started.

let lines:number = 0,
    print_begin:boolean = false,
    print_end:boolean = true,
    init: boolean = false;


function printDate(options: {
    lines: number | undefined,
    print_begin: boolean | undefined,
    print_end: boolean | undefined
} | undefined) {
    if(typeof options !== 'undefined'){
        if(typeof options.lines === 'number') {
            lines = options.lines;
        };

        if(typeof options.print_begin !== 'undefined') {
            print_begin = !!options.print_begin;
        };

        if(typeof options.print_end !== 'undefined') {
            print_end = !!options.print_end;
        };
    };
};

function print(msg: string) {
	var date = msg + (new Date()).toLocaleString();
	console.log('\x1b[36m', date ,'\x1b[0m');
}

printDate.prototype.apply = function(compiler: any) {
    print_begin && compiler.plugin("compilation", function(compilation: any) {
        if(init) for(var i = 0; i < lines; i++) {
          console.log("");
        };

        init = true;
      
        compilation.plugin('record', function() {
          print("Begin: ");
        });
    });

    print_end && compiler.plugin('done', function() {
        setTimeout(function() {
            print("End: ");
        }, 0);
    });
};
