Generate both static and runtime types from an intermediate language.
The intermediate language can in turn be generated from other schemas: JSON Schema, Swagger, metarpheus, etc..
io-ts-codegen version | target io-ts version |
|---|---|
| 0.4.0+ | 1.0.0+ || 2.0.0+ |
| 0.3.0+ | 1.0.0+ || 2.0.0+ |
Nodes of the intermediate language can be built from the provided builders.
import * as gen from 'io-ts-codegen' // list of type declarations const declarations = [ gen.typeDeclaration('Persons', gen.arrayCombinator(gen.identifier('Person'))), gen.typeDeclaration( 'Person', gen.typeCombinator([gen.property('name', gen.stringType), gen.property('age', gen.numberType)]) ) ] // apply topological sort in order to get the right order const sorted = gen.sort(declarations) console.log(sorted.map(d => gen.printRuntime(d)).join('\n')) console.log(sorted.map(d => gen.printStatic(d)).join('\n'))Output (as string)
const Person = t.type({ name: t.string, age: t.number }) const Persons = t.array(Person) interface Person { name: string age: number } type Persons = Array<t.TypeOf<typeof Person>>
