The OpenAPI specification is widely used to define RESTful APIs. One of the critical components of an OpenAPI specification is the server section, which provides a list of URLs where the API can be accessed. However, working with the server section can be complicated, especially when the server URLs contain variables and other dynamic components. That's where openapi-url-resolver comes in.
Below is a server object example,
{
"servers": [
{
"url": "https://{username}.gigantic-server.com:{port}/{basePath}",
"description": "The production API server",
"variables": {
"username": {
"default": "demo",
"description": "this value is assigned by the service provider, in this example `gigantic-server.com`"
},
"port": {
"enum": [
"8443",
"443"
],
"default": "8443"
},
"basePath": {
"default": "v2"
}
}
}
]
}
