Installation

React Setup

---

Create a workspace and initial application

You develop apps in the context of an React workspace.
To create a new workspace and initial starter app:

1. Run the command React new and provide the name filename as my-app, as shown below

npx create-react-app my-app

2. The npx command prompts is use for the information about features to include in the initial app. Accept the defaults by pressing the Enter or Return key.

The React install the necessary React npm packages and other dependencies. This can take a few minutes. This creates a new workspaces and a simple Welcome app, ready to run.

Run the application

The React includes a server, so that you can build and serve your app locally.

1. Navigate to the workspace folder, such as my-app.
2. Run the following commands:

cd my-app
 npm start
                                     

The yarn or npm serve command launches the server, watches your files, and rebuilds the app as you make changes to those files. The start just Option automatically opens your browser to http://localhost:3000/.

Note

npm install

If your are using npm install, You have to delete the

yarn-lock file

(or)

yarn install

If your are using yarn install, You have to delete the

package-lock.json file

basically npm i is used to install all dependencies or devDependencies from a package. if there will be any dependencies which need to be installed but getting error message while installing, then --force will help to install those dependencies.

The --force argument will force npm to fetch remote resources even if a local copy exists on disk. It will be on a last-dependency-downloaded-wins basis and will overwrite any previously downloaded dependencies.

npm install --force

if there is peer dependency issues while installing
it will always skip peer dependencies (whatever those are) during installation even if there are no issues.

npm install--legacy-peer-deps

we have to use only one file example: (for yarn yarn-lock) & (for npm package-lock.json) file

Build Application

Build your application for host on server using below command:

yarn build
   (or)
npm run build
