    gqlgen

    gqlgen

    Go generate based graphql server library

    gqlgen is a Go library for building GraphQL servers without any fuss. You get to Define your API using the GraphQL Schema Definition Language. You should never see map[string]interface{} here. We generate the boring bits, so you can focus on building your app quickly. Still not convinced enough to use gqlgen? Compare gqlgen with other Go graphql implementations. You need to tell gqlgen that it should only fetch friends if the user requested it. gqlgen will be able to automatically bind to strings or ints for models you have written yourself. gqlgen is a schema-first library, before writing code, you describe your API using the GraphQL Schema Definition Language. ...

    Path-to-RegExp

    Path-to-RegExp

    Turn a path string such as `/user/:name` into a regular expression

    The path argument is used to define parameters and populate keys. The RegExp returned by path-to-regexp is intended for ordered data (e.g. pathnames, hostnames). It can not handle arbitrarily ordered data (e.g. query strings, URL fragments, JSON, etc). When using paths that contain query strings, you need to escape the question mark (?) to ensure it does not flag the parameter as optional.

    hyper for Rust

    hyper for Rust

    An HTTP library for Rust

    ...If you are looking for a convenient HTTP client, then you may wish to consider reqwest. If you are looking for a convenient HTTP server, then you may wish to consider warp. Both are built on top of this library. A Service lets you define how to respond to incoming requests. While it is possible to implement the trait directly, there are a few patterns that are common when using Hyper. We’ve included some helpers for when these patterns fit our needs. An echo server will listen for incoming connections and send back the request body as the response body on POST requests.

    Meteroid

    Meteroid

    Open-source pricing and billing infrastructure

    Meteroid is an open-source, cloud-native pricing and billing infrastructure designed to support usage-based billing, subscription management, invoicing, and cost-tracking — particularly for SaaS or product-led businesses that need flexible billing models beyond flat subscriptions. It provides an API-driven billing engine: you feed Meteroid usage data from your application (e.g. API calls, storage usage, seats, feature usage), define custom pricing rules or plans, and Meteroid calculates charges, generates invoices, tracks usage, and supports cost limits or quotas. The system is written in Rust, emphasizing performance, reliability, and safety, making it suitable for production use in small startups up to large enterprises. Meteroid handles complexities like plan versioning, usage-based billing, re-invoicing, grandfathering of plans, experiments, and cost limiting — giving teams a robust billing backend without building one from scratch.

    AWS SAM CLI

    AWS SAM CLI

    CLI tool to build, test, debug, and deploy Serverless applications

    ...The AWS Serverless Application Model (SAM) is an open-source framework for building serverless applications. It provides shorthand syntax to express functions, APIs, databases, and event source mappings. With just a few lines per resource, you can define the application you want and model it using YAML. During deployment, SAM transforms and expands the SAM syntax into AWS CloudFormation syntax, enabling you to build serverless applications faster. To get started with building SAM-based applications, use the SAM CLI. SAM CLI provides a Lambda-like execution environment that lets you locally build, test, debug, and deploy AWS serverless applications.
