h3-typebox

JSON schema validation for h3, using typebox & ajv.

Install

# Using npm
npm install h3-typebox

# Using yarn
yarn install h3-typebox

# Using pnpm
pnpm install h3-typebox

Usage

import { createServer } from 'http'
import { createApp } from 'h3'
import { validateBody, validateQuery, Type } from 'h3-typebox'

const app = createApp()
app.use('/', async (event) => {
  // Validate body
  const body = await validateBody(event, Type.Object({
    optional: Type.Optional(Type.String()),
    required: Type.Boolean(),
  }))

  // Validate query
  const query = validateQuery(event, Type.Object({
    required: Type.String(),
  }))
})

createServer(app).listen(process.env.PORT || 3000)

See how to define your schema with Type on TypeBox documentation.

Options

You can define a options object on validateBody or validateQuery. Currently the following options are supported:

includeAjvFormats: Boolean

includeAjvFormats

Some formats like date, date-time or email are specified in the current JSONSchema draft, but not included in ajv by default, but provided by the ajv-formats package. If one of these formats is needed, you can specify includeAjvFormats: true in the options of validateBody or validateQuery like this:

// Body
validateBody(event, schema, { includeAjvFormats: true })

// Query
validateQuery(event, schema, { includeAjvFormats: true })

Currently, only the following extended formats are supported for performance and security reasons:

date-time
time
date
email
uri
uri-reference

These can be used by custom schemas with the Type.Unsafe method or with an inline schema:

const bodySchema = Type.Object({
  optional: Type.Optional(Type.String()),
  dateTime: Type.String({ format: 'date-time' })
})
validateBody(event, bodySchema, { includeAjvFormats: true })
