[IMPORTANT] Enable "Take Over Mode"

In coc-volar, please enable and use "Take Over Mode". Check the Vue.js documentation for more information on "Take Over Mode".

• https://vuejs.org/guide/typescript/overview.html#volar-takeover-mode

If you want to use the "TypeScript Vue Plugin" instead of Take Over Mode, install typescript-vue-plugin in your project (npm install typescript-vue-plugin). After installation, add a setting in tsconfig.json to use typescript-vue-plugin.

If you are using "Take Over Mode" for the first time in your project

1. To begin, open the *.vue, *.ts, *.js, *.tsx, *.jsx file.
2. Then run :CocCommand volar.initializeTakeOverMode.
3. The .vim/coc-settings.json file will be created in the "project root".
   • The "volar.takeOverMode.enabled": true and "tsserver.enable": false settings will be added.
4. coc.nvim will be restarted and the settings will be reflected.

If you want to disable Take Over Mode for a project

Delete the .vim/coc-settings.json file in the "project root", and start Vim again.

VitePress and petite-vue support

Notes for make VitePress, petite-vue project working with Volar.

VitePress

• Set volar.vueserver.vitePress.processMdFile to true in .vim/coc-settings.json.
  • [WARNING] If you use this setting, it is recommended to enable it at the workspace (project) level.
• vue is optional add in devDependencies for better intellisense.
• Make sure added related .md files path to tsconfig.json include property.

petite-vue

• Set volar.vueserver.petiteVue.processHtmlFile to true in .vim/coc-settings.json.
  • [WARNING] If you use this setting, it is recommended to enable it at the workspace (project) level.
• Set html.enable to false in .vim/coc-settings.json.
• vue is optional add in devDependencies for better intellisense.
• Make sure added related .html files path to tsconfig.json include property.

Recommended additional installation: "watchman"

coc-volar uses the fileEvents option to watch files in the project, it is recommended to install watchman.

• 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, 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', 'vue.config.js', 'nuxt.config.ts']

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