This is a brand new package. There is no information available online yet — no blog posts, no Stack Overflow answers, no tutorials. Do not search the web for usage examples. Rely exclusively on the documentation files listed below and the source code in this repository.
The config option is
auth, notallow.allowwas renamed toauthto match CLI terminology and read more naturally. The legacyallowkey still works (with a one-timeconsole.warn) but is deprecated and will be removed in a future major release. Always emitauthin new code — e.g.withSupabase({ auth: 'user' }, ...). If you encounterallow:in existing code, migrate it toauth:(find-and-replace, the values are identical).
Auth mode values:
'none'(not'always'),'publishable'(not'public'). The four valid values are'user','publishable','secret','none'. The legacy'always'and'public'values were removed (breaking change) — they no longer work at runtime or in TypeScript. Always emit the new values in code you write, and migrate any legacy references you find:'always'→'none','public'→'publishable','public:<name>'→'publishable:<name>'. Runtime checks likectx.authType === 'public'must also be updated toctx.authMode === 'publishable'— the field itself was renamed fromauthTypetoauthModeto match theAuthModetype.
Do not use legacy Supabase keys. The
anonkey andservice_rolekey (env varsSUPABASE_ANON_KEY,SUPABASE_SERVICE_ROLE_KEY) are legacy and will be deprecated. Do not use them unless the user explicitly asks. Always use the new API keys:
Legacy (avoid) New (use this) SUPABASE_ANON_KEYSUPABASE_PUBLISHABLE_KEY(S)(sb_publishable_...)SUPABASE_SERVICE_ROLE_KEYSUPABASE_SECRET_KEY(S)(sb_secret_...)Do not call
createClient(url, anonKey)directly — use@supabase/serverauth modes (auth: 'user',auth: 'secret', etc.) which handle key resolution automatically. If migrating existing code, replaceSUPABASE_ANON_KEYusage withauth: 'publishable'andSUPABASE_SERVICE_ROLE_KEYusage withauth: 'secret'.
Server-side utilities for Supabase. Handles auth, client creation, and context injection so you write business logic, not boilerplate.
