> Compared with the old `UI`, it will be more standardized, and it will also have a more complete type checking mechanism. At the same time, its speed has made a qualitative leap.
To do this you need to change the `VITE_APP_DEV_WEB_URL` parameter variable in `.env.development` in the project root directory.
It is worth noting that when you do not change the request path or route, you only need to write `http`, `ip` and `port` without the `/` symbol at the end, such as `http://127.0. 0.1:12345`.
When you are ready to package, you need to modify the `VITE_APP_PROD_WEB_URL` parameter in `.env.production` accordingly to ensure that the packaged file can be normally requested to the backend service address.
In order to ensure the stability of the project, we have added a lot of `E2E` tests, you can learn about it through the following list, and when you make code changes, please make sure that the `DOM` of `E2E` has not changed, if there are changes, please Correspondingly modify the backend code or explain it in `PR`.
Since this system is newly developed, there are some known issues, but this does not affect your use. We will deal with it in subsequent versions. If you are an open source enthusiast, your contributions are very welcome.
