Ingestion pipeline architecture overview and convention reference. Use when you need a quick orientation to the pipeline framework or want to know which doctor agent to use for a specific concern.
Prevent Ethereum hashing bugs in JavaScript and TypeScript. Node's sha3-256 is NIST SHA3, not Ethereum Keccak-256, and silently breaks selectors, signatures, storage slots, and address derivation.
Prevent Ethereum hashing bugs in JavaScript and TypeScript. Node's sha3-256 is NIST SHA3, not Ethereum Keccak-256, and silently breaks selectors, signatures, storage slots, and address derivation. Use when hashing for Ethereum in JavaScript or TypeScript, or when a selector, signature, storage slot, or derived address is wrong.
Installing, configuring, and running @sasjs/server — the open-source NodeJS wrapper around the SAS binary that provides a REST API, filesystem (SASjs Drive), Stored Program execution, and web app streaming. Covers desktop vs server modes, runtime configuration (SAS/JS/Python/R), environment variables, auth (tokens, LDAP), and mock server types. Use when deploying, troubleshooting, or developing against sasjs/server.
Build production-ready RESTful APIs with Express.js including routing, middleware, validation, and error handling for scalable backend services
Validates NestJS request payloads with class-validator and class-transformer using a global ValidationPipe. Use when adding/refactoring DTOs, hardening boundary input, or removing manual validation from controllers.
Designs NestJS application services as use-case classes that orchestrate domain logic and ports without leaking the framework. Use when creating new use cases, refactoring services that mix HTTP/DB/domain, or moving from anemic services to OOP.
Adds structured JSON logging, correlation/trace IDs, metrics, and health endpoints. Use when wiring observability for a new service, debugging cross-service requests, or removing console.log.
Designs NestJS feature modules with clean dependency boundaries, provider scopes, and dynamic modules. Use when adding a new feature module, splitting a monolithic AppModule, or fixing tangled imports between modules.
Tests NestJS applications at unit, integration, and e2e levels using Test.createTestingModule and Supertest with hand-rolled fakes. Use when writing tests for use cases, controllers, or full HTTP flows.
