Step 1
This document covers npm installation. Install the dependencies using:
npm install # OR yarn install
Installing with npm may require the use of the --legacy-peer-deps flag for some versions of npm.
In the new version of npm (v7), by default, npm install will fail when it encounters conflicting peerDependencies.
Take a look here for more info about peer dependencies in npm v7.
The differences between the two are below –
--legacy-peer-deps: ignore all peerDependencies when installing, in the style of npm version 4 through version 6.
--strict-peer-deps: fail and abort the install process for any conflicting peerDependencies when encountered. By default, npm will only crash for peerDependencies conflicts caused by the direct dependencies of the root project.
--force: will force npm to fetch remote resources even if a local copy exists on disk.
Step 2
Run the development server:
yarn start # OR npm run start
Step 3
Open http://localhost:3000 with your browser to see the result (if it doesn’t open automatically).
Now you can start editing pages or components. The page auto-updates as you edit and save a file.
To avoid any issues, please make sure you have the latest stable version of Node.js installed.
If you need to have multiple versions of Node.js installed, you can use nvm.
