Install: brew install eslint_d

About:
eslint_d.js is a persistent background server that runs ESLint in a long-lived process, eliminating the overhead of starting a new Node.js instance for each linting operation. By keeping the linter running, it dramatically reduces latency, providing near-instant feedback as you type or save files. This acceleration is particularly noticeable in large projects or when using heavy ESLint plugin configurations.

Key Features:

Persistent background server for instant linting feedback
Significantly reduces startup overhead compared to standard eslint CLI
Client-server architecture with a command-line client
Compatible with existing ESLint configurations and plugins

Use Cases:

Accelerating linting in large codebases where startup time is noticeable
Integrating with editor plugins for real-time linting without lag
Improving developer productivity in continuous feedback loops

Alternatives:

eslint – Standard CLI tool; slower for repeated invocations due to startup cost
nx – Build system with built-in caching; targets a broader scope than just linting
