Gulp-wrap NPM | npm.io

gulp-wrap

A gulp plugin to wrap the stream contents with a lodash template.

Usage

First, install gulp-wrap as a development dependency:

npm install --save-dev gulp-wrap

Then, add it to your gulpfile.js:

Wrap the contents with an inline template:

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

gulp.src("./src/*.json")
    .pipe(wrap('angular.module(\'text\', []).value(<%= contents %>);', {}, { parse: false /* do not parse the JSON file for template data */ }))
    .pipe(gulp.dest("./dist"));

Wrap the contents with a template from file:

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

gulp.src("./src/*.json")
    .pipe(wrap({ src: 'path/to/template.txt'}))
    .pipe(gulp.dest("./dist"));

Use parsed contents within a template (supports JSON and YAML):

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

gulp.src("./src/*.json")
    .pipe(wrap('Hello, <%= contents.title %>, have a <%= contents.adjective %> day.'))
    .pipe(gulp.dest("./dist"));

Provide additional data and options for template processing:

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

gulp.src("./src/*.json")
    .pipe(wrap('BEFORE <%= data.contents %> <%= data.someVar %> AFTER', { someVar: 'someVal'}, { variable: 'data' }))
    .pipe(gulp.dest("./dist"));

This gulp plugin wraps the stream contents in a template. If you want the stream contents to be the templates use the gulp-template plugin.

Template

The stream contents will be available in the template using the contents key. If the file extension is json, yaml, or yml then the contents will be parsed before being passed to the template. Properties from the vinyl file will be available in the template under the file object and are local to that stream. User supplied data values will always take precedence over namespace clashes with the file properties.
