Coc.nvim: Disable TSServer for Flow files

[camflan]

Describe the bug
Attempting to get only Flow working on flow files, as the tsserver is reporting syntax errors specific to ts type annotations vs flow annotations

To Reproduce
Open flow typed files, see tsserver errors.

I've re-added the neovim-languageclient plugin (I had removed it prior to installing Coc) configured the "languageservers" section of the config file and added

"coc.tslint.enable": false,
"coc.tsserver.enable": false,

to my coc config and it still shows tsserver errors in addition to my flow errors.

Expected behavior
I would see flow errors, not tsserver errors

Screenshots

Desktop (please complete the following information):

• Terminal: Terminal.app v2.8.2
• Tmux: v2.7

"coc.tslint.enable": false,
"coc.tsserver.enable": false,

They're not valid configurations, they won't work, try

yarn global add vscode-json-languageserver

to get completion support for coc-settings.json.

You can disable tsserver by create file .vim/coc-settings.json in the folder of your flow project, and add configuration:

{
  "tsserver.enableJavascript": false
}

[camflan]

Oh, weird. I have the vscode-json-languageserver installed, that's how I got those keys in cot-settings

I also have "tsserver.enableJavascript": false in my $HOME/.vim/coc-settings.json file. Do I also need this in _each_ of my flow projects?

here's my coc-settings.json for reference,

{
    "coc.preferences.autoTrigger": "trigger",
    "coc.preferences.timeout": 300,
    "coc.tslint.enable": false,
    "coc.tsserver.enable": false,
    "coc.tsserver.enableJavascript": false,
    "languageserver": {
        "reason": {
            "command": "ocaml-language-server",
            "args": ["start", "--stdio"],
            "filetypes": ["reason"],
            "initializationOptions": {},
            "settings": {}
        },
        "flow": {
            "command": "flow-language-server",

            "initializationOptions": {},
            "settings": {}
        }
    }
}

[chemzqm]

Do I also need this in each of my flow projects?

Not needed.

"coc.tsserver.enableJavascript": false,

should be

"tsserver.enableJavascript": false,

The json language server use snippet feature, it's better to use confirm to get the completion result, so bind <cr> to <C-y> is recommanded:

  inoremap <expr> <cr> pumvisible() ? "\<C-y>" : "\<C-g>u\<CR>"

Another tip is not type " before completion, just type tslint and type <cr> to select.

[chemzqm]

Fix needed for json extension to avoid such miss leading completion.

[danielo515]

But, disabling tsserver like this will also turn off other features like variable renaming, right?

[sushantdhiman]

"javascript.validate.enable": false works for me
