The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s.The technique uses a timer to break down work into intervals, traditionally 25 minutes in length, separated by short breaks last 5 minutes. Each interval is known as a pomodoro, from the Italian word for 'tomato', after the tomato-shaped kitchen timer that Cirillo used as a university student.

想让大家能在线上看到前端页面，使用Github pages是很好的选择！ 部署上参考了文章如何部署create-react-app项目到Github pages步骤,为了方便自己查阅，在此做简单的总结：

1.打包编译、提交代码到 github 远程仓库

npm run build

git add .
git commit -m "test gh-pages"
git push origin master

2.生成gh-pages分支

git subtree push --prefix=build origin gh-pages

In the project directory, you can run:

Runs the app in the development mode.
Open https://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.

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

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.

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.
