Here are settings I am using in the first project to make it look "traditional" ES5 projectA/.prettierrc.json 1
Prettier tries to enforce the same code style without 100s of options, thus there are just a few settings you can change. So when I edit projectA/.prettierrc.json file, I get intelligent tooltips. In fact, VSCode understands the Prettier configuration file format via the built-in json schema. I like using JSON configuration format so my code editor helps me.
In my example I have two subfolders, and there is a configuration file in each subfolder: 1
Npm install -save-dev -save-exact prettierĪt the root of the project create the Prettier configuration file. I assume you are using NPM and have package.json file inside the repository. In reality, each of your repos will have its style I am using subfolders in order to keep the example simple. The demo repo bahmutov/prettier-config-example has two subfolders, each with its distinct code style, enforced by Prettier. Not every project uses the same code style, thus it is important to respect the style of whatever project you are currently working in. When setting up Prettier it is important to configure it per-project. format the changed files on Git commit before committing them.format the file from VSCode every time I save it.I prefer to use two solutions described in this blog post: You can use Prettier from command line, or from your code editor whenever you paste or save a file. The code just magically gets to the format you pick. By using Prettier your team skips ALL disagreements about spacing, variable declarations, semi-colons, trailing commas, etc. It takes whatever copy/pasted code snippets you put into your file and makes it look the same as the rest of the code. Prettier reformats your JavaScript code consistently and (arguably) in way that is easy to read and understand. VSCode + ESLint + Prettier + TypeScript setup.You can find the sample project with different Prettier settings configured per-subfolder at bahmutov/prettier-config-example.
This blog post shows how to configure Prettier to work from command line, from VSCode and from Git hooks. This allows you to get a consistent formatting without thinking or arguing about it. In order to use ESLint in Visual Studio Code, you should install the ESLint extension available in Visual Studio Code’s marketplace.You can configure JavaScript code auto-formatting with Prettier to work per-project. ? What format do you want your config file to be in? JavaScriptĪt this point, you will have a new project with package.json and. ? Where does your code run? Browser, Node ? Which framework does your project use? None of these ? What type of modules does your project use? JavaScript modules (import/export) For the needs of this tutorial, you will need to have ESLint installed and configured.Īnswer the prompt with the following choices: ? How would you like to use ESLint? To check syntax and find problems There are various linters for different languages and types of projects. This tutorial was verified with Node v16.6.2, npm v7.21.0, eslint v7.32.0, and Visual Studio Code v1.59.1.
Node.js installed locally, which you can do by following How to Install Node.js and Create a Local Development Environment.
Download and install the latest version of Visual Studio Code.If you would like to follow along with this article, you will need: In this tutorial, you will install ESLint, construct rules, and enable codeActionsOnSave in Visual Studio Code. Your workflow may benefit from performing frequent lint checks to address small issues over time rather than addressing many large issues that may delay deploying code. Visual Studio code can support linting on every save. This will spare you from manually checking for indentation or using single quotes or double-quotes. These rules can be automated and enforced with linters. Style guides allow us to write consistent, reusable, and clean code.
