Summary

Error handling

This release includes a small breaking change:

Prior to this release, if an error occurred in the Handler, it would throw an Error object. In this release, the error response is assigned to c.res without throwing Error.

app.use('*', async (c, next) => {
  await next()
  // c.res is error reponse
})

app.get('/error', () => {
  throw new Error('Test error')
})

Then you can access the original Error object with c.error.

app.use('*', async (c, next) => {
  await next()
  const originalMessage = c.error.message
  //...
})

JSON array path validation

This is a pretty new feature. Support for array paths in JSON Path for use with Validator Middleware.

If there is a JSON request body as follows:

{
    "posts": [
        {
            "title": "Good Morning",
            "tags": ["Bar", true]
        },
        {
            "title": "Good Night",
            "tags": ["Bar", false]
        }
    ]
}

We can validate with the following rules:

app.post(
  '/posts',
  validator((v) => ({
    title: v.json('posts[*].title').asArray().isRequired(),
    secondTag: v.json('posts[*].tags[1]').asArray().asBoolean(),
  })),
  (c) => {
    return c.text('Valid')
  }
)
