ESLint vs. PostCSS vs. Semgrep vs. Vue.js Comparison Chart

ESLint is a static code analysis tool for identifying problematic patterns in JavaScript code. It allows developers to configure rules and define custom ones, addressing both code quality and coding style issues. ESLint supports current ECMAScript standards and experimental syntax from future drafts. It can process code using JSX or TypeScript through appropriate plugins or transpilers. The tool is integrated into most text editors and can be part of continuous integration pipelines, enabling automatic problem detection and correction. ESLint is the #1 JavaScript linter by downloads on npm and is used at companies like Microsoft, Airbnb, Netflix, and Facebook. Preprocess code, use custom parsers and write your own rules that work alongside ESLint's built-in rules. Customize ESLint to work exactly the way you need it for your project. Many problems ESLint finds can be automatically fixed. ESLint fixes are syntax-aware so you won't experience errors.

Modern security teams are “paving the road” for developers — enforcing code guardrails on every commit. r2c’s Semgrep can eliminate vulnerability classes organization-wide. Scale your security team with lightweight static analysis. Semgrep is a fast, open-source, static analysis tool that excels at expressing code standards — without complicated queries — and surfacing bugs early in the development flow. Precise rules look like the code you’re searching; no more traversing abstract syntax trees or wrestling with regexes. Start right away with 900+ rules and SaaS infrastructure to get fast results in your editor, at commit-time, or in CI. When off-the-shelf rules aren’t enough, quickly and intuitively write custom rules to express your unique code standards. Rules look like the code you’re searching. For example, rules for Go look like Go. Find function calls, class or method definitions, and more without having to understand abstract syntax trees or wrestle with regexes.
