Jetbrains Elixir [ 2026 Release ]

Example: find all Enum.map(..., fn x -> x end) and replace with Enum.map(..., & &1) . This pattern-based refactoring is unique to JetBrains.

In VS Code: Manually search-replace, or use LSP rename (which often misses references in umbrella children due to path misconfiguration). Risk of broken code. jetbrains elixir

VS Code highlights type warnings from Dialyzer. JetBrains requires external tool or manual Dialyzer run. Example: find all Enum

VS Code: Debug adapter more reliable; inspect large terms with #inspect . However, initial launch configuration ( launch.json ) is more manual. Risk of broken code

Phoenix LiveView (real-time HTML) is better supported in VS Code due to Tailwind CSS, HTML, and HEEx template tooling. JetBrains handles .heex but with less polish.

IntelliJ: Set breakpoint in handle_call . Run mix debug . Variables show in UI, but inspection of state map sometimes truncates large values. Stepping into :gen_server internal code is possible but verbose.

Elixir developers often work with PostgreSQL (via Ecto). IntelliJ’s database console and VCS annotate (blame) work seamlessly with Elixir files. 4.2 Where ElixirLS/VS Code Wins 1. Macro expansion on demand ElixirLS can show the expanded macro output by compiling the module. JetBrains does not offer this – a significant gap for advanced metaprogramming.
