Generating string unions instead of enums

[CodeSmith32]

How do I change the enum types generated from native enums to basic string unions?

The generated code looks like,

export enum SomeEnum {
  Value1 = "value1",
  Value2 = "value2"
}

I instead need,

export type SomeEnum = "value1" | "value2";

It's breaking because we rely on pre-existing string-union types. The types are ultimately equivalent once compiled, but the typescript is complaining because "value1" | "value2" is somehow a different type from enum SomeEnum { ... }.

I imagine this will also be a problem for anyone trying to run the generated code directly from Node using --experimental-strip-types since native enums are not erasable.

Ahh! Found it! There's a generate-union-enums option that does this exactly :-)

swagger-typescript-api/index.ts

Lines 179 to 183 in a8c7e98

	"generate-union-enums": {
	type: "boolean",
	description: 'generate all "enum" types as union types (T1 | T2 | TN)',
	default: codeGenBaseConfig.generateUnionEnums,
	},

I'm using the programming api; so having added it to my options config, it worked fine:

generateApi({
  input: path.resolve(process.cwd(), "..."),
  output: path.resolve(process.cwd(), "..."),
  name: "api.ts",
  templates: path.resolve(process.cwd(), "..."),
  generateUnionEnums: true,  // <----------------------
});
