gangway

v0.2.6

Charts, diagrams, documents, decks and canvases on a real HTTPS URL on your own gangway server, in place of built-in artifacts; a quick place to put up new apps, with a database if they need one; and previews of every pull request in a GitHub repository.

Included Skills3

create-themeskills/create-theme/SKILL.md

Create or update a gangway artifact theme from a source -- a website, a stylesheet or design-tokens file, a Tailwind config, a brand guide, a logo, or a description -- so the user's documents, decks and canvases come out in their own brand. Maps the source onto gangway's colour tokens for light and dark, its fonts, a shape and layout style and a logo, saves it with the MCP theme tool, and shows it on a sample artifact. Use when the user asks for a custom theme, their brand's look, or to change an existing theme.

deploy-onceskills/deploy-once/SKILL.md

Deploy the app in the current directory or repository to a gangway URL once, as it is on disk, with no CI or workflow; redeploy to the same URL later. Use when the user asks to put this repo or app up on gangway, to share a running copy, or to try it on a real URL. For a preview of every pull request, use setup-pr-previews instead.

setup-pr-previewsskills/setup-pr-previews/SKILL.md

Set up gangway pull-request previews for the GitHub repository in the current directory, so every PR gets its own URL on the user's gangway server. Connects the repo to gangway with the MCP project tool, adds a Dockerfile if the repo has none, commits the generated GitHub Actions workflow on a branch and opens a PR that proves it works. Use when the user asks for PR previews, preview deployments or review apps on gangway for a repo.
