⚛️ Local HTTPS for React app in Nx workspace

nightbr profile image Titouan B ・3 min read

Hey, welcome back in this post series where we will see how to setup a full HTTPS development environment.

In this post, we will setup local HTTPS for React app in Nx workspace.

If you don't have generated your certificate with mkcert, I recommand you read the first post of this series. → link

What is Nx?


Nx is a set of extensible dev tools for monorepos, which helps you manage your projects at any scale. It provides great integration with major framework such as Angular, React, Nestframework, Express, ionic, ...

💡 Nx use the angular-cli under the hood!

Setting up the project workspace

Creating a new empty workspace

$ npx create-nx-workspace
npx : 179 installé(s) en 7.547s
? Workspace name (e.g., org name)     myorg
? What to create in the new workspace empty             [an empty workspace with a layout tha
t works best for building apps]
? CLI to power the Nx workspace       Nx           [Recommended for all applications (React, 
Node, etc..)]

🗒️ If you already have an Nx workspace, you can skip these steps.

Then, we will install the Reactjs schematics:

npm install -D @nrwl/react

Now, we will generate a new Reactjs application called react-app (change the name with your app name).

nx generate @nrwl/react:application --name=react-app

Choose your settings such as stylesheet format, routing, ...

Start serving your app with nx serve react-app 🎉


🗒️ Look at the Reactjs Nx plugin documentation to see more options → here

Setting up HTTPS

From the first post of this series, I will assume that you have generated your certificate at location myorg/dev-stack/certs/local-cert.pem & myorg/dev-stack/certs/local-key.pem. Don't hesitate to go back to the first post to use mkcert and generate your certificate.

In the workspace.json, search for your app name (here react-app). Under this, look for the serve object and options. We will add the ssl configuration under "browserTarget": "react-app:build",.

The serve object in the workspace.json should look like this:

    "serve": {
          "builder": "@nrwl/web:dev-server",
          "options": {
            "buildTarget": "react-app:build",
            "host": "dev.local",
            "ssl": true,
            "sslKey": "./dev-stack/certs/local-key.pem",
            "sslCert": "./dev-stack/certs/local-cert.pem"
          "configurations": {
            "production": {
              "buildTarget": "react-app:build:production"

Now save and serve the app:

$ nx serve react-app

> nx run react-app:serve

You can open https://dev.local:4200 which is secured with a valid certificate 🔐🎉



Feel free to change any configuration on the options, but don't forget to regenerate a new certificate with mkcert of you change the domain name ⚠️

See you in the next post!

This project was generated using Nx.

🔎 Nx is a set of Extensible Dev Tools for Monorepos.

Adding capabilities to your workspace

Nx supports many plugins which add capabilities for developing different types of applications and different tools.

These capabilities include generating applications, libraries, etc as well as the devtools to test, and build projects as well.

Below are our core plugins:

  • React
    • npm install --save-dev @nrwl/react
  • Web (no framework frontends)
    • npm install --save-dev @nrwl/web
  • Angular
    • npm install --save-dev @nrwl/angular
  • Nest
    • npm install --save-dev @nrwl/nest
  • Express
    • npm install --save-dev @nrwl/express
  • Node
    • npm install --save-dev @nrwl/node

There are also many community plugins you could add.

Generate an application

Run nx g @nrwl/react:app my-app to generate an application.

You can use any of the plugins above to generate applications as well.

When using Nx, you can create multiple applications and libraries in the same workspace.

Generate a library

Run nx
