Examples

To try these examples you need to have Node.js installed. Then clone this repo and follow the instructions in README.md in each subdirectory.

The last two examples require you to have Docker Desktop installed.

• 1-nodemon-example - This is the simplest possible example of using Nodemon for live reload of a Node.js JavaScript application.
• 2-nodemon-example-with-config - This is an example of using Nodemon for live reload of a Node.js JavaScript application, this time configuration is provided via the nodemon.json configuration file.
• 3-nodemon-example-with-typescript - This is an example of using Nodemon and ts-node for live reload of a Node.js TypeScript application.
• 4-automated-testing-example - This is an example of automated tests using Jest in "watch mode" so your tests automatically reload as you are changing your code.
• 5-automated-testing-with-typescript - This is an example of automated tests using Jest in "watch mode" so your TypeScript tests automatically reload as you edit your code.
• 6-frontend-with-parcel - This the simplest possible example of a frontend bundled with Parcel. Parcel has built in "live reload" you simply run it, then as you edit your code Parcel refreshes your browser to show the updated web page.
• 7-frontend-with-webpack - This the simplest possible example of a frontend bundled with Webpack. Webpack is a little tricky to configure, but you can enable the "webpack dev server" and then you have "live reload" with Webpack. As you edit your code the dev serfver refreshes your browser to show the updated web page.
• 8-docker-example - This is an example of running a Node.js JavaScript microservices under Docker with "live reload" enabled. The code on the development computer is automatically synchronized into the container and the application is automatically restarted by Nodemon as you edit your code.
• 9-docker-example-typescript - This is an example of running a Node.js TypeScript microservices under Docker with "live reload" enabled. The code on the development computer is automatically synchronized into the container and the application is automatically restarted by Nodemon as you edit your code.
