@burdenoff/sdk-libs

Modular SDK library shared across all Burdenoff product SDKs (Node/TypeScript).

Each module under src/modules/<name>/ exports an SdkModule with attach(ctx) -> API. Product SDKs (@vibecontrols/sdk-node, @botlit/sdk-node, etc.) become thin shells that pick which modules to mount. Sister to @burdenoff/cli-sdk.

Architecture

• Core (src/core/): SdkContext prop bag, SdkModule contract, BaseGraphQLClient (dual workspace+global gateway), AuthStore with pluggable TokenStore (InMemory, File, Env), error hierarchy with token redaction, ModuleRegistry for cross-module access.
• Modules (src/modules/<name>/): index.ts (default-exports SdkModule), operations.ts (hand-written gql strings), api.ts (the class returned by attach), types.ts (re-exports from __generated__/), __generated__/types.ts (codegen output, gitignored).
• Hard rules: Modules NEVER import each other directly — use ctx.modules.get<API>('id'). Modules NEVER call process.exit or write secrets to logs.

Build

• tsup dual ESM+CJS, multi-entry, dts: true. Entries: src/index.ts, src/core/index.ts, src/modules/*/index.ts.
• external: graphql, graphql-request, graphql-ws (peer deps).
• Subpath imports: @burdenoff/sdk-libs/core, @burdenoff/sdk-libs/modules/<name>.

Commands

bun install
bun run dev               # tsup watch
bun run build             # tsup once
bun run sanity            # format:check + lint + typecheck + build + test
bun run test              # vitest run
bun run codegen           # GraphQL types from pinned Hive supergraph
bun run parity:check      # cross-language manifest diff vs sdk-libs-python
bun run publish:verdaccio # alpha tag to internal Verdaccio

Adding a module

1. mkdir src/modules/<name> with index.ts, operations.ts, api.ts, types.ts.
2. Default-export an SdkModule<API> from index.ts.
3. Add the module to schema/modules.yaml (operations + dependsOn).
4. Mirror in ~/products/sdk-libs-python/ in the same PR pair.
5. tsup picks it up automatically (src/modules/*/index.ts glob).

Testing

• Unit (tests/unit/): pure logic — arg parsers, response transformers, gql doc builders. No HTTP. Vitest, <5s.
• Integration (tests/integration/): MSW intercepts GraphQL requests. Mock factories derived from __generated__/types. Schema rename breaks mock = test fail.
• E2E (tests/e2e/): real svc + state, run nightly. Mirrors ~/products/vibecontrols/vibecontrols-doctor/scripts/test-*-crud.sh.
• Parity (tests/parity/<scenario>.yaml): same scenario file run by node + python. CI fails if shapes diverge.
