gulp-wrap

A gulp plugin to wrap a file contents.

Usage

Firstly, install gulp-wrap-file as a development dependency:

npm install gulp-wrap-file --save-dev

Then, add it into your gulpfile.js:

Wrap the commonjs contents with amd:

var wrapper = require("gulp-wrap-file");

gulp.src("./src/**/*.js")
    .pipe(wrap({type: 'amd'}))
    .pipe(gulp.dest("build"));

Wrap the contents by your file wrapper:

var wrap = require("gulp-wrap-file");

gulp.src("./src/**/*.js")
    .pipe(wrap({wrapper: 'define({file});'}))
    .pipe(gulp.dest("build"));

Wrap the contents with modName:

var wrap = require("gulp-wrap-file");

gulp.src("./src/**/*.js")
    .pipe(wrap({wrapper: 'define("src/{modName}",function((require, exports, module){ {file} }));'}))
    .pipe(gulp.dest("build"));

example

input

//input.js
function foo() { console.log("hello world"); }

gulpfile.js

var wrap = require("gulp-wrap-file");

gulp.src("input.js")
    .pipe(wrap({wrapper: 'define("demo/{modName}",function((require, exports, module){ {file} }));'}))
    .pipe(gulp.dest("build"));

same to the wrapper for function

var wrap = require("gulp-wrap-file");

gulp.src("input.js")
    .pipe(wrap({wrapper: function(content, file){
        return 'define("demo/'+file.modName+'",function((require, exports, module){ '+content+' }));'
    }}))
    .pipe(gulp.dest("build"));

output

define("demo/input",function((require, exports, module){ function foo() { console.log("hello world"); } }));
