In order to start working on a different app, you’ll have to manually edit the port in your NGINX config. Unfortunately, our /sockjs-node/ NGINX proxy above will only route traffic to one of these apps - meaning you can only use the live reload with one app at a time. # proxy my-project traffic location ^~ /my-project/ Īll of these apps will attempt to use /sockjs-node/ to communicate with their respective ng serve live reload server. This step is optional if you only plan on working on a single Angular 2+ app.
#Angular cli livereload not working update#
Serve your Angular 2+ app from a unique portįirst, update your Angular project’s angular.json file to ng serve on a unique port - one that isn’t already in use by another Angular app. What I want is to bind Gulps scss live reload with Angular 2s html live reload. Another Angular shield mashup icon because there's not enough on the internet already. If you have a problem or need assistance after hours: please call. However, it also blocks some of the traffic the ng serve feature uses to trigger the live reload feature, so your app will lose the ability to refresh itself when its source files are changed.įortunately, it’s possible to proxy this live reload traffic and regain live reload functionality. For example, say you use a local webserver like NGINX to hide your app behind a URL like This common setup allows the app to communicate with a server hosted at a different domain or port without causing cross-origin issues. Unfortunately, it’s pretty easy to break some features of this command. This command builds the app, serves it (using webpack-dev-server), and then watches for changes to source files, incrementally rebuilding and reloading the app when changes are detected. Perhaps the best feature of the CLI is the ng serve command. The CLI cleanly replaces the hodge-podge of custom gulp, grunt, or npm scripts that power the build behind every AngularJS (Angular 1) app. One of my favorite features of Angular 2+ is the Angular CLI. Tight feedback loops are one of my favorite aspects of front-end development. The Angular CLI uses Webpack under the hood.Not my snappiest title, but this topic is too near to my heart to obscure with puns. Whether it uses Webpack, SystemJS, etc under the hood is then only a concern of developers looking for more advanced use cases. The common soluton that framework authors have adopted as of late is to create a CLI (command line interface) tool that exposes commands frequently required operations on your codebase.
While these can sometimes help you get up and running faster, they often lack official support from the official team and you're a lot more likely to run into trouble with whatever tooling preferences that repo maintainer decided on. There are a myriad of boilerplate repos on Github for every possible framework, build tool, and library.
This is a common question not only for Angular but also all other modern JS frameworks. How do we bundle and run our applications? Should we use Gulp? Webpack? SystemJS? How are these all different? While going through online examples to learn a framework is great, it skips one of the more confusing parts of modern web development: Building & Running Apps with the Angular CLI.Using Angular's HTTP Client to Interact with Servers.Using BehaviorSubject for Values That Change over Time.Subjects, Observers, Observables, and Operators.A Better Way to Learn RxJS & Observables.Linking & Navigating Between Components.Routing & Navigation with Angular's Router.Modularizing Angular Apps with NgModule.Formatting Data in Angular Templates with Pipes.Building UI Functionality with Angular Components.Understanding The Differences Between AngularJS and Angular.
