# Dolphin Scheduler UI Next --- > After two and a half months of development cycle, we have brought a brand-new `UI` management system (V1.0.0-Alpha). > > 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. > > We also provide dark mode and light mode to meet the preferences of different developers. It will make your eyes shine. > > If you have tried the new `UI` and found problems in use, you can contact us through issue. --- ### Start Using For the best experience, we recommend using `node 16.x.x` and `pnpm 6.x.x`. You can learn how to install the corresponding version from their official website. - [node](https://nodejs.org/en/) - [pnpm](https://pnpm.io/) #### Install Dependencies ```shell pnpm install ``` #### Start Development Project 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`. ```shell pnpm run dev ``` #### Build Project We provide two packaging and compilation environments by default, `development` and `production`. Their interface request configurations are in `.env.development` and `.env.production` in the project root directory respectively. Please change the `URL` is the address of the corresponding backend service. ```shell pnpm run build:dev # or pnpm run build:prod ``` ---
