Vue Language Features (Volar) extension for coc.nvim

Install

:CocInstall @yaegassy/coc-volar

scoped packages

Note

• coc-volar version v0.35.0 and later uses vue-language-server version v2.x.x. If you have coc-typescript-vue-plugin installed, please uninstall it as it will cause conflicts and errors.
  • :CocUninstall @yaegassy/coc-typescript-vue-plugin
• To utilize various language features such as IntelliSense, Diagnostics, and more in the <script> blocks of Vue files, you need to install either coc-tsserver or coc-tsserver-dev.
  • :CocInstall coc-tsserver or :CocInstall coc-tsserver-dev
  • Note: coc-volar checks if coc-tsserver or coc-tsserver-dev are installed in the environment when opening a Vue file. If they are installed, coc-volar automatically starts tsserver.

[RECOMMENDED] Additional installation of "watchman"

In the @vue/language-server used by coc-volar, it utilizes the workspace/didChangeWatchedFiles notification to watch files within the project.

In coc.nvim, it is recommended to install watchman in order to utilize this feature.

• See: https://github.com/neoclide/coc.nvim/wiki/Using-coc-extensions

If you have difficulty installing watchman, you can use coc-volar without watchman, but you may not be able to immediately use volar's IntelliSense with the newly added files.

In this case, please execute the command to restart the language server.

• :CocRestart

workspaceFolders

Depending on the project like mono repo or how Vim/Neovim is started, workspaceFolders may not be recognized correctly.

If workspaceFolders are not recognized correctly, the language server may parse unnecessary project folders, etc., slowing down the operation. Or Language Server may not work properly.

The default configuration of coc.nvim resolves to the directory where the .git, .hg, or .projections.json files reside as the workspace root.

coc-volar has also already added vite.config.ts, vite.config.js, vue.config.js or nuxt.config.ts to the extension side to resolve workspace root.

If further customization is needed, set b:coc_root_patterns in ".vimrc/init.vim".

Example:

  au FileType vue let b:coc_root_patterns = ['.git', '.env', 'package.json', 'tsconfig.json', 'jsconfig.json', 'vite.config.ts', 'vite.config.js', 'vue.config.js', 'nuxt.config.ts']

For more information, check this coc.nvim's wiki.
