Custom ESLint Rules for Advanced JavaScript Linting
Article Introduction:Custom ESLint rules are required because standard rules cannot override all project-specific conventions, such as prohibiting specific functions outside the component, forcing API request comments, variable naming constraints, etc. 1. Create an ESLint plug-in structure, including the entry index.js and the rule file directory; 2. Write rule logic, listen to nodes through AST and implement checking logic, such as detecting function calls; 3. Register plug-in in ESLint configuration and enable rules. Common applications include controlling the location of function calls, forcing comments, and restricting import paths. It is recommended to use ASTExplorer to assist in development and pay attention to performance and debugging methods.

Implementing Custom ESLint Rules for JavaScript
Article Introduction:Custom ESLint rules can unify code style and reduce bugs. First, understand the rules structure of ESLint based on AST and write detection logic, such as prohibiting the use of console.log; second, create a rule file in the project and configure .eslintrc.js to refer to the rules; finally, pay attention to the familiarity of AST structure, avoid false positives and missed reports, optimize performance and improve configurability. Through these three steps, custom rules can be implemented and integrated to improve team development efficiency and code quality.

What is ESLint
Article Introduction:ESLint is a static code inspection tool for JavaScript and JSX, which is mainly used to discover potential problems in the code and unify the code style. It not only checks for syntax errors, but also points out non-standard, prone to errors or in compliance with best practices based on configuration rules. Its core functions include: discovering common errors in advance (such as unused variables), unifying the code style, cooperating with the editor's real-time prompts, and supporting automatic fixes of some problems. The steps for use are: install ESLint, create configuration files, select rulesets, run check commands, and use them with the editor plug-in. Coping strategies include: adopting loose configurations to gradually strengthen rules, closing unwanted rules, and integrating in CI/CD to ensure uniform use of the team. Through reasonable configuration,

Creating Custom ESLint Rules for Your Project
Article Introduction:Create custom ESLint rules first and configure them. eslintrc.js is loaded through require or local plug-in; 2. Write rules to define meta and create functions, check code patterns through AST traversal, such as prohibiting import of specific paths; 3. Use eslint-rule-tester to write test cases to ensure that rules behave correctly in valid and invalid code; 4. Use AST deep analysis to implement advanced functions, such as restricting function calls, naming specifications or environment variable access; 5. Make rules reusable through schema configuration, and support sharing across projects in private npm packages or monorepo, ultimately implementing automated enfo of team coding specifications
