Local emulators. Real API contracts. Part of Mockingbird.
Stateful local emulator of Amazon Resource Groups Tagging API. ESM; Node 22+ or Bun 1.2+.
Usage
import {
GetResourcesCommand,
ResourceGroupsTaggingAPIClient,
TagResourcesCommand,
} from "@aws-sdk/client-resource-groups-tagging-api"
import { createServer } from "@crvouga/mockingbird-service-resource-groups-tagging-api/server"
// Test setup: the tagging client your application already uses, pointed at the emulator.
const server = await createServer()
const tagging = new ResourceGroupsTaggingAPIClient({
endpoint: server.url,
region: "us-east-1",
credentials: { accessKeyId: "fixture", secretAccessKey: "fixture" },
})
// Application code, unchanged.
await tagging.send(
new TagResourcesCommand({ ResourceARNList: ["arn:aws:s3:::orders"], Tags: { team: "checkout" } }),
)
const { ResourceTagMappingList } = await tagging.send(
new GetResourcesCommand({ TagFilters: [{ Key: "team", Values: ["checkout"] }] }),
)
// ResourceTagMappingList[0].ResourceARN === "arn:aws:s3:::orders"
await server.close()State lives in SQLite collections and participates in the shared runtime's namespace isolation, reset, timeline, clock, journal, metrics and fault controls. No AWS account is needed.
Implemented AWS operations: TagResources, UntagResources, GetResources, GetTagKeys, GetTagValues.
Operations outside this list fail explicitly. This package emulates API state, not AWS infrastructure, production quotas, billing, IAM enforcement, or provider consoles. Service-specific omissions and oracle evidence are recorded in the AWS coverage ledger.
Run bun run parity with LocalStack on http://127.0.0.1:4566; an unavailable oracle fails the run.
No LocalStack run is recorded for this integration. The parity command is a bounded read-only SDK envelope probe, not proof of full vendor equivalence.
