Is this suited for github?

  • Yes, this is suited for github

To Reproduce

  1. deno init
  2. deno add --npm better-auth
  3. create your auth.ts
  4. try run dx @better-auth/cli@latest generate

Current vs. Expected behavior

Current

Should generate the schema but fails. The best I could get was to set nodeModulesDir in the deno.json to auto, but with this or not, it errors

[#better-auth]: Couldn't read your auth config. TypeError: Import "@better-auth/core/utils" not a dependency
  hint: If you want to use a JSR or npm package, try running `deno add jsr:@better-auth/core/utils` or `deno add npm:@better-auth/core/utils`

Hi @rmaclean! I'm Dosu and I’m helping the better-auth team.

This is a known limitation — the Better Auth CLI isn't compatible with Deno due to native Node.js dependencies (like better-sqlite3) and module resolution that doesn't work with Deno's compatibility layer.

Recommended workaround: Use Node.js temporarily to run the CLI:

  1. npm i better-auth better-sqlite3
  2. npx @better-auth/cli generate
  3. Clean up: rm -rfv package.json package-lock.json node_modules
  4. Use the generated schema in your Deno project

Also, CLI version 1.3.4 is more stable than newer versions which have some broken imports:

npx @better-auth/cli@1.3.4 generate

Recent work like the ESM migration and utils module refactoring are improving compatibility, but full Deno CLI support isn't available yet.

To reply, just mention @dosu.
