Nvim LSP Use ESLint: A Comprehensive Guide

Are you a developer looking to enhance your coding experience with Neovim and ESLint? If so, you’ve come to the right place. In this detailed guide, I’ll walk you through the process of setting up Neovim Language Server Protocol (LSP) with ESLint, providing you with a seamless coding experience. Let’s dive in!

Understanding Neovim LSP and ESLint

Before we get started, let’s clarify what Neovim LSP and ESLint are.

• Neovim LSP: Neovim LSP is a Language Server Protocol (LSP) client for Neovim, an advanced text editor. It allows you to leverage the power of LSP to enhance your coding experience, providing features like code completion, on-the-fly error checking, and more.
• ESLint: ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code. It helps you enforce a consistent code style and catch potential bugs early in the development process.

Now that we have a clear understanding of both Neovim LSP and ESLint, let’s move on to setting them up together.

Prerequisites

Before you begin, make sure you have the following prerequisites installed:

• Neovim: Download and install Neovim from here.
• Node.js: ESLint requires Node.js to run. You can download and install it from here.
• Python: Some Neovim LSP extensions require Python. You can download and install it from here.

Setting Up Neovim LSP

Now that you have the prerequisites installed, let’s set up Neovim LSP.

1. Open your Neovim configuration file (usually located at ~/.config/nvim/init.vim or ~/.nvim/init.vim) in your favorite text editor.
2. Install the nvim-lspconfig plugin by adding the following line to your configuration file:

Plug 'neovim/nvim-lspconfig'

3. Save the configuration file and restart Neovim.
4. Install the Language Server you want to use (e.g., pyright for Python, typescript-language-server for TypeScript, etc.) by running the following command in your terminal:

pip install pyright

Repeat this step for each Language Server you want to use.

Setting Up ESLint

Now that you have Neovim LSP set up, let’s integrate ESLint.

1. Install ESLint by running the following command in your terminal:

npm install eslint --save-dev

2. Initialize ESLint by running the following command in your terminal:

./node_modules/.bin/eslint --init

This command will guide you through setting up your ESLint configuration file (usually located at .eslintrc or .eslintrc.json).

Integrating ESLint with Neovim LSP

Now that you have both Neovim LSP and ESLint set up, let’s integrate them.

1. Install the eslint.nvim plugin by adding the following line to your Neovim configuration file:

Plug 'sainh/eslint.nvim'

2. Install the required dependencies by running the following command in your terminal:

pip install eslint

3. Restart Neovim.
