tailwind-react-next.js-typescript-eslint-jest-starter

Starter template for building a project using React, Typescript, Next.js, Jest, TailwindCSS and ESLint.

Setup Instructions

1. Clone or download the project.
2. cd in the project directory.
3. If you cloned the project, make sure you remove the remote reference to this project by running git remote rm origin.
4. Copy .env.example to .env as that file is used to load up all your environment variables.
5. Run yarn install or npm install to install all dependencies.

Commands

• yarn dev: To start a local development server.

• yarn test: To run the entire unit test suite using jest.

• yarn test:ci: To run tests on CI.

• yarn lint: To run the ESLint based linter to find out the issues in the project.

• yarn format: To autoformat all the issues.

• yarn export: Run this after running yarn analyze to export a build copy.

• yarn production: To export a production build. Use yarn start to serve that.

• yarn upgrade --latest: To upgrade all packages to their latest versions (could include breaking changes).

Code Structure

All source code is located in the src/ directory.

1. All Next.js entrypoints are housed in the src/pages directory as a default.

   • Currently has _app.tsx which imports TailwindCSS.
   • There's also a sample index.tsx.

   NOTE: Feel free to move pages outside of src/ if that's what you prefer. You'll just need to restart your local development server and everything should continue working as normal.

2. src/components are all stateless reusable components.

3. src/css folder is there just to house any CSS.

   • Currently contains the TailwindCSS initialization CSS file.

4. All env variables are available in .env files (.env file isn't committed). Whenever you update .env, please update .env.example and .env.test and next.config.js to proxy all environment variables properly.

   • You can access these variables in the app source code anywhere using process.env.<VAR_NAME>.

If you feel like changing the directory structure, please change the appropriate settings in the following files:

• .swcrc
• jest.config.js
• postcss.config.js
• tsconfig.json
• The lint and the format scripts in package.json

Note

1. This project removes the x-powered-by response header via next.config.js by marking the poweredByHeader property as false.

2. If you wish to use Enzyme instead of React Testing Library, please refer to this commit. Enzyme was removed with that commit.

3. If you wish to use Babel instead of SWC (introduced with the Next.js v12 upgrade), please remove the .swcrc file and add a .babelrc file at the root with the following:

{
    "presets": [
        "next/babel"
    ],
    "plugins": [
        [
            "module-resolver",
            {
                "root": [
                    "./"
                ],
                "alias": {
                    "@src": "./src"
                },
                "extensions": [
                    ".js",
                    ".jsx",
                    ".ts",
                    ".tsx"
                ]
            }
        ]
    ]
}

Then, open ./jest.config.js and find the globals config. Add babelConfig: true, to it, like so:

{
    globals: {
        'ts-jest': {
            tsconfig: '<rootDir>/tsconfig.jest.json',
+           babelConfig: true,
            diagnostics: false,
        },
    },
}

Also, run yarn add -D @babel/core babel-plugin-module-resolver eslint-import-resolver-babel-module to install Babel's dependencies.
