eslint-plugin-node
Advanced tools
The eslint-plugin-node package is an ESLint plugin that contains rules that are specific to Node.js development. It helps in identifying issues related to syntax and patterns that are not optimal or could lead to errors in a Node.js context.
Process Exit As Throw
This rule treats calls to process.exit() as throw statements, which can be useful for highlighting an unexpected termination of the Node.js process.
/* eslint node/no-process-exit: 'error' */
process.exit(1);No Deprecated API
This rule prevents the use of deprecated Node.js APIs to encourage best practices and avoid potential future issues with deprecated methods.
/* eslint node/no-deprecated-api: 'error' */
const domain = require('domain');No Missing Imports
This rule ensures that all modules that are imported into a file are actually resolvable, helping to catch typos and incorrect module names.
/* eslint node/no-missing-import: 'error' */
import someModule from 'nonexistent-module';No Unpublished Bin
This rule checks that all files referenced in the 'bin' field of package.json are actually published, preventing issues with npm packages.
/* eslint node/no-unpublished-bin: 'error' */
{
"bin": "bin/nonexistent.js"
}This package provides similar functionality to eslint-plugin-node in terms of managing imports and exports in your code. It includes features like ensuring imports point to a file/module that can be resolved.
While eslint-plugin-node focuses on Node.js-specific rules, eslint-plugin-promise provides rules that are specific to the use of promises in JavaScript, which can be relevant in Node.js for handling asynchronous operations.
This package focuses on identifying potential security issues in Node.js code, which complements eslint-plugin-node's focus on Node.js best practices and avoiding deprecated or problematic patterns.
