    OpenZeppelin Contracts

    OpenZeppelin Contracts

    OpenZeppelin Contracts is a library for secure smart contracts

    A library for secure smart contract development. Build on a solid foundation of community-vetted code.

    ink-kit

    Onchain-focused SDK with ready-to-use templates and themes

    ink-kit is a developer toolkit for building applications on the INK blockchain ecosystem, bundling the pieces you typically need to go from a blank repo to a working dapp. It provides contract templates, deployment scripts, and client SDKs so you can iterate on on-chain logic and a frontend without stitching together disparate tools. The kit standardizes project layout and environment configuration, making local development, testing, and staging deploys predictable. Utilities for wallet connection, signing, and basic indexing help you focus on business logic rather than bootstrapping. ...

    Node.js Testing Best Practices

    Node.js Testing Best Practices

    Beyond the basics of Node.js testing

    This repository narrows the testing lens to Node.js backends, focusing on the challenges of servers, microservices, and cloud-native deployments. It covers API testing, contract testing, and persistence-layer strategies that avoid coupling tests to fragile implementation details. The material explains how to structure tests around process boundaries—HTTP, queues, cron jobs—while keeping fast feedback cycles through selective integration tests and reliable test doubles. It dives into topics like test containers, ephemeral databases, and idempotent fixtures to ensure deterministic runs in CI. ...

    RealWorld

    RealWorld

    Exemplary fullstack Medium.com clone powered by React, Angular, Node

    ...The same spec is realized dozens of times (React, Vue, Svelte, Angular, Solid, Next, Remix, and many more), alongside multiple server implementations, so learners can compare idioms without guessing about feature gaps. A shared API contract and test suite keep implementations consistent and reveal framework-specific tradeoffs clearly. This makes the repo a powerful teaching tool for architecture, state management, testing, and deployment patterns at production scale. Teams also use it to evaluate new frameworks by building “yet another RealWorld” and measuring DX, bundle size, and maintainability.

    Cancelable Async Flows

    Cancelable Async Flows

    Cancelable Async Flows (CAF)

    ...This approach avoids brittle timeouts and “fire-and-forget” leaks by making cancellation a first-class concern. CAF is framework-agnostic and pairs well with fetch, timers, or custom async primitives, giving you a consistent contract for stopping in-flight operations. The result is safer UI interactions and services that don’t keep doing work the user no longer needs.

    SPL Compiler

    A low-level system programming language with high-level syntax

    ... * Be as efficient as C (at run-time) and as high-level as possible for the programmer. * Promote modularity and ease the development of large-scale component-based software. * Enable programming-by-contract and other high-level features (as long as they incur no extraordinary costs at run-time). * Provide a stricter and more platform-independent type system than C. * Allow direct use of existing C and platform (e.g. Win32 API) libraries. This phrase from the "SPL Language Reference" says it all: "One could say SPL is what C should have been, were it not for the limitations of the time when C was designed".

    PHP Design by Contract

    Base class for PHP 5.3+ which allows design by contract in PHP

    PHP Design by Contract provides a basic implementation of contract programming in PHP 5.3+. The base Contract class allows new or existing classes to define properties as protected Attributes and methods as Routines, which require argument type/class validation, aswell as PreCondition and PostCondition checks. Instances can also check for state consistency with an invariant check.
