NextJS Setup

---

Create a workspace and initial application

You develop apps in the context of an NextJS workspace.
To create a new workspace and initial starter app just follow the below steps

1. Run the command , as shown below

          npx create-next-app my-app
          
If you want to create an single-page project in NextJs, you need to install the necessary NextJs as below
           
This new command prompts for the information about features to include in the initial app. Accept the defaults by pressing the Enter 
  or Return key.
          
The NextJS installs the necessary NextJs 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 NextJS 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 run dev
          

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

Nowa-Setup

---

If you have already download and install node.js and NextJs then ignore prerequisites.

Prerequisites

Node.js

Download latest version of node.js from nodejs.org.
Install Node.js using downloaded file.
To check your node version, run node -v in a terminal/console window (cmd)

NextJs

To install the NextJs using npm, open a terminal/console window and run the following command.

          npm install 
          (or)
          yarn install 
          

Setup an NowaTemplate by

1. Download the Nowarar/zip file.
2. Extract it and then go in to Folder here you will see a NowaFolders
3. For Example
4. Here, I'm Choosing NextJs-file.
5. Now from a terminal window, navigate to the directory containing your application

Nowa/NextJs-file>

6. You can import all dependency by installing npm command

          npm install
          (or)
          yarn install

7. Now you are in stage to successfully run Nowausing below command:

          npm run dev
          (or)
          yarn run dev
          

Once you serve your application by default it will take their default port using 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 run build
          (or)
          npm run build
