# React homework template



This project was created with

[Create React App](https://github.com/facebook/create-react-app). To get

acquainted and configure additional features

[refer to documentation](https://facebook.github.io/create-react-app/docs/getting-started).



## Creating a repository by template



Use this GoIT repository as a template for creating a repository

of your project. To use it just tap the `«Use this template»` button and choose

`«Create a new repository»` option, as you can see on the image below.

The page for creating a new repository will open on the next step. Fill out

the Name field and make sure the repository is public, then click

`«Create repository from template»` button.

You now have a personal project repository, having a repository-template file 

and folder structure. After that, you can work with it as you would with any 

other private repository: clone it on your computer, write code, commit, and 

send it to GitHub.



## Preparing for coding



1. Make sure you have an LTS version of Node.js installed on your computer.

   [Download and install](https://nodejs.org/en/) if needed.

2. Install the project's base dependencies with the `npm install` command.

3. Start development mode by running the `npm start` command.

4. Go to [http://localhost:3000](http://localhost:3000) in your browser. This

   page will automatically reload after saving changes to the project files.



## Deploy



The production version of the project will automatically be linted, built, and

deployed to GitHub Pages, in the `gh-pages` branch, every time the `main` branch

is updated. For example, after a direct push or an accepted pull request. To do

this, you need to edit the `homepage` field in the `package.json` file,

replacing `your_username` and `your_repo_name` with your own, and submit the

changes to GitHub.



```json

"homepage": "https://your_username.github.io/your_repo_name/"

```



Next, you need to go to the settings of the GitHub repository (`Settings` >

`Pages`) and set the distribution of the production version of files from the

`/root` folder of the `gh-pages` branch, if this was not done automatically.

### Deployment status



The deployment status of the latest commit is displayed with an icon next to its

ID.



- **Yellow color** - the project is being built and deployed.

- **Green color** - deployment completed successfully.

- **Red color** - an error occurred during linting, build or deployment.



More detailed information about the status can be viewed by clicking on the

icon, and in the drop-down window, follow the link `Details`.

### Live page



After some time, usually a couple of minutes, the live page can be viewed at the

address specified in the edited `homepage` property. For example, here is a link

to a live version for this repository

[https://goitacademy.github.io/react-homework-template](https://goitacademy.github.io/react-homework-template).



If a blank page opens, make sure there are no errors in the `Console` tab

related to incorrect paths to the CSS and JS files of the project (**404**). You

most likely have the wrong value for the `homepage` property in the

`package.json` file.



### Routing



If your application uses the `react-router-dom` library for routing, you must

additionally configure the `` component by passing the exact name

of your repository in the `basename` prop. Slashes at the beginning and end of

the line are required.



```jsx



  



```



## How it works



![How it works](./assets/how-it-works.png)



1. After each push to the `main` branch of the GitHub repository, a special

   script (GitHub Action) is launched from the `.github/workflows/deploy.yml`

   file.

2. All repository files are copied to the server, where the project is

   initialized and linted and built before deployment.

3. If all steps are successful, the built production version of the project

   files is sent to the `gh-pages` branch. Otherwise, the script execution log

   will indicate what the problem is.
