Setting up a dev environment

Swagger UI includes a development server that provides hot module reloading and unminified stack traces, for easier development.

Prerequisites

• git, any version
• NPM 6.x

Generally, we recommend the following guidelines from Node.js Releases to only use Active LTS or Maintenance LTS releases.

Current Node.js Active LTS:

• Node.js 12.x
• NPM 6.x

Current Node.js Maintenance LTS:

• Node.js 10.x
• NPM 6.x

Unsupported Node.js LTS that should still work:

• Node.js 8.13.0 or greater
• NPM 6.x

Steps

1. git clone https://github.com/swagger-api/swagger-ui.git
2. cd swagger-ui
3. npm run dev
4. Wait a bit
5. Open http://localhost:3200/

Using your own local api definition with local dev build

You can specify a local file in dev-helpers/index.html by changing the url parameter. This local file MUST be located in the dev-helpers directory or a subdirectory. As a convenience and best practice, we recommend that you create a subdirectory, dev-helpers/examples, which is already specified in .gitignore.

replace

url: "https://petstore.swagger.io/v2/swagger.json",

with

url: "./examples/your-local-api-definition.yaml",

Files in dev-helpers should NOT be committed to git. The exception is if you are fixing something in index.html or oauth2-redirect.html, or introducing a new support file.

Bonus points

• Swagger UI includes an ESLint rule definition. If you use a graphical editor, consider installing an ESLint plugin, which will point out syntax and style errors for you as you code.
  • The linter runs as part of the PR test sequence, so don’t think you can get away with not paying attention to it!
