![]() ![]() How to mutate original array in Javascript. Where do you put CSS files in a rails app directory? In 2020 it is just enough to use -prod flag, when building project: ng build -prod minify(filePath, icon to turn this feature off, but it seems to like to disappear once the code has been pretty printed so you may need to reload the page and click it quickly. join(_dirname, 'dist')) Ĭonst filePath = path. Minify.js // npm i -save-dev minifier fs-jetpack const jetpack = require( 'fs-jetpack') Ĭonst files = jetpack. Ng build -env=prod -no-sourcemap & node minify You can use # - env= # -no-sourcemap # minify =>. the -env=prod tells it to use your prod environment constants file.the -prod tells it to minify hash, and gzip.This is my angular-cli-build.js var Angular2App = require( 'angular-cli/lib/broccoli/angular2-app') Īnswer 1: ng build - prod -env = prod Is there any specific setting to use for angular-cli-build, or some additional plugin to install and use? Still waiting for angular2-templatecache and transformers.As the title says, when I run "ng serve" angular-cli generates normal css whereas I expect to get the minified version. For HTML in Angularjs, there was template-cache, which could pick all the templates from a single html file.Īngular Dart had components, but it also had transformers which namespaced the CSS selectors according to components and also transformed the url of css files in each component. In angular 2, doing this can cause css selector conflicts. ![]() This was possible in Angularjs as there were no components, and whole CSS of the app could be placed in a single file. ![]() # Starts webpack-dev-server at port 8080 serving the appĬurrently, all the CSS and HTML files of the application are served separately, there is no way to bundle them in a single file. To run webpack-dev-server which serves the app for development purposes and supports live-reload, run ❯ gulp dev-server # This will create javascript bundles with source maps and copy html, css file in the 'dist' directory To create development package of the application, run ❯ gulp dev # This directory can then be served by a web server # This will create minified javascript bundles and copy all the html, css file in the 'dist' directory. To create production package of the application, run ❯ gulp deploy Gulp tasks are defined in gulpfile.js for these things, and for running webpack. Gulp Tasksįor the application to work, along with the transpiled javascript, the html and css files for each of the components should be placed at the path given as the templateUrl or styleUrl in the typescript file for the component. index.html just imports these two files.įor debugging, source maps are enabled in the bundles created for the development mode using gulp. All other code is bundles into a files named bundle.js. It bundles all the third-party dependencies import in vendor.ts into a file. It has source maps enabled which helps in debugging. Typescript compiler configuration is present in tsconfig.json. package.json contains all the required packages which include angular 2 and its dependecies, webpack, gulp, typescript etc. vendor.ts imports all the third-party library the the app uses, which includes angular 2 in this case. Other components are inside the components directory with a separate directory for each component which contains its html and css files along with the typescript file. app/seed-app.ts has the main app component. This setup is built upon the angular2-seed app. ![]() The full code for this setup is present at. I explored various solutions and found the following set up using webpack to bundle javascript, gulp for running tasks, npm for package management to be the best. There are different choices available for each of the step and there is no fixed way to do anything.Īll this can get very confusing when trying to start a new angular project. Along with this, the HTML and CSS of each individual component in the application should be present at the right place. For debugging, source maps need to be enabled and for production, javascript needs to be minified. When developing in typescript, it has to be transpiled to javascript in a way such that its modules can be loaded by the browser. Production and Development set-up for Angular 2 with TypeScript using Webpack and Gulpīuilding modular, better structured web applications is now easier with Angular 2, but this comes with a new set of challenges on developing, packaging and deploying these applications. ![]()
