TypeScript Kata Template

To install dependencies

yarn

To run all tests

yarn test

To run all tests each time you save a change

yarn test --watchAll

To type-check and lint (in vscode)

ctrl-shift-b (or on mac, cmd-shift-b)

Debug in vscode

Call the function you want to debug from src/main.ts

Add a breakpoint in your function by clicking to the left of the relevant line number.

Open the "run and debug" panel

From the top choose "Debug main.ts"

That's it, the debugger should launch and pause when your first breakpoint is encountered.

This will compile your code before running, and will show you the typescript source even though in reality the debugger is stepping through the relevant compiled javascript. It is able to do this because tsconfig specifies sourceMap: true and an ourDir location.

If you're curious you can see the specific details in ./vscode/launch.json

To compile for codewars

Some codewars katas support typescript. Others only support JS submissions.

Here's how to compile one stand-alone .ts file into .js for the latter type of kata.

You will first need to alter make-js-for-one in package.json to refer to the file you want compiled.

then:

yarn make-js-for-one

your output .js will be generated into a new folder generatedJS.

⚠️ Delete this folder when you're done to avoid confusion!

alternatively, use tsc directly

You don't need to use the make-js-for-one convenience command. Instead:

yarn tsc src/myGreatFile.ts --outDir generatedJS

but you might get tired of typing that!
