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.
The two tools serve different stages of the development lifecycle: VS Code/ElixirLS for rapid iteration, debugging, and macro exploration; JetBrains for large-scale code maintenance and architectural refactoring. Rather than a winner-takes-all market, the Elixir community benefits from this diversity. Future convergence via LSP adoption in JetBrains could ultimately provide developers with the best of both worlds. jetbrains elixir
VS Code highlights type warnings from Dialyzer. JetBrains requires external tool or manual Dialyzer run. Phoenix LiveView (real-time HTML) is better supported in
Example: find all Enum.map(..., fn x -> x end) and replace with Enum.map(..., & &1) . This pattern-based refactoring is unique to JetBrains. and macro exploration
