Reqbook

Preview, validate, run, and inspect Reqbook API specs from VS Code.

Requirements

Install the rqb binary first:

cargo install reqbook
# or
npm install -g reqbook

The extension auto-detects rqb from RQB_PATH, the workspace target/debug or target/release directories, Cargo's ~/.cargo/bin, Homebrew paths, and the VS Code process PATH. Set reqbook.rqbPath only when you need an explicit override.

Demo

Watch the official VS Code demo in the docs: https://docs.markapidown.net/guides/vscode-extension#demo

Commands

• Reqbook: Preview Endpoint
• Reqbook: Run Spec
• Reqbook: Validate Current File
• Reqbook: Show Agent Context

Auto-detect run buttons

When you open a runnable Reqbook file, the extension shows a CodeLens run button at the top of the editor and a Run button in the editor title bar.

• The collection root is the nearest parent directory with reqbook.md or mad.md; it does not need to be named api-docs.
• Endpoint specs with method: and path: frontmatter run with rqb exec.
• Flow and pipeline specs under <collection>/flows/ or <collection>/pipelines/ run with rqb flow.
• Collection docs such as <collection>/reqbook.md, <collection>/mad.md, README.md, and _shared/env.md do not show run buttons.

Completion

Markdown completion suggests variables from:

• <collection>/_shared/env.md
• .env.local
• path params in the current spec
• Capture: ... as <name> directives in related flows and pipelines

Completion is offered while editing {{variable}} templates and path params.

Settings

• reqbook.rqbPath: optional path to the rqb binary, default rqb
• reqbook.env: default environment for run/context, default dev
• reqbook.apiDocsRoot: optional collection root override
• reqbook.resultPanel: show command output in a result panel

Install from VSIX

For pre-release builds, install the packaged VSIX from the command line:

code --install-extension reqbook-vscode-0.2.6.vsix

Then open a workspace with a Reqbook collection and run Reqbook: Validate Current File against an endpoint markdown file.

Release package

npm ci
npm test
npm run check
npm run package -- --out /tmp/reqbook-vscode-0.2.6.vsix
