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 “$IP_ADDRESS” with your own ip address.

   {
       "/api/*": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "changeOrigin": true,
           "logLevel": "debug"
       },
       "/service/*": {
           "target": "$IP_ADDRESS",
           "secure": false, 
           "logLevel": "debug"
       },
       "/c/login": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/sign_in": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/c/log_out": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/sendEmail": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/language": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/reset": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/userExists": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/reset_password": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/i18n/lang/*.json": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug",
           "pathRewrite": { "^/src$": "" }
       },
       "/chartrepo": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "logLevel": "debug"
       },
       "/*.json": {
           "target": "$IP_ADDRESS",
           "secure": false,
           "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.
