Week 5: NPM and Gulp

Set up Gulp

we'll do this together

1. Pull down this project
2. Install gulp globally: npm install -g gulp #PATH
3. Install gulp locally: npm install gulp
4. Create a gulpfile.js in the root of this project
5. Require Gulp: var gulp = require('gulp');
6. Create a new task, call it "copy": gulp.task('copy', function(){ ... });
7. Use gulp.src and pipe to gulp.dest to copy files from js/*.js to dist/

• gulp.src('js/app/*.js')
• .pipe(gulp.dest('dist/'));

Install and Set up a jshint

we'll do this together

1. Install jshinter
2. require the gulp-jshint module
3. Create a new "jshint" task
4. Use gulp.src to get the src files
5. pipe that to jshint()
6. pipe that to jshint.reporter()
7. Install jshint-stylish
8. Change the reporter to jshint.reporter('jshint-stylish')
9. Add the new task to the default task
10. Run gulp
11. Fix the errors

Install and set up concatenation

do this on your own

1. Install concatenator
2. require the gulp-concat module
3. Create a new "buildApp" task
4. Use gulp.src to get the src files
5. pipe that to concat(app.js)
6. pipe that to gulp.dest ./dist
7. Check out the app.js file
8. Now that you have this new file, reference that instead of the app files in index.html

Install and Set up Uglification

do this on your own

1. Install minifier
2. require the gulp-uglify module
3. Add the uglify() function to the buildApp pipes
4. Check out the app.js file

Repeat for Vendor Files

on your own

1. Create a "buildVendor" task
2. concat and uglify the files found in there

Combine App and Vendor Builds

on your own

1. Create a new "build" task `gulp.task('build', ['buildApp', 'buildVendor']);
2. Add the build task to the default task

Install and set up karma

do this one on your own

1. Install via npm: karma, karma-jasmine, karma-phantomjs-launcher locally
2. Add the following task

gulp.task('karma', function (done) {
  new Server({
    configFile: __dirname + '/karma.conf.js',
    singleRun: true
  }, done).start();
});

3. Remove the singleRun line if you want it to run with autowatch
4. See this for more information

Combine jshint and karma

on your own

1. Create a new task "test" that will call both the jshint task and the karma task

Install and set up a watch task

we'll do this together

1. Create a new task called "watch"
2. Use gulp.watch() to watch for changes to the js/app files and run "test" and "build" when changed
3. Use it again to watch for changes to js/tests and run "test" when changed
