Typescript 4 Design Patterns and Best Practices

This is the code repository for Typescript 4 Design Patterns and Best Practices, published by Packt.

How to run the code examples?

To be able to run the examples, you first need to install all the required dependencies using the following command:

npm install

We have configured a local version of ts-node and Typescript so you don't have to install globally.

If you have compatible TypeScript compiler installed globally, you can just use the global ts-node command to run target code bundle.

You can then run the ts npm task providing the relative path of the script:

npm run ts -- chapters/smoke.ts
> ts-node "chapters/smoke.ts"
1
2
3
4
Hello
1

Alternatiely you may want to build and run the compiled javascript from the dist folder:

npm run build
> npx tsc --build chapters

node dist/smoke.js
1
2
3
4
Hello
1

In some cases you may want to quickly see the compiled javascript or to quickly test some examples using the TypeScript Playground. You can copy the code in the playground (left) to get the resulting JavaScript output (right)
