apig-swagger-ui
Command line tool for generating OpenAPI spec and SwaggerUI from AWS API Gateway
Typical usage:
$ npx apig-swagger-ui -r ap-southeast-2 -s
npx: installed 92 in 9.635s
Clearing destination folder: api-doc
Generating OpenAPI spec for: https://api.dev1.insights.example.com/analytics
Generating OpenAPI spec for: https://boi.example.com/statement
Generating OpenAPI spec for: https://catalog.tst1.example.com/
Generating OpenAPI spec for: https://cis.example.com/
Generating OpenAPI spec for: https://leads.example.com/v2
Generating OpenAPI spec for: https://leads.example.com/inbound
Generating OpenAPI spec for: https://rulehub.example.com/citizenship
Generating OpenAPI spec for: https://toggle-feature-flag-datadog.example.com/
Generating OpenAPI spec for: https://v1pde.example.com/key
Local server started. Ctrl-C to stop. Access URL: http://localhost:8001/
Command line option -r ap-southeast-2
specifies AWS region,
-s
tells the command line to start up a local http server and then open the browser pointing to that local server for viewing generated website.
Multiple regions can be specified, in case you want to survey APIs in more than one region.
If you don't want to include all custom domains and APIs,
you can use --include
and --exclude
options to specify which domain/path to include and which to exclude.
Both of them can have multiple appearances.
For example, --include 'leads*/*'
will make sure that only https://leads.example.com/v2
and https://leads.example.com/inbound
would be included.
Make sure you have the pattern enclosed with '
.
--include
is applied before --exclude
, so that --include 'leads*/*' --exclude '*/v2'
will give you only https://leads.example.com/inbound
.
To match an endpoint URL without a base path, use patterns like *.example.*/
which matches https://cis.example.com/
.
Please note that *.example.*/*
does not match https://cis.example.com/
.
This applies to both inclusion and exclusion.
Necessary transformation/hacking is in place for making sure API spec looks good in Swagger UI. Feel free to let me know if you have any suggestions or needs, I would consider to add as new features.
Files generated are ready to be hosted as static website content in this structure:
api/
- folder containing all OpenAPI 3 spec files<domain>/
- folder containing OpenAPI 3 spec files under the same API Gateway custom domain name<basePath>.apig.json
- original OpenAPI 3 spec file exported from API Gateway<basePath>.json
- OpenAPI 3 spec file for SwaggerUI to consume. Necessary transformation/hacking has been applied for making sure the API spec looks good in Swagger UI.
swagger-ui/
- standard swagger-ui html/js/css/pngindex.html
- the home page / entry point
Quick start
In Node.js environment
You can have it installed globally like this:
$ npm install -g apig-swagger-ui
$ apig-swagger-ui ...
...
Or, you can just invoke the latest version with npx
:
$ npx apig-swagger-ui ...
...
By passing -h
or --help
to the command line, you can see all supported arguments and options.
It can also be used in your own code, like this:
import ApigSwaggerUi from 'apig-swagger-ui';
class Generator extends ApigSwaggerUi {
argv: string[] = ['api-doc/prod', '-r', 'ap-southeast-2'];
}
await Generator.run();
Install pre-built binary
apig-swagger-ui can be installed through Homebrew (brew install handy-common-utils/tap/apig-swagger-ui for Linux or MacOS), snap (snap install apig-swagger-ui for Linux except WSL), or manual download (https://github.com/james-hu/apig-swagger-ui/releases for Windows, Linux, and MacOS ).

DESCRIPTION
Command line tool for generating OpenAPI spec and Swagger UI from AWS API
Gateway
This command line tool can generate a static website that you can host for
serving Swagger UI of your API Gateway APIs.
It generates website files locally and can optionally launch a local server
for you to preview.
Before running this tool, you need to log into your AWS account (through
command line like aws, saml2aws, okta-aws, etc.) first.
Please note that only APIs that have been mapped to custom domains will be
included in the website generated.
EXAMPLES
$ apig-swagger-ui -r ap-southeast-2 -s
$ apig-swagger-ui -r ap-southeast-2 -r us-east-1 -s -i '*uat1*/*' -x 'datahub.uat1.*/*'
$ apig-swagger-ui -r ap-southeast-2 -s -i '*/key*' -i 'boi.stg.*/*' path/to/api-doc/directory
