Setup the test projectīegin by creating a very simple Node project in a blank directory. In short, ESLint is the de facto for static analysis and Prettier has quickly become the go-to tool for formatting code. By focusing primarily on the formatting rules, Prettier can do more sophisticated things under the hood, but due to being opinionated doesn't require time fine-tuning these style rules. Prettier's sole specialisation is to handle formatting of code and it does this job extremely well. But we will rely on ESLint purely to help alert us to problematic code and defer the format handling to Prettier. It's true that ESLint could very well handle both the code quality errors and syntax format violations. This means ESLint can help us find problematic code before we commit to version control and (more importantly) before the code finds its way onto Production. What is ESLint?ĮSLint - the pluggable linting utility for JavaScript and JSXĬode linting is a form of static analysis that will find both code errors as well as highlight syntax not adhering to formatting styles. Prettier currently supports JavaScript (including ES2017), JSX, Flow, TypeScript, CSS, LESS, SCSS, JSON and GraphQL. It is particularly advantageous when working on projects in teams. Prettier is an opinionated code formatterĪ tool that will format code against some opinionated and standard default formatting rules to ensure all final code maintains a consistent style. Code -install-extension dbaeumer.vscode-eslintĬode -install-extension esbenp.prettier-vscodeĬhange VSCode settings to include "editor.formatOnSave": true, to automatically format on save.
