DeployingNestjsWithNowshServerless (vercel) is a free web application hosting platform that supports serverless functions features, runs nodejs servers, deploys static websites, server-side ssr-rendered websites, and supports file storage (/ tmp directory). The following example deploys nestjs to vercel:


sudo npm i -g now

# 登陆
now login # 会提示打开vercel操作

Create a now configuration for your Nestjs application

Create a now.json file under the nestjs project directory Name is an application name that is used for management. Other configurations remain the same.

  "version": 2,
  "name": "nest-api-analyse-imports",
  "builds": [
      "src": "dist/main.js",
      "use": "@now/node"
  "routes": [
      "src": "/(.*)",
      "dest": "dist/main.js"

Deploy Nestjs applications to vercel

yarn build && now

Note that the Inspect link is the status of the current project on the vercel. After successful deployment, the output of a Preview link is the application access portal. Example: Nest-api-analyse-imports

Be careful

Only the / tmp directory of the file system in the vercel environment is readable and writable, and the rest is read-only.

Automate deployment using Github Action

You need to configure a vercelToken: ZEIT_TOKEN

name: Deploy-Server
      - 'v*.*.*'
    runs-on: ubuntu-latest
      - name: Checkout
        uses: actions/checkout@v2

      - name: Install Deps
        run: yarn add now

      - name: Deploy
        run: yarn build && now -c --token ${{secrets.ZEIT_TOKEN}}

What can it be used for?

  1. Deploy your own nestjs server and provide various micro-service interfaces
