Do you know good openapi v3 spec library for go ?

[chenjpu]

kin-openapi ,is it okay?

[betabandido]

It does not look like go-openapi will support openapi 3 any time soon. See:

go-openapi/spec#21
go-openapi/spec3#1

kin-openapi appears mentioned in the first issue as a good candidate to provide openapi 3 support. So, it might be a good idea to look into it.

Not supporting openapi 3 makes impossible to document APIs that could otherwise be documented with swag (e.g., when using QueryMap method in Gin).

Hi guys,
any updates?

[OneCricketeer]

I've worked around this with some Make targets

The first runs swag init on the root project, creating the docs/swagger.json and docs/swagger.yaml

The second mounts that folder and generates a v3 folder with openapi-generator-cli

docs
├── .openapi-generator-ignore
├── docs.go
├── swagger.json
├── swagger.yaml
└── v3
    ├── README.md
    ├── openapi.json
    └── openapi.yaml

Run make ci-swaggen, and we've hooked into our CI pipeline on every commit to master

Runs with make ci-swaggen, and is hooked into our CI pipeline on every commit to master

Excuse me, I don't understand how to use it, would you like to help me ?

[OneCricketeer]

@lifegit Create a Makefile with that content, and run the command I mentioned

[lifegit]

@OneCricketeer
