Swagger/OpenAPI CLI
============================
[](https://www.npmjs.com/package/@apidevtools/swagger-cli)
[](LICENSE)
[](https://plant.treeware.earth/APIDevTools/swagger-cli)
> ⚠️ Swagger CLI has been deprecated, due to the maintenance burnden of trying to keep up with expectations of a huge userbase with little to no pull requests or support. [Redocly CLI](https://redocly.com/redocly-cli/) covers all of the same functionality, and has more advanced linting with custom rules, and we highly recommend using that instead. They have conveniently provided a [migration guide](https://redocly.com/docs/cli/guides/migrate-from-swagger-cli/) for existing Swagger CLI users. Read the review of [Redocly CLI from APIs You Won't Hate](https://apisyouwonthate.com/blog/redocly-cli/).
Features
--------------------------
- Validate Swagger/OpenAPI files in **JSON or YAML** format
- Supports multi-file API definitions via `$ref` pointers
- Bundle multiple Swagger/OpenAPI files into one combined file
Related Projects
--------------------------
- [Swagger Parser](https://github.com/APIDevTools/swagger-parser)
- [Swagger Express Middleware](https://github.com/APIDevTools/swagger-express-middleware)
Installation
--------------------------
Install using [npm](https://docs.npmjs.com/about-npm/):
```bash
npm install -g @apidevtools/swagger-cli
```
Usage
--------------------------
```
swagger-cli [options]
Commands:
validate Validates an API definition in Swagger 2.0 or OpenAPI 3.0 format
bundle Bundles a multi-file API definition into a single file
Options:
-h, --help Show help for any command
-v, --version Output the CLI version number
-d, --debug [filter] Show debug output, optionally filtered (e.g. "*", "swagger:*", etc.)
```
### Validate an API
The `swagger-cli validate` command will validate your Swagger/OpenAPI definition against the [Swagger 2.0 schema](https://github.com/OAI/OpenAPI-Specification/blob/master/schemas/v2.0/schema.json) or [OpenAPI 3.0 Schema](https://github.com/OAI/OpenAPI-Specification/blob/master/schemas/v3.0/schema.json). It also performs additional validations against the [specification](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md), which will catch some things that aren't covered by the schema, such as duplicate parameters, invalid MIME types, etc.
The command will exit with a non-zero code if the API is invalid.
```
swagger-cli validate [options]
Options:
--no-schema Do NOT validate against the Swagger/OpenAPI JSON schema
--no-spec Do NOT validate against the Swagger/OpenAPI specification
```
#### Git pre-commit hook
There is a useful Python tool called [pre-commit](https://pre-commit.com/) that can be used to execute a wide suite of pre-commit checks. The `swagger-cli validate` command can be integrated as part of a git pre-commit hook by adding the following configuration to the `repos` entry of an existing `.pre-commit-config.yaml` file.
```
- repo: https://github.com/APIDevTools/swagger-cli
rev: v2.2.1
hooks:
- id: swagger-validation
args: ["validate", ""]
```
The intention is to point to single root swagger that references multiple swagger definitions. The above hook will execute the `swagger-cli validation` against the root swagger anytime that a file matching the pattern `.*swagger.*\.(json|yaml|yml)` is modified. Any failures in this validation will prevent the git commit from being processed.
### Combine Multiple Files
The Swagger and OpenAPI specs allows you to split your API definition across multiple files using [`$ref` pointers](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#reference-object) to reference each file. You can use the `swagger-cli bundle` command to combine all of those referenced files into a single file, which is useful for distribution or interoperation with other tools.
By default, the `swagger-cli bundle` command tries to keep the output file size as small as possible, by only embedding each referenced file _once_. If the same file is referenced multiple times, then any subsequent references are simply modified to point to the _single_ inlined copy of the file. If you want to produce a bundled file without _any_ `$ref` pointers, then add the `--dereference` option. This will result in a larger file size, since multiple references to the same file will result in that file being embedded multiple times.
If you don't specify the `--outfile` option, then the bundled API will be written to stdout, which means you can pipe it to other commands.
The result of this method by default is written as JSON. It can be changed to YAML with the `--type` option, by passing the `yaml` value.
```
swagger-cli bundle [options]
Options:
-o, --outfile The output file
-r, --dereference Fully dereference all $ref pointers
-f, --format Formats the output using the given number of spaces
(the default is 2 spaces)
-t, --type Defines the output file type. The valid values are: json, yaml
(the default is JSON)
-w, --wrap Set the line length for YAML strings
(the default is no wrapping)
```
