☁️ Salesforce LWC TodoMVC example. Great way to start your SF LWC project. This guide implements full-featured example from todomvc.com and using almost all features from LWC like modules, composition, reactivity, events, component lifecycle events and even test example.
Start this project if you like it ⭐
No need to setup any salesforce external environments!!! Start building full-featured LWC components locally without overhead.
Start simple by running yarn watch (or npm run watch, if you set up the project with npm). This will start the project with a local development server.
The source files are located in the src folder. All web components are within the src/modules folder. The folder hierarchy also represents the naming structure of the web components.
Find more information on the main repo on GitHub.
