Merge multiple swagger files into a swagger file, support JSON/YAML.

Features

• Merge multiple swagger files into a swagger file.
• $ref - A tag, include a single-level of swagger file.
• $ref#* - A tag, include a multi-level of swagger file.
• Support JSON/YAML swagger files(.json/.yaml/.yml).
• CLI - Command line interface.

Usage

$ref

Includes a single-level of swagger file.

• Official standards
• Recommended, universal

For example:

$ref: "./host.yaml"
parameters:
  - $ref: "./name.yaml"
  - $ref: "./year.yaml"
  - $ref: "./age.yaml#/alex/son"
remote:
  $ref: "https://raw.githubusercontent.com/WindomZ/swagger-merger/remote.yaml#/name"
responses:
  $ref: "./responses.yaml#/post"

$ref#*

Includes a multi-level of swagger file.

• Non-standard, suggest you use it for yourself
• Instead of $ref, can be used side by side and not an array

For example:

paths:
  $ref#pets: "./paths/pets.yaml"
  $ref#pets-id: "./paths/pets-id.yaml"
definitions:
  $ref#pets: "https://raw.githubusercontent.com/WindomZ/swagger-merger/pets.yaml"
  $ref#error: "https://raw.githubusercontent.com/WindomZ/swagger-merger/error.yaml"

CLI

How to use?

$ swagger-merger -h

  Usage: swagger-merger [-h] [-v] [-c] [-o file] <-i file | file>

  Merge multiple swagger files into a swagger file, just support JSON/YAML.

  Options:

    -h, --help           output usage information
    -V, --version        output the version number
    -i, --input <file>   input a main/entry JSON/YAML swagger file
    -o, --output <file>  output a merged JSON/YAML swagger file, default is `swagger.*`
    -c, --compact        compact JSON/YAML format string
    --debug              debug mode, such as print error tracks

Easy to use.

swagger-merger -i in.yaml                # Merge in.yaml into swagger.yaml
swagger-merger -i in.yaml -o out.yaml    # Merge in.yaml into out.yaml
swagger-merger -i in.yaml -o out.yaml -c # Merge in.yaml into out.yaml and compress it
swagger-merger -i in.yaml -o out.json    # Merge in.yaml into out.json

swagger-merger -i in.json                # Merge in.json into swagger.json
swagger-merger -i in.json -o out.json    # Merge in.json into out.json
swagger-merger -i in.json -o out.json -c # Merge in.json into out.json and compress it
swagger-merger -i in.json -o out.yaml    # Merge in.json into out.yaml
