lwc-build-utils

Scripts to run a Lightning Web Components (LWC) project

Usage

To use these utils, you must first create a Lightning Web Components project.

$ heroku plugins:install heroku-lwc-plugin
$ heroku lwc:create
$ cd <app_name>

To run the project in development mode, run the below command. This command uses lwc-build-utils to create the necessary assets like wire adapters, service workers, server scripts and more. It then runs the project locally, and watches the files for any changes and reloads the browser to reflect the changes.

$ npm run watch

To run the project in production mode, run the following commands

$ npm run build
$ npm run start

When deploying this project to Heroku, just commit the changes to the Heroku GIT Remote endpoint that automatically gets created when you run the heroku lwc:create command.

$ git add .
$ git commit -m "first commit"
$ git push heroku main

Heroku automatically runs the build and start scripts.
