How to add a header comment to a file using gulp.
I was uglifying some javascript using node and gulp and wanted to add a comment header to the top of the file. Gulp-header to the rescue!
This feeds the information from package.json:
var gulp = require("gulp");
var header = require("gulp-header");
// Import package.json as a local data source
var pkg = require("./package.json");
var comment = [
"/**",
" * <%= pkg.name %> - <%= pkg.description %>",
" * @author <%= pkg.author %>",
" * @version v<%= pkg.version %>",
" * @link <%= pkg.homepage %>",
" * @license <%= pkg.license %>",
" */",
""
].join("\n");
gulp.task("add-header", function() {
gulp
.src(["sourcefile.js"])
.pipe(header(comment, { pkg: pkg }))
.pipe(gulp.dest("."));
});
The output in the JavaScript file will look something like:
/**
* Name - Description
* @author Destin Moulton
* @version v0.3.0
* @link https://github.com/destinmoulton/projectname
* @license MIT
