Vercel deployment (default) in NextJS - Step-by-Step Execution

Concept Flow - Vercel deployment (default)

Write Next.js app

↓

Run 'vercel login'

↓

Run 'vercel --prod'

↓

Vercel detects Next.js project

↓

Vercel runs build command

↓

Build succeeds?

No→Show error logs

Yes↓

Vercel deploys app

↓

App is live with URL

↓

User visits deployed app

This flow shows how your Next.js app goes from your computer to a live website on Vercel using default deployment steps.

Execution Sample

NextJS

vercel login
vercel --prod

These commands log you into Vercel and deploy your Next.js app to production with default settings.

Execution Table

Step	Action	System Response	Result
1	Run 'vercel login'	Prompt for email and password	User logged into Vercel CLI
2	Run 'vercel --prod'	Detect Next.js project	Start build process
3	Build runs	Compile Next.js app	Build succeeds
4	Deploy app	Upload files to Vercel servers	App deployed and URL generated
5	Visit URL	Browser loads app	App is live and interactive

💡 Deployment completes when app is live and accessible via generated URL

Variable Tracker

Variable	Start	After Login	After Build	After Deploy	Final
User Auth	Not logged in	Logged in	Logged in	Logged in	Logged in
Build Status	Not started	Not started	Success	Success	Success
Deployment URL	None	None	None	https://your-app.vercel.app	https://your-app.vercel.app

Key Moments - 3 Insights

Why does Vercel need to detect the Next.js project before building?

Vercel uses the detection step (see execution_table step 2) to know how to build your app with the right commands and settings automatically.

What happens if the build fails during deployment?

If the build fails (execution_table step 3), Vercel stops deployment and shows error logs so you can fix issues before trying again.

How do you access your deployed app after deployment?

After deployment (step 4), Vercel gives you a URL (see variable_tracker Deployment URL) where your app is live and can be visited in a browser.

Visual Quiz - 3 Questions

Look at the execution table, what is the system response after running 'vercel --prod'?

A Upload files to Vercel servers

B Prompt for email and password

C Detect Next.js project

D Browser loads app

💡 Hint

Check step 2 in the execution_table for the system response after 'vercel --prod'

At which step does the build succeed in the deployment process?

A Step 1

B Step 3

C Step 2

D Step 5

💡 Hint

Look at the 'Build runs' action and its result in the execution_table

If the build failed, what would you expect to see according to the concept flow?

A Show error logs

B Upload files to Vercel servers

C App is live and interactive

D Prompt for email and password

💡 Hint

Refer to the decision branch after 'Build succeeds?' in the concept_flow

Concept Snapshot

Vercel deployment (default):
1. Login with 'vercel login'
2. Deploy with 'vercel --prod'
3. Vercel auto-detects Next.js
4. Runs build and deploys if successful
5. App is live at generated URL
Use default commands for quick deployment.

Full Transcript

This visual execution shows how to deploy a Next.js app on Vercel using default settings. First, you log in with 'vercel login'. Then, you deploy your app with 'vercel --prod'. Vercel detects your Next.js project and runs the build. If the build succeeds, Vercel deploys your app and gives you a URL. You can visit this URL to see your live app. If the build fails, Vercel shows error logs so you can fix issues. Variables like user authentication, build status, and deployment URL change step-by-step during this process.
