Using Gulp to Improve Your Angular Workflow

Maintaining the build process for an Angular app can be quite involved. A typical build pipeline will involve validating the source code for styling, passing unit tests and end-to-end tests, minifying, annotating, bundling, creating source maps, transpiling and more. In this seminar I will show you how to use Gulp to manage your entire Angular workflow.

1. Using Gulp to Improve Your Angular Workflows Jennifer Bland
2. 2 Topics We Will Cover Bundling Validation Minification Source Maps ES6 Babel
3. 3 Why Use Gulp? Manages our workflow process Chain together all pieces of our existing code Tool of choice for most large projects Can install globally
6. Let’s Get Started
7. 7 Installing Gulp & First Task 1. npm install gulp —save-dev 2. create Gulpfile.js file 3. create our first gulp task 4. run gulp to test
8. BUNDLING Combing all JavaScript files into one file
9. 9 Concatenating Files 1. npm install gulp-concat —save-dev 2. require ‘gulp-concat’ 3. add concat task in Gulpfile 4. run gulp to test
10. MINIFICATION Reducing size of our bundled files
11. 11 Minifying Files 1. npm install gulp-uglify —save-dev 2. require ‘gulp-uglify’ 3. pipe output of concat to uglify 4. run gulp to test
12. LOADING DEPENDENCIES Not require all gulp files
13. 13 Loading Plugins 1. npm install gulp-load-plugins —save-dev 2. require ‘gulp-load-plugins’ 3. replace concat with $.concat and uglify with $.uglify 4. delete dist folder 5. run gulp to test
14. RESOLVING MINIFICATION ISSUES Don’t want to rewrite our code so do this instead
15. 15 Angular & Minification var app = angular.moduel(‘gulp-demo’); func^on myCtrl(myWidget) { …. } app.controller(‘myCtrl’, myCtrl); app.controller(‘myCtrl’, [‘myWidget’, myCtrl]); myCtrl.$inject(‘myWidget’);
16. 16 Angular & Minification 1. npm install gulp-ng-annotate —save-dev 2. pipe source files to $.ngAnnotate() 3. run gulp to test
17. SOURCEMAPS Being able to debug concatenated and minified code
18. 18 Sourcemaps 1. npm install gulp-sourcemaps —save-dev 2. $.sourcemaps.init() 3. $.sourcemaps.write() 4. run gulp to test
19. ES6 AND BABEL Use ES6 regardless of browser being used
20. 20 ES6 and Babel 1. npm install gulp-babel babel-preset-2015 —save-dev 2. pipe source files to $.ngAnnotate() 3. run gulp to test
21. WATCHING FOR CODE CHANGES Build automatically when changes occur
22. 22 Watching for Code Changes 1. change default task to scripts 2. create new default task that runs scripts and watches for changes 3. save source files into a variable 4. run gulp to test
23. CODE VALIDATION Verify code meets our coding standards
24. 24 Code Validation 1. create .eslintrc file 2. put your coding standards into this file 3. nam install eslint-config-angular eslint-plugin-angular gulp-eslint —save-dev 4. add lint task 5. add lint task to default 6. run gulp to test
