• React
• Redux for state management
• Redux-saga for asynchonous tasks
• Axios for api call
• Nextjs for server side render
• Scss
• Cypress for integration testing
• React-testing-library for unit test
• NX for monorepo management

Some coding convention:

• Use create-react-app for create react app
• Import scss file direct from component (I don't use css module because usually I want to override css of library)
• Use Utility first approach tailwindcss.com/docs/utility-first
• Microfrontend for large projects
• Lazy load components and code splitting
• For page render large element, consider use React-window library for only render parts in screen.
• A component just do one job, keep it as small as possible.
• Have prettier and eslint

My favorite UI library: Antd, Tailwindcss

Some technologies trying:

• Graphql
