Create a react app with bun

#react #bunjs #webdev #javascript

Want to use bun for your next react projects?

Install `bun`

First run the following command to check bun is installed or not

bun -v

If you don't have bun installed then run the following command to install bun

curl https://bun.sh/install | bash

Create a react app

Now run the following command to create a react app

bun create react [your-app-name]

It will create a new directory with the name of your app. To start the app run the following command

cd your-app-name
bun dev

Build production bundle for react app

By default bun does not ship with react-scripts so you need to install it first.

bun a react-scripts -d

Here we install it as a dev dependency.

Then run the following command to build the production bundle

bun react-scripts build

When you run the command above it will build the production bundle and it will be stored in the build directory.

Adding `scripts` to your package.json

We can add the following scripts to our package.json file

{
  "scripts": {
    "start": "bun dev",
    "build": "react-scripts build"
  }
}

Now we can run the following command to start the app

bun start

And we can run the following command to build the production bundle

bun run build

Bonus:

By default bun creates react app with javascript but we can easily use typescript by changing the file extension from .jsx to .tsx

Great article.

Does bun support other frameworks(I have svelte in mind) too?

Thanks again.

Ashirbad Panigrahi • Jul 17 '22

It is supports nextjs, react but I'm not sure about svelte but I will definitely look into it.

Pandademic • Jul 17 '22

Thanks!

bun is on my „try next“ list. But i don’t understand why all package manager needs this „run“ word.
I want to execute scripts like:

bun dev
bun start
bun build
…

Juliano Rafael • Jul 21 '22

the reason is to avoid clashes or confusion with the cli commands. if you had bun dev, just by looking at the command you don't know if it's a command from the cli itself or a script from the package.json. with run you know what's a script and what's a cli command.

Indeed

Ashirbad Panigrahi • Jul 20 '22

Yes I also want to see this, but for now you can use some certain commands in this way ex:

bun start

Khushi • Jul 17 '22

Ashirbad Panigrahi • Jul 17 '22

Happy to hear it

msbala007 • Aug 11 '22

Could I use npm packages?

Ashirbad Panigrahi • Aug 13 '22

Yes you can ex:

bun add @ashirbad/js-core

Hamid Abdulmalik Al-Hassan • Aug 13 '22

This is really great, how about bun for Vite? Once again, thank you.

nuralam • Sep 11 '23

why this happened?

Harry • Sep 18 '23

Since bun can directly execute .ts and .tsx files we can use the typescript template to setup a typescript project instead of js:
bun create react-app my-app --template typescript
