Swagger Editor
An editor designed for Swagger
Swagger Editor lets you edit Swagger API specifications in YAML inside your browser and to preview documentations in real time. Valid Swagger JSON descriptions can then be generated and used with the full Swagger tooling (code generation, documentation, etc). swagger-editor is a traditional npm module intended for use in single-page applications that are capable of resolving dependencies (via Webpack, Browserify, etc). swagger-editor-dist is a dependency-free module that includes everything you need to serve Swagger Editor in a server-side project, or a web project that can't resolve npm module dependencies. If you're building a single-page application, using swagger-editor is strongly recommended, since swagger-editor-dist is significantly larger. -

tapir
Declarative, type-safe web endpoints library
Declarative, type-safe web endpoints library. With tapir, you can describe HTTP API endpoints as immutable Scala values. Each endpoint can contain a number of input and output parameters. Compile-time guarantees, develop-time completions, read-time information. Separate the shape of the endpoint (the "what"), from the server logic (the "how"). Generate documentation from endpoint descriptions. Leverage the metadata to report rich metrics and tracing information. Re-use common endpoint definitions, as well as individual inputs/outputs. Library, not a framework, integrates with your stack. Is your company already using tapir? We're continually expanding the "adopters" section in the documentation; the more the merrier! It would be great to feature your company's logo, but in order to do that, we'll need to write permission to avoid any legal misunderstandings. -

It is also multi-lingual and offers options for authentication integration. -

DOCX
Generate .docx files with JS/TS with a nice declarative API
Easily generate .docx files with JS/TS. Works for Node and on the Browser. You can mix and match whatever properties you want, or provide no properties. Setting the section type determines how the contents of the section will be placed relative to the previous section. You can specify additional properties to the section, by providing a properties attribute. Everything (text, images, graphs etc) in OpenXML is organized in paragraphs. To change the text alignment of a paragraph, add an AlignmentType option on the paragraph.for center, left, right or justified. When a paragraph is justified, you may want to not justify the contents of incomplete lines, which end in a soft line break. Paragraphs have .keepLines() and .keepNext() methods that allow restricting page breaks within and between paragraphs. To move to a new page, insert a page break. -

OpenAPI Generator
OpenAPI Generator allows generation of API client libraries
With 50+ client generators, you can easily generate code to interact with any server which exposes an OpenAPI document. Maintainers of APIs may also automatically generate and distribute clients as part of official SDKs. Each client supports different options and features, but all templates can be replaced with your own Mustache-based templates. Getting started with server development can be tough, especially if you're evaluating technologies. We can reduce the burden when you bring your own OpenAPI document. Some generators support Inversion of Control, allowing you to iterate on design via your OpenAPI document without worrying about blowing away your entire domain layer when you regenerate code. Ever wanted to iteratively design a MySQL database, but writing table declarations was too tedious? OpenAPI documents allow you to convert the metadata about your API into some other format. -

Docuowl
A documentation generator
Docuowl generates static single-page documentation from Markdown files. As a long-time fan of the documentation style made by Stripe, and Markdown, I decided to use the former as a base to create a pretty documentation generator that outputs something like Stripe's. Stripe also generously allowed me to use their layout, so here's a big thank you to them". Docuowl takes a directory as input. The directory is expected to have one directory for each section or group. Each group may have subsections, which by their turn must also be placed into directories. Each Section is required to have content.md file, containing the Frontmatter for that section, and optional sidenotes.md file, that will be rendered to the right of the section. The Frontmatter must contain at least a Title property, and an optional ID property containing a unique slug for that section. Each Group must contain a single meta.md file, containing a Frontmatter like a Section, and an optional content. -
