Reason's nature lends itself to great editor support. Most of our editor plugins provides at minimum:

• Types display.
• Programmatic code formatting through refmt.
• Errors & warnings display.
• Syntax highlighting.
• Type-driven autocomplete.
• Jump to definition.

And other features.

The OCaml Platform provides support for Reason and integrates with editors such as VSCode, Vim, or Emacs.

• For VSCode, we recommend using the vscode-ocaml-platform plugin, which offers OCaml & Reason support out of the box.
• For other editors, we recommend using a language server client plugin of your choice, and pairing it with the ocaml-lsp. Check out the respective README's to get started.

Other:

• Vim/Neovim: Make sure to use ocaml-language-server for native development as suggested. (Mac, Linux): npm install -g ocaml-language-server
• vim-reasonml: For use with esy, Reason, and Merlin (not LSP based). (Mac, Linux, Windows).
• Sublime Text
• IDEA
