Migration from 2.x

v2 features may not work in v3. In order to upgrade an existing server to v3, you must apply the changes in v3.

#Packages

All actions were performed in the zely module, but the method has changed to the @zely-js/~ module sharing the responsibility for actions.

To use zely and cli together, install zely. If you only want to use zely API, install @zely-js/zely.

#File Structure

$routing is deprecated.

#Migration

  const res = ctx.response;
  // ...
}

snatcher has been deprecated. Use fetch instead.
