deno-nvim
A plugin to improve deno experience
Installation
using packer.nvim
use 'neovim/nvim-lspconfig'
use 'sigmasd/deno-nvim'
-- Debugging
use 'mfussenegger/nvim-dap'
Setup
This plugin automatically sets up nvim-lspconfig for deno for you, so don't do that manually, as it causes conflicts.
Put this in your init.lua or any lua file that is sourced.
Example config:
require("deno-nvim").setup({
server = {
on_attach = ...,
capabilites = ...
},
-- if you're using dap to debug (see the README for more info)
dap = {
adapter = ...
}
})
Local settings
To use local settings for each project, checkout
https://github.com/folke/neoconf.nvim which can even parse
.vscode/settings.json
The default settings are located here https://github.com/denoland/vscode_deno/blob/main/package.json
Its also recomended to install jsonls with lspconfig to get autocompletion inside the settings
Usage
deno test with code lens
use vim.lsp.codelens to activate this
Example of keybindings:
vim.keymap.set("n", "<space>dr", function()
vim.lsp.codelens.refresh();
vim.lsp.codelens.run()
end, opts)
dap support
Support debugging with https://github.com/mfussenegger/nvim-dap
Follow the instruction here https://github.com/mfussenegger/nvim-dap/wiki/Debug-Adapter-installation#javascript-deno to download and extract dapDebugServer.
Then you will need to set dap.adapter.executable.args to {dapDebugServerPath, "${port}"} when using deno.nvim.setup. (don't change "${port}" its not a place holder)
Example:
require("deno-nvim").setup {
dap = {
adapter = {
executable = {
args = {
"/absolute-path/to/js-debug/src/dapDebugServer.js", "${port}"
}
}
}
}
}
If you want to use dap outside of tests, you can add theses lines somewhere in your init.lua
-- same thing for configurations.javascript
require("dap").configurations.typescript = {
{
type = 'pwa-node',
request = 'launch',
name = "Launch file",
runtimeExecutable = "deno",
runtimeArgs = {
"run",
"--inspect-wait",
"--allow-all"
},
program = "${file}",
cwd = "${workspaceFolder}",
attachSimplePort = 9229,
},
}
auto complete import from deno registeries
deno task
Inlay Hints
Inlay hints are supported in deno from version 1.27.0, to use it install https://github.com/lvimuser/lsp-inlayhints.nvim
You can set it locally by using neoconf with these settings https://github.com/denoland/vscode_deno/blob/main/package.json#L245
You can set it globally by adding this to your init.lua where you instantiate denols server:
require "deno-nvim".setup({
server = {
on_attach = ...,
capabilities = ...,
settings = {
deno = {
inlayHints = {
parameterNames = {
enabled = "all"
},
parameterTypes = {
enabled = true
},
variableTypes = {
enabled = true
},
propertyDeclarationTypes = {
enabled = true
},
functionLikeReturnTypes = {
enabled = true
},
enumMemberValues = {
enabled = true
},
}
}
}
}
})
Now you should be able to show the hints with
require('lsp-inlayhints').toggle()
Custom useful commands
This part is WIP, currently I'm adding some commands that I personaly find useful. Feel free to open an issue or PR to improve this part. Usage `:Deno custom_command` (press Tab for completion)
Check/Update dependencies
The list of available user commands is here https://github.com/sigmaSd/deno-nvim/blob/master/lua/deno-nvim/lsp.lua#L52
Important
For the lsp to function 100% correctly you need atleast:
- nvim 0.8.0
- deno 1.26.1
More stuff
You can checkout https://github.com/sigmaSd/conjure-deno for deno repl
integration in nvim or just use iron.nvim https://github.com/sigmaSd/conjure-deno#alternative
