angular-deploy-bunny

An Angular Architect builder that deploys your build output to a Bunny.net CDN Storage Zone with SHA256-based incremental sync, then purges the matching Pull Zone. Wire it up as your project's ng deploy target.

• Incremental — hashes every file with streaming SHA256 and only uploads what changed; orphaned remote files are deleted.
• Safe ordering — uploads first, deletes second. If an upload fails it aborts before deleting anything, so the live site stays consistent. Re-running converges.
• Cache purge — calls the Pull Zone purge API after a successful sync. A failed purge is a warning, not an error (the cache expires by TTL).
• No secrets in config — credentials come from environment variables or a gitignored .env.local.

Install

pnpm add -D angular-deploy-bunny
# or: npm i -D angular-deploy-bunny

Requires Angular 17+ using the esbuild-based application builder — the default since v17, which emits the browser bundle into a browser/ folder — and Node 22+. The test suite runs in CI against Angular 17 through 21.

Quick start

Add a deploy target to the project in your angular.json:

"deploy": {
  "builder": "angular-deploy-bunny:deploy",
  "options": {
    "buildTarget": "my-app:build:production",
    "storageZoneName": "my-zone",
    "storageRegion": "Falkenstein",
    "pullZoneId": 12345,
    "ignore": ["**/*.map"]
  }
}

Then deploy:

ng deploy                       # build + sync + purge
ng deploy --dry-run             # preview the diff, no network writes
ng deploy --no-purge-after-upload

With buildTarget set, the builder runs the Angular build first and syncs its /browser output folder automatically. If you'd rather sync a folder you already built, drop buildTarget and set outputPath instead.

Credentials

The builder never stores secrets in angular.json. It reads two environment variables, falling back to a .env.local file at your workspace root:

cp node_modules/angular-deploy-bunny/.env.local.example .env.local

BUNNY_STORAGE_PASSWORD=…   # Storage Zones → <zone> → FTP & API Access → Password
BUNNY_ACCOUNT_API_KEY=…    # Account → API → API Key (only needed for purge)

Add .env.local to your .gitignore. The BUNNY_ACCOUNT_API_KEY is only required when purgeAfterUpload is true (the default); if either secret is missing the build aborts before touching the network with a clear message.

Options

| Option | Type | Default | Notes | | ------------------ | ---------------- | -------------- | --------------------------------------------------------------------------------------------- | | storageZoneName | string | required | Name of the Bunny Storage Zone. | | buildTarget | string \| null | null | Angular build target to run first, e.g. my-app:build:production. If null, set outputPath. | | outputPath | string \| null | null | Folder to sync. Defaults to the build target's output + /browser. | | storageRegion | enum | Falkenstein | One of: Falkenstein, London, NewYork, LosAngeles, Singapore, Stockholm, SaoPaulo, Johannesburg, Sydney. | | targetFolder | string | / | Subpath inside the storage zone. | | pullZoneId | number \| null | null | Required when purgeAfterUpload is true. | | purgeAfterUpload | boolean | true | Purge the Pull Zone cache after a successful sync. | | concurrency | number | 8 | Parallel uploads/deletes. | | retries | number | 3 | Retries per failed upload/delete/list/purge (exponential backoff). 0 disables. | | ignore | string[] | [] | Glob patterns to skip. Supports **, *, and literals. | | dryRun | boolean | false | Compute and print the diff without writing anything. |

How it works

1. Walks the output folder computing a streaming SHA256 per file.
2. Lists the Storage Zone recursively. The Bunny SDK returns SHA256 checksums in the listing, so no files are downloaded.
3. Diffs local vs remote by hash into toUpload, toDelete, unchanged.
4. Uploads changed files (with the correct Content-Type per extension, since Bunny Storage does not infer it), then deletes orphaned remote files.
5. Purges the Pull Zone via the public purge API.

If an upload fails, the run aborts before any delete or purge. If the purge fails, the run still succeeds with a warning — the files are uploaded and the cache expires by TTL.

Develop

pnpm install
pnpm test          # vitest
pnpm run typecheck
pnpm run build     # emits dist/

Tests cover env loading, file walking, diffing, the concurrency pool, the Bunny client, and the deploy orchestrator. The orchestrator uses a small dependency injection seam so tests bypass the SDK and the real filesystem; there are no E2E tests against live Bunny — verify those with ng deploy --dry-run.
