dialyzer-integration

Dialyzer integrates into CI/CD by running static analysis checks in GitHub Actions or GitLab CI workflows. Set up a PLT (Persistent Lookup Table), then add a step that runs `mix dialyzer` to catch type errors before deployment, ensuring consistent analysis across your team's builds.

Dialyzer is a static analysis tool for Elixir and Erlang that detects type errors and discrepancies without running code. It uses success typing to find bugs early in development, reducing runtime failures and improving code reliability across your project.

Create a PLT file with `mix dialyzer --plt` once, then run `mix dialyzer` on subsequent checks to analyze only changed code. This speeds up local iteration by reusing cached type information instead of re-analyzing your entire codebase.

Yes. Configure Dialyzer in VS Code or Vim to display type warnings inline, and add pre-commit hooks that run `mix dialyzer` before commits. Both approaches give immediate feedback without waiting for CI, catching issues during development.

Commit a shared PLT file to your repository or cache it in CI/CD. This ensures all team members and pipeline runs analyze code against identical type information, eliminating inconsistencies from local PLT differences.

Dialyzer supports both Elixir and Erlang projects since Elixir compiles to Erlang bytecode. Set up PLT and analysis the same way regardless of language, enabling type checking across mixed Erlang/Elixir codebases.
