FEATURE: Config option to automatically import emulator data on start

[Soviut]

Problem

I would like to import existing data into the Firebase emulators on start. Currently, there is no option in vite-plugin-firebase to do this.

Details

Local emulator data can be exported while the emulators are running with

npx firebase emulators:export <dir>

You can then import the data when the emulators start with

npx firebase emulators:start --import=<dir>

Solution

Add a config option that allows the import directory be specified. If the option exists, perform the import.

firebasePlugin({
  projectName: 'whatever',
  projectId: 'whatever-12345',
  targets: ['firestore', 'functions', 'storage'],
  showUI: true,
  importPath: './data' // <--
}),

Workarounds

You can import while the emulators are running with the following, but it's inconvenient to have to always run two commands.

npx firebase emulators:exec --import=<dir>
