Prerequisites

Packages to be installed on a global level

1. Install Node.js (version >= v12.18.1 );
2. Install yarn package management tool globally;

$ npm install -g yarn

Project dependencies installation

In the project directory, execute the following command:

$ yarn install

Development

Start the development environment

For the purpose of developing new features, testing the changes, as well as the TS compilation, project has a sandbox file, which you can modify and save, and after that the source code would be re-compiled and executed.

To do so, first, in the project root directory execute this command, and wait for the console log output to appear.

$ yarn start

Then, modify src/run.ts file, and save it, so the code would be re-compiled, executed and re-rendered in the output.

Testing

For the sake of consistency, all the tests should be created with .spec.ts extension, at the same level, where the tested file is located.

For example, for src/utils.ts the test file should be named as src/utils.spec.ts.

To run the tests, in the project root directory execute this command, and wait for the console log output to appear.

$ yarn test

Code quality

With the idea of following good practices and standards, code should be linted and cleaned-up before being commited. The project is configured to use eslint and prettier for this purpose.

To run the linting, in the project root directory execute this command, and wait for the console log output to appear.

$ yarn lint

Typing with *.d.ts

The project is configured in such as way, so there is no need to manually create types. After running build command, all the types are generated automatiacally, based on .ts files annotations.

Build

Execute the following commands in the project directory to build resources for execution in the production environment.

$ yarn build

Compiled bundles as well as the exported types, would be located in "root directory/dist"
