If you already have a harbor backend environment, you can build a frontend development environment with the following configuration.

1. Create the file proxy.config.json in the directory harbor/src/portal，and config it according to the sample below.

   NOTE: You should replace “hostname” with an available Harbor hostname.

   [
     {
       "context": [
         "/api",
         "/c",
         "/i18n",
         "/chartrepo",
         "/LICENSE",
         "/swagger.json",
         "/swagger2.json",
         "/devcenter-api-2.0",
         "/swagger-ui.bundle.js"
       ],
       "target": "https://hostname",
       "secure": false,
       "changeOrigin": true,
       "logLevel": "debug"
     }
   ]
   

2. Open the terminal and run the following command，install npm packages as 3rd-party dependencies.

   cd harbor/src/portal
   npm install
   

3. Execute the following command，serve Harbor locally.

   npm run start
   

4. Then you can visit the Harbor by address: https://localhost:4200.
