🕰️ Looking for the older version of Swagger Editor? Refer to the 2.x branch.

Swagger Editor lets you edit OpenAPI API definitions 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).

As a brand new version, written from the ground up, there are some known issues and unimplemented features. Check out the Known Issues section for more details.

This repository publishes to two different NPM modules:

• 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.

For the older version of swagger-editor, refer to the 2.x branch.

Running locally

Prerequisites

• NPM >=7.x

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

Current Node.js:

• Node.js 16.x
• NPM >=7.10.x

Current Node.js Active LTS:

• Node.js 14.x
• NPM >=7.x.x

If you have Node.js and npm installed, you can run npm start to spin up a static server.

Otherwise, you can open index.html directly from your filesystem in your browser.

If you'd like to make code changes to Swagger Editor, you can start up a Webpack hot-reloading dev server via npm run dev.

Browser support

Swagger Editor works in the latest versions of Chrome, Safari, Firefox, and Edge.

Known Issues

To help with the migration, here are the currently known issues with 3.X. This list will update regularly, and will not include features that were not implemented in previous versions.

• Everything listed in Swagger UI's Known Issues.
• The integration with the codegen is still missing.

Docker

Running the image from DockerHub

There is a docker image published in DockerHub.

To use this, run the following:

docker pull swaggerapi/swagger-editor
docker run -d -p 80:8080 swaggerapi/swagger-editor

This will run Swagger Editor (in detached mode) on port 80 on your machine, so you can open it by navigating to http://localhost in your browser.

• You can provide a URL pointing to an API definition (may not be available if some security policies such as CSP or CORS are enforced):

docker run -d -p 80:8080 -e URL="https://petstore3.swagger.io/api/v3/openapi.json" swaggerapi/swagger-editor

• You can provide your own json or yaml definition file from your local host:

docker run -d -p 80:8080 -v $(pwd):/tmp -e SWAGGER_FILE=/tmp/swagger.json swaggerapi/swagger-editor

Note: When both URL and SWAGGER_FILE environment variables are set, URL has priority and SWAGGER_FILE is ignored.

• You can specify a different base url via BASE_URL variable for accessing the application - for example if you want the application to be available at http://localhost/swagger-editor/:

docker run -d -p 80:8080 -e BASE_URL=/swagger-editor swaggerapi/swagger-editor

• You can specify a different port via PORT variable for accessing the application, default is 8080.

docker run -d -p 80:80 -e PORT=80 swaggerapi/swagger-editor

You can also customize the different endpoints used by the Swagger Editor with the following environment variables. For instance, this can be useful if you have your own Swagger generator server:

Environment variable	Default value
URL_SWAGGER2_GENERATOR	https://generator.swagger.io/api/swagger.json
URL_OAS3_GENERATOR	https://generator3.swagger.io/openapi.json
URL_SWAGGER2_CONVERTER	https://converter.swagger.io/api/convert

If you want to run the Swagger Editor locally without the Codegen features (Generate Server and Generate Client) you can set the above environment variables to null (URL_SWAGGER2_CONVERTER=null).

Building and running an image locally

To build and run a docker image with the code checked out on your machine, run the following from the root directory of the project:

# Install npm packages (if needed)
npm install

# Build the app
npm run build

# Build an image
docker build -t swagger-editor .

# Run the container
docker run -d -p 80:8080 swagger-editor

You can then view the app by navigating to http://localhost in your browser.
