⏰️ Looking for the next generation version of Swagger Editor?

SwaggerEditor is now released under two major release channels:

SwaggerEditor@4 - released from master branch and deployed at https://editor.swagger.io/
SwaggerEditor@5 - released from next branch and deployed at https://editor-next.swagger.io/

Only SwaggerEditor@5 supports OpenAPI 3.1.0. SwaggerEditor@4 will not receive OpenAPI 3.1.0 support and is considered legacy at this point. The plan is to continually migrate fully to SwaggerEditor@5 and deprecate the SwaggerEditor@4 in the future.

🕰️ Looking for the older version of Swagger Editor? Refer to the 2.x or 3.x branches.

Swagger Editor lets you edit OpenAPI API definitions (OpenAPI 2.0 and OpenAPI 3.0.3) in JSON or YAML format inside your browser and to preview documentations in real time. Valid OpenAPI definitions 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.

Anonymized analytics

Swagger Editor uses Scarf to collect anonymized installation analytics. These analytics help support the maintainers of this library and ONLY run during installation. To opt out, you can set the scarfSettings.enabled field to false in your project's package.json:

// package.json
{
  // ...
  "scarfSettings": {
    "enabled": false
  }
  // ...
}

Alternatively, you can set the environment variable SCARF_ANALYTICS to false as part of the environment that installs your npm packages, e.g., SCARF_ANALYTICS=false npm install.

Running locally

Prerequisites

git, any version
Node.js >=20.3.0 and npm >=9.6.7 are the minimum required versions that this repo runs on, but we always recommend using the latest version of Node.js.

 $ npm i --legacy-peer-deps

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 specify Google Tag Manager ID via GTM variable for tracking the usage of the swagger-editor.

docker run -d -p 80:8080 -e GTM=GTM-XXXXXX 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.

Documentation

Using older version of React

Important

By older versions we specifically refer to React >=17 <18.

By default swagger-editor@4 npm package comes with latest version of React@18. It's possible to use swagger-editor@4 npm package with older version of React.

Let's say my application integrates with swagger-editor@4 npm package and uses React@17.0.2.

npm

In order to inform swagger-editor@4 npm package that I require it to use my React version, I need to use npm overrides.

{
  "dependencies": {
    "react": "=17.0.2",
    "react-dom": "=17.0.2"
  },
  "overrides": {
    "swagger-editor": {
      "react": "$react",
      "react": "$react-dom",
      "react-redux": "^8"
    }
  }
}

Note

The React and ReactDOM override are defined as a reference to the dependency. Since react-redux@9 only supports React >= 18, we need to use react-redux@8.

yarn

In order to inform swagger-editor@4 npm package that I require it to use my specific React version, I need to use yarn resolutions.

{
  "dependencies": {
    "react": "17.0.2",
    "react-dom": "17.0.2"
  },
  "resolutions": {
    "swagger-editor/react": "17.0.2",
    "swagger-editor/react-dom": "17.0.2",
    "swagger-editor/react-redux": "^8"
  }
}

Note

The React and ReactDOM resolution cannot be defined as a reference to the dependency. Unfortunately yarn does not support aliasing like $react or $react-dom as npm does. You'll need to specify the exact versions.
