Elevate your software design skills with practical examples and insightful discussions. This workspace has been generated by Nx, Smart Monorepos · Fast CI. For each design pattern, there is folder based on TypeScript. If you are comming from another programming language world, don't worry. They are not complicated. Also, tests are included for each pattern. Also you can see bad practices to understand use cases.

You can open directory, for instance:

$ cd app/strategy-pattern

There is a README file that you can review first.

Here is some steps in each README file:

• 💡 Use Case: a short description about the specific problem that we want to solve.
• ❌ Bad Practice: a typical solution that works but not in a proper way.
• ✅ Good Practice: implementing the specified design pattern to solve the problem in a proper way.

Diagram: There is also a diagram to represent the oveview of the design pattern to understand better. These are some examples:

Open /app folder to see all design patterns. ✅

In the root directory, run:

$ npm install

To run the design pattern:

$ npm run -w PATTERN_NAME start

For instance PATTERN_NAME can be strategy-pattern

To run the bad practice:

$ npm run -w PATTERN_NAME start:bad

In order to run tests, run the following command. (add :watch to run it in watch mode):

$ npm run test

Run the following command to evaluate test coverage:

$ npm run test:cov

To see the coverage report, just run:

$ npm run test:cov:open
