This project was bootstrapped with Create React App.
Below you will find some information on how to perform common tasks.
You can find the most recent version of this guide here.
Folder Structure
After creation, your project should look like this:
my-app/
README.md
node_modules/
package.json
public/
index.html
favicon.ico
src/
asserts/
logo.svg
components/
App.test.tsx
App.tsx
styles/
font/
...Roboto Font Files
sass/
_app.scss
_font.scss
index.scss
index.tsx
Available Scripts
In the project directory, you can run:
npm start
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
npm test
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
npm run build
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
npm run eject
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
Supported Browsers
By default, the generated project uses the latest version of React.
You can refer to the React documentation for more information about supported browsers.
Visual Studio Code
You would need to have the latest version of VS Code and VS Code Chrome Debugger Extension installed.
Then add the block below to your launch.json file and put it inside the .vscode folder in your app’s root directory.
{
"version": "0.2.0",
"configurations": [{
"name": "Chrome",
"type": "chrome",
"request": "launch",
"url": "http://localhost:3000",
"webRoot": "${workspaceRoot}/src",
"userDataDir": "${workspaceRoot}/.vscode/chrome",
"sourceMapPathOverrides": {
"webpack:///src/*": "${webRoot}/*"
}
}]
}Note: the URL may be different if you've made adjustments via the HOST or PORT environment variables.
Start your app by running npm start, and start debugging in VS Code by pressing F5 or by clicking the green debug icon. You can now write code, set breakpoints, make changes to the code, and debug your newly modified code—all from your editor.
