# Configure Project EnvironmentsĬreate a new file ‘~src/environments/’ and update with the following: export const environment = from './environments/environment' Ĭonst bootstrap = () => platformBrowserDynamic().bootstrapModule(AppModule) Ĭonsole.error('HMR is not enabled for webpack-dev-server!') Ĭonsole.log('Are you using the -hmr flag for ng serve?') īootstrap().catch(err => console.log(err)) Here we are going to create one more environment file for HMR. If you already have a project just proceed from here.īy default, an Angular project is created by two environment files for development and others for production. Now we have an Angular project ready to implement HMR feature. # ? Which stylesheet format would you like to use? CSSĮnter the project directory $ cd angular-hmr-app # ? Would you like to add Angular routing? Yes Run following ng command to create a new Angular project $ ng new angular-hmr-app You can skip this step if already have an Angular project up and running. Let’s start by creating a new Angular project. Check more details on official Webpack docs. To implement the HMR feature in the Angular project, we create a separate environment file then enable it by making a few changes in the initializing files. Hot Module Replacement (HMR) is a Webpack feature to update the application modules without reloading and repainting everything.īy using the HMR technique the application development becomes faster as fewer resources are loaded after saving the changes in the project. Next, the unit and e2e tests are run in the build process, so the build will fail if the tests do not succeed.5) Conclusion What is Hot Module Replacement (HMR)? Multi-stage builds in Docker blog post for more info on multistage builds. In other words, the only thing kept from the first image is the compiled distribution code.Ĭheck out the Builder pattern vs.

This produces a lean, production-ready image. The temporary build image is discarded along with the original files, folders, and dependencies associated with the image. # prod # base image FROM nginx:1.16.0-alpine # copy artifact build from the 'build environment' COPY -from=build /app/dist /usr/share/nginx/html # expose port 80 EXPOSE 80 # run nginx CMD įirst, we take advantage of the multistage build pattern to create a temporary image used for building the artifact – the production-ready Angular static files – that is then copied over to the production image. # generate build RUN ng build -output-path =dist app # run tests RUN ng test -watch = false RUN ng e2e -port 4202

Try making a change to the AppComponent’s template ( src/app/) within your code editor. Open your browser to and you should see the app.

Finally, -rm removes the container and volumes after the container exits.

p 4201:4200 exposes port 4200 to other Docker containers on the same network (for inter-container communication) and port 4201 to the host.įor more, review this Stack Overflow question. You should now be able to remove the local “node_modules” flavor.

Since we want to use the container version of the “node_modules” folder, we configured another volume: -v /app/node_modules.

See this Stack Overflow question for more info. $ docker run -v $ may not work on Windows.
