nodejs-code-challenge-framework

nodejs-code-challenge-framework is a mini server and test environment for debugging and solving various coding challenges.

Structure

• servers → contains the Express server app.
• scratchpad → a workspace for testing code and running small functions.

Onboarding

Install dependencies:

yarn install

Node version

This project is designed to run on Node.js >= 22.

Running the project

Debug Scratchpad

I usually write in this project as a quick scratchpad to test and debug functions.
It’s especially convenient with VSCode Debug:

• Open the scratchpad.ts file.
• Write the code or function you want to test.
• Set breakpoints if needed.
• Run using the Debug Scratchpad configuration in VSCode.
• Quickly inspect outputs, variables, and behavior without setting up a full project.

This makes it very fast to experiment with ideas or verify code snippets.

Run server from the terminal

yarn build
yarn start

Run server in debug mode

Use the VSCode Debug server (with auto restart) debug command.

Tests

Tests are located inside the TESTS folder.

Run tests using the terminal

yarn test
# or
yarn test:coverage

Run tests in debug mode

Use the VSCode Debug Jest Tests debug command.
