- We’ve seen how to install and configure react-native to develop the app on Mac. Also, We’ve created the app by React Native CLI and executed it to check the environment is configured well. Now, we are ready to develop the app with react-native. Let’s dive to the react-native development world!
- So using this tutorial you can complete your first task to install Install React Native on MAC ( MACINTOSH ) system and create your first React Native project and run that project in real iOS device or iOS emulator. If you use windows system then you can also read my this tutorial. So lets get started ?. Install Homebrew.
Creating a React App Introduction. React is a user interface framework developed by Facebook. It has a quickly growing developer adoption rate and was ranked as the most loved web framework in the 2019 Stack Overflow developer survey.This article will walk you through setting up your first React app and assumes you are familiar with text editors and command line navigation.
In this tutorial, we will learn how to deploy a React app with a back-end API to Vercel. We will cover deploying Lambda Functions API to interact with the React front-end.

I have written two other tutorials where we will deploy the same app to Netlify and Heroku. (Links below)
Let’s get started
Our React app will be very basic in nature, it calls Lambda Functions API with only one
POST
route and one GET
route.The
GET
route returns “Hello from Lambda Functions” and the POST
route is just one field that when posting, it returns “I received your POST request. This is what you sent me: [from input]”.The app also has client side routing with React Router that navigates to a secondary page and displays a 404 page when we enter a URL that does not exist. https://wirelessbrown320.weebly.com/blog/best-file-compression-app-mac.
Below you can see the demo app.
Upon loading, React calls the
GET
endpoint and displays a message. When submitting the single field form, React calls the POST
endpoint and displays a message.The React app was bootstrapped with Create React App (CRA), so the directory structure is pretty standard with the source files under the
src
directory and public assets under the public
directory.Deployment to Vercel
Vercel deploys your applications globally and puts them in front of CDNs. They also take care of your static assets component libraries and APIs. If using CI (Continuous Integration), Vercel only re-builds the part of your application that has changed.
You can head over to Vercel and create an account or log in.
Can i delete mail app from mac. Before starting, you will need to install Vercel CLI globally and then log in using the tool.
To install, type the following
And to log in
The tool will ask you to enter your email and then send you a confirmation
React with Lambda Functions
Take a look at the repo under the vercel-functions directory.
We have the React app right under the
root
directory and an api
directory with our functions.Lambda Functions
![Globally Globally](/uploads/1/3/4/1/134120460/859127554.png)
Under the
api
directory, we have two files: hello.js
and world.js
, each corresponding to a single lambda function. Both functions look pretty similar and the way Vercel distinguishes between a POST and a GET is the way they are called within React, with either a POST or GET request.hello.js
(GET)world.js
(POST)React App
This is how we call the API in our React app
Create React App Update
To run the app locally, you will have to use the Vercel CLI as follows
When you run the command for the first time, Vercel will guide you through a series of steps. Follow them to link or create a new project on your Vercel dashboard. The command will also run your React app, so no need to start React with yarn or npm.
Deploying to Vercel
Now we are ready to deploy the app. All you have to do in your terminal is to type the following
After Vercel finishes deploying, it will give you a URL where you can preview the app. The Inspect URL will take you to the deployment overview on your dashboard.
Link to the deployed app: https://create-react-app-functions.esausilva.vercel.app/
Vercel is all about zero-configuration deployment, but if you are in need of some advanced configurations, take a look take a look at their docs.
React with Express.js (Deprecated)
Take a look at the repo under the vercel-express directory.
As of April of this year, Vercel used to be called Zeit Now and with this re-branding they favor Functions over an Express.js app. Steps here are for historical purposes. Mac unable to uninstall apps windows 10.
We have the React app right under the
root
directory and an api
directory with the Express.js app.Below is an extract from the Express.js code showing both routes.
I decided to include client-side routing because Single Page Applications (SPAs) utilize the history API and when deployed, we need to include some “extra” steps. https://wirelessbrown320.weebly.com/blog/mac-run-app-from-terminal-without-hanging-terminal. (Hint: we need to configure redirects)
Let’s say we deploy the app to demoapp.com. When we hit demoapp.com the app loads. Then we click “Another Page (demoapp.com/another-page)” menu link, and the page loads fine; but if we refresh the page we receive an error. That is because the server is looking for a file named “another-page”, but that file does not exist since our entire app (including routing) is being loaded from
index.html
. So somehow we need to tell the server to redirect all of the requests to index.html
.I will point that exact step in each of the deployments to correct this “issue”.
Required Configurations
If you fiddle through the Express.js code, you will notice it is set to start on port
5000
, and if you have worked with CRA before, you know the React app will start on port 3000
. So in order for React to call the API and not get a CORS issue, we will need to configure a proxy. Luckily for us the React team made it super easy to add a proxy to CRA.Open
package.json
(under the root directory) and notice the below lineWith this line we are telling CRA to proxy our API requests through port
5000
.The above proxy is only required for local development.
One more thing to note in
package.json
file is the following scriptWith this script, we are instructing Vercel to use
react-scripts
to build our React app for production and then rename the build
directory to dist
directory which Vercel identifies as the directory to serve.One particular feature of Vercel is that it builds on the Vercel servers, instead of just pushing built code to their servers.
In order to deploy to Vercel, we need to create a configuration file named
vercel.json
at the root of the project. Let’s take a look at the contents of this file.Let’s break the file down:
In the first line we are telling Vercel to use version 2 of the Vercel platform and the name of the project. Line 2 is very important if you set it to
true
, then your source files will be publicly accessible, so set it to false
if you don’t want that behavior.Under the
builds
entry we are specifying how to run the React app and the Express.js app.@now/static-build
takes a package.json
file, installs all of its dependencies and runs now-build
npm script. In our case it will build the React app.@now/node-server
takes our Express.js app and wraps it inside a lambda. We also specify the path to the Express.js app.Install Create React App Globally Macos
Under the
routes
entry, we specify the different routing our setup will need. The first line we redirect calls coming from /api/*
to Express.js. Second line serves the static files. And the third line is for client routing (i.e. React Router), which redirects everything to index.html
.If you want to know more configuration options, take a look at the docs.
Bonus
Instead of manual deployments, Vercel integrates very nicely with Git. They support GitHub, GitLab, and Bitbucket. (Docs)

Conclusion
In this article, we learned how to deploy a React app with Lambda Functions API to Vercel. If you also read my other React Production tutorials, now you have the tools to deploy not only to Vercel but to Heroku and Netlify as well.
By learning how to deploy to multiple providers, you will be able to make an informed decision when it is time to deploy your project to production.

We're going to be using the command line on your local machine to build your first React app. To do this, you're going to have to install Nodejs, and a few libraries, if you don't already have them.
Installation instructions may seem boring, but just follow them as listed, and you should be fine!
Nodejs
First off, the perpetually-popular Nodejs!
Go to the package-manager install page for node.js, select your operating system, and follow the instructions to download and install Nodejs on your computer.
After you've done that, make sure that Nodejs is running on your system. Depending on what kind of machine you are using, you may need to open a new terminal window, or re-source your shell. You'll know you've got it working if you can type
Install Create React App Globally Macbook
at the prompt and get a list of commands and their descriptions! ✅
Installing Yarn
Yarn is a package manager for Nodejs. Were going to use it install create-react-app and get ourselves set up with a working React application.
Go to the installation page for the yarn project and select the tab for your operating system. Follow the instructions there to install Yarn on your machine.
Installing create-react-app
Now that that's out of the way, we can get back to React. With Yarn installed, run
from your command line.
To test that its working, run
and make sure that it shows you a list of commands and instructions for using them.
If you don't see the expected output, something went wrong somewhere along the way, and you may need to get help setting up your environment. If so, don't be afraid to ask for help!
Managing your local environment is a complex task fraught with gotchas, and is a skill all on its own.
Create a React app!
Once you have create-react-app installed and working, think of a name for your app and run
This should produce a long stream of output, beginning with a message like
and ending with a success message and instructions for serving your new React app.
Install Create React App Windows
You should see a list of files output. If you inspect your file system you should now see the contents of your brand new react app! In the next section we'll take a look at these generated files.
Ta-da, you're done with the install process!
