EdgeDB provides schema migration tools as server-side tools. This means that, from the point of view of the application, migrations are language- and platform-agnostic and don’t require additional libraries.
Using the migration tools is the recommended way to make schema changes.
First of all, the migration tools need a place to store the schema and
migration information. By default they will look in the
directory, but it’s also possible to specify any other location by
using the schema-dir option.
Inside this directory, you will find an
.esdl file with an SDL schema description. You may split your schema across multiple
.esdl files. The migration tools will read all of them and treat them as a
single SDL document.
