Code generation for io-ts
npm install io-ts-codegenGenerate 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 compatibility| 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.
``ts
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)
`ts``
const Person = t.type({
name: t.string,
age: t.number
})
const Persons = t.array(Person)
interface Person {
name: string
age: number
}
type Persons = Array
