Description

This module adds JavaScript and TypeScript support.

• Code completion (tide)
• REPL support (nodejs-repl)
• Refactoring commands (js2-refactor)
• Syntax checking (flycheck)
• Browser code injection with skewer-mode
• Coffeescript & JSX support
• Jump-to-definitions and references support (xref)

Module Flags

• +lsp Enables LangServer support for this module. You must have :tools lsp enabled for this to work, as well as the langserver (e.g. typescript-language-server) installed on your system.

Packages

• coffee-mode
• js2-mode
• rjsx-mode
• typescript-mode
• js2-refactor
• npm-mode
• nodejs-repl
• skewer-mode
• tide
• xref-js2*

Prerequisites

Many of this modules' plugins require node and either npm or yarn installed.

MacOS

brew install node

Arch Linux

sudo pacman --needed --noconfirm -S nodejs npm

openSUSE

sudo zypper install nodejs npm

Troubleshooting

tide-sort-completions-by-kind isn't respected

The :completion company module uses company-prescient to sort completion by frecency, which overrules specialized sorting provided by some company backends (like company-tide).
