api-codegen-ts
A general typescript code generation library. Currently it can take swagger 2.0 and openapi 3.0.0+ json specs and turn them into typescript controllers that validate api responses.
Installation
npm i -D @nll/api-codegen-ts
Configuration
Add an apiCodegen section to package.json.
{
"apiCodegen": {
"src": "./path/to/your/swagger-spec.json",
"dst": "./path/to/your/codegen/destination"
}
}Usage
After configuring api-codegen-ts you can generate code like so:
npx @nll/api-codegen-ts
And it will output its progress and output code.
Advanced usage
This codegen library abstracts parsers and printers. A parser is responsible for receiving an input string (a specification) and generating any intermediate representation. Currently, there are primitive swagger 2.0 and openapi 3.0.0 parsers. A printer takes an intermediate representation (it must match whatever the parser outputs) and returns the file strings to write to disk. The core functionality of api-codegen-ts is managing this workflow, it handles the reading of the source files and the printing of the generated files.
Support
This is my first attempt at a codegen library. If you find bugs or some set of features that aren't supported please create a github issue. Thanks!
