The loopback:swagger converter is nice, and this tool makes it a bit nicer:

• batch conversion (without interaction needed)
• copy relations,acl etc defined in swagger

Basically it allows you to do a swagger/loopback syntax-mashup in 1 jsonfile. This allows you to model your api's using one model file. (instead of slapping your head around files)

Usage

npm install -g loopback-swagger-cli

then extend your swagger file with strongloop syntax like so:

{
  ...
  "pet": {
    "type": "object",
    "required": [
      "id",
      "name"
    ],
    "dataSource": "db",          <--
    "public":true,               <--
    "relations": {               <--
      "owner": {                 <-- see strongloop 
        "type": "belongsTo",     <-- model jsondocs for
        "model": "owner",        <-- fields / syntax
        "foreignKey": ""         <--
      }                          <--
    },
  ...

and then

$ slc loopback:swagger swagger.json # only needed once (see note)
$ loopback-swagger-cli swagger.json server/models server/model-config.json
writing /server/models/owner.json
writing /server/models/pet.json 
writing /server/model-config.json

NOTE: this cli-tool will leave the .js files alone, however use the loopback:swagger cmd to generate them otherwise loopback will complain.

here's an example of a loopback api served from one coffeescript-jsonfile:
