Format the code with Prettier

We are using Prettier as code formatter. You only need to run yarn format to write the formatted code with Prettier. If you want to check if the code is well formatted run instead: yarn format-check

Build

If you make changes to the code, run these commands to build the distribution libray, install all the dependencies with:

yarn --include=dev i

For a development build, that is the code will be rebuilt for every changes, run:

yarn dev-ts

Instead for a production build, with more optimizations in the code and smaller size, run:

yarn build-ts
