Zod ​
WARNING
Zod plugin is currently in beta. The interface might change before it becomes stable. We encourage you to leave feedback on GitHub.
About ​
Zod is a TypeScript-first schema validation library with static type inference.
Features ​
- seamless integration with
@hey-api/openapi-tsecosystem - Zod schemas for requests, responses, and reusable definitions
Installation ​
In your configuration, add zod to your plugins and you'll be ready to generate Zod artifacts. 🎉
export default {
input: 'https://get.heyapi.dev/hey-api/backend',
output: 'src/client',
plugins: [
// ...other plugins
'zod',
],
};SDKs ​
To add data validators to your SDKs, set sdk.validator to true.
export default {
input: 'https://get.heyapi.dev/hey-api/backend',
output: 'src/client',
plugins: [
// ...other plugins
'zod',
{
name: '@hey-api/sdk',
validator: true,
},
],
};Learn more about data validators in your SDKs on the SDKs page.
Output ​
The Zod plugin will generate the following artifacts, depending on the input specification.
Requests ​
A single request schema is generated for each endpoint. It may contain a request body, parameters, and headers.
const zData = z.object({
body: z
.object({
foo: z.string().optional(),
bar: z.union([z.number(), z.null()]).optional(),
})
.optional(),
path: z.object({
baz: z.string(),
}),
query: z.never().optional(),
});TIP
If you need to access individual fields, you can do so using the .shape API. For example, we can get the request body schema with zData.shape.body.
You can customize the naming and casing pattern for requests using the requests.name and requests.case options.
Responses ​
A single Zod schema is generated for all endpoint's responses. If the endpoint describes multiple responses, the generated schema is a union of all possible response shapes.
const zResponse = z.union([
z.object({
foo: z.string().optional(),
}),
z.object({
bar: z.number().optional(),
}),
]);You can customize the naming and casing pattern for responses using the responses.name and responses.case options.
Definitions ​
A Zod schema is generated for every reusable definition from your input.
const zFoo = z.number().int();
const zBar = z.object({
bar: z.array(z.number().int()).optional(),
});You can customize the naming and casing pattern for definitions using the definitions.name and definitions.case options.
Metadata ​
It's often useful to associate a schema with some additional metadata for documentation, code generation, AI structured outputs, form validation, and other purposes. If this is your use case, you can set metadata to true to generate additional metadata about schemas.
export default {
input: 'https://get.heyapi.dev/hey-api/backend',
output: 'src/client',
plugins: [
// ...other plugins
{
metadata: true,
name: 'zod',
},
],
};Examples ​
