Installation

bun pm trust @freehour/supabase-core @freehour/supabase-langchain

If you generate migrations from schemas, make sure to include the supabase-core, supabase-langchain schema in your schema_paths in supabase/config.toml.

schema_paths = [
    "./schemas/supabase-core/*.sql",
    "./schemas/supabase-langchain/*.sql",
    /* your app schema paths */
]
