Is possible to change a Uni's Schema

#1

I want to update some properties of our existing schema to avoid creating a new universal application. Is this possible? If so, how is it done?

Hi @Josh ,

Yes - you can make a change to the uni’s schema with the Schema Evolution feature by using the following command in the Share CLI, referencing a .json file with your new schema (e.g. evolved-schema.json).

share uni evolve --uni your-uni-name \
--schema evolved-schema.json

One caution is a schema cannot evolve to changes that are destructive or breaking changes, which includes:

  • Existing types cannot be removed
  • Existing properties cannot be removed
  • Type changes to existing properties cannot be changed
  • Required flag for an existing property cannot be changed

An example is available here: Vendia - Schema Evolution
