This project has been developed with the last version of React.js and Redux (Redux toolkit).

• React.js
• Redux toolkit
• Typescript
• Cypress for E2E
• React testing library
• Prettier, ESLint, Husky
• Netlify and GithubAction for CI/CD automate testing

• DEMO URL

In the project directory, you can run:

Install all the dependencies that are needed for developing.

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

Cypress is a next-generation front-end testing tool built for the modern web. We address the key pain points developers and QA engineers face when testing modern applications. This command has been used to run the E2E test with Cypress. I have used cypress for E2E and mock data.

• This command builds the Dogstagram application for production.

• This command formats all files with Prettier.

• I have used several mythologies of clean code in this frontend project.
• I have used React Testing Library to test the redux reducer to test the main functionality of the Dogstagram application.
• I have isolated all folders for each functionality. I have used the API factory for HTTP requests. Helper, components, pages, interfaces, assets, and store that I have separated in isolated folders. For components, I have used S in SOLID principles, each component uses single functionality in Dogstagram.

Regarding the S for SOLID I just tried to keep each function(component as a function as well) just be responsible for a single task. That's why I just created a separate component for every part and also keep it simple stupid.

BEM has been used for methodology with SCSS format to create reusable components for this task. I have followed the structure developed in the dummy files.

Using Prettier for opinionated code formatter. It will take care of the formatting for you. Prettier creates an abstract syntax tree from your code and uses it to write new code formatted according to a set of rules. In addition, I check pretty before every commit by adding a pre-commit hook. For more detail check package.json, husky section.

Modern native Git hooks made easy. Husky is used for git hook pre-commit to format all code with Prettier.

yarn test

yarn cypress open

I have used GitHub actions for automated testing and run all Unit Test.
