File format upgrade might trigger migration

[kneth]

What, How & Why?

Upgrading the Realm file format might trigger a migration, and when deleting the file as migration (typically done during development), users can experience data loss.

The file foo.realm has been generated by the following script and Realm JS v10.9.1:

const Realm = require("realm");
const schema = {
  name: "Object",
  properties: {
    value: "int"
  },
};

let realm = new Realm({ path: "foo.realm", schema: [schema] });
realm.write(() => {
  realm.create("Object", { value: 42 } );
});
realm.close();
