Setup lunarvim to use prettier-eslint - lua

Question

I'm migrating to Lunarvim from Atom and I need to configure Lunarvim to use prettier-eslint for Javascript files.
Read lunarvim docs but not sure how to do it.

Answer 1

Solved with this custom LUA Config
-- optional: set your prefered indent with size
vim.opt.shiftwidth = 4
vim.opt.tabstop = 4
-- load required null-ls references
local h = require("null-ls.helpers")
local cmd_resolver = require("null-ls.helpers.command_resolver")
local methods = require("null-ls.methods")
local u = require("null-ls.utils")
local FORMATTING = methods.internal.FORMATTING
-- Define the new javascript formatter
local pe = h.make_builtin({
name = "prettier_eslint",
meta = {
url = "https://github.com/prettier/prettier-eslint-cli",
description = "Eslint + Prettier",
},
method = FORMATTING,
filetypes = {
"javascript",
"javascriptreact",
"typescript",
"typescriptreact",
"vue",
"jsx"
},
factory = h.formatter_factory,
generator_opts = {
command = "prettier-eslint",
args = { "--stdin", "--parser", "babel", "--resolve-plugins-relative-to", "~/.nvm/versions/node/v16.16.0/lib" },
to_stdin = true,
},
})
-- optional: Define a second formatter for JSON
local pejson = h.make_builtin({
name = "prettier_eslint_json",
meta = {
url = "https://github.com/prettier/prettier-eslint-cli",
description = "Eslint + Prettier",
},
method = FORMATTING,
filetypes = {
"json",
"cjson",
},
factory = h.formatter_factory,
generator_opts = {
command = "prettier-eslint",
args = { "--stdin", "--parser", "json" },
to_stdin = true,
},
})
-- Enable the the defined formatters
-- if you are using vanilla NeoVim + null-ls please
-- read how to install/enable on
-- https://github.com/jose-elias-alvarez/null-ls.nvim/blob/main/doc/CONFIG.md
local nls = require("null-ls")
nls.setup {
on_attach = require("lvim.lsp").common_on_attach,
sources = {
pe,
pejson
}
}
-- optional: LunarVim related step. Here we enable eslint as linter for Javascript.
local linters = require "lvim.lsp.null-ls.linters"
linters.setup {
{
command = "eslint",
filetypes = { "javascript" }
}
}
