💎 options

--templates

This option needed for cases when you don't want to use the default swagger-typescript-api output structure

Templates:

• api.eta - Api class module (locations: /templates/default, /templates/modular)
• data-contracts.eta - all types (data contracts) from swagger schema (locations: /templates/base)
• http-client.eta - HttpClient class module (locations: /templates/base)
• procedure-call.eta - route in Api class (locations: /templates/default, /templates/modular)
• route-docs.eta - documentation for route in Api class (locations: /templates/base)
• route-name.eta - route name for route in Api class (locations: /templates/base)
• route-type.eta - (--route-types option) (locations: /templates/base)
• route-types.eta - (--route-types option) (locations: /templates/base)

How to use it:

• copy swagger-typescript-api templates into your place in project
  • from /templates/default for single api file
  • from /templates/modular for multiple api files (with --modular option)
  • from /templates/base for base templates (templates using both in default and modular)
• add --templates PATH_TO_YOUR_TEMPLATES option
• modify ETA templates as you like

NOTE:
Eta has special directive to render template in your Eta templates - includeFile(pathToTemplate, payload)
If you want to use some default templates from this tool you can use path prefixes: @base, @default, @modular.
@base - path to base templates
@default - path to single api file templates
@modular - path to multiple api files templates
Examples:
- includeFile("@base/data-contracts.eta", configuration)
- includeFile("@default/api.eta", configuration)
- includeFile("@default/procedure-call.eta", configuration)
- includeFile("@modular/api.eta", configuration)
- includeFile("@modular/procedure-call.eta", configuration)
- includeFile("@base/route-docs.eta", configuration)
- includeFile("@base/route-name.eta", configuration)
- includeFile("@base/route-type.eta", configuration)
- includeFile("@base/route-types.eta", configuration)

--module-name-index

This option should be used in cases when you have api with one global prefix like /api
Example:
GET:/api/fruits/getFruits
POST:/api/fruits/addFruits
GET:/api/vegetables/addVegetable
with --module-name-index 0 Api class will have one property api
When we change it to --module-name-index 1 then Api class have two properties fruits and vegetables

--module-name-first-tag

This option will group your API operations based on their first tag - mirroring how the Swagger UI groups displayed operations
