@angular-eslint/utils
Advanced tools
@angular-eslint/utils is a utility package designed to help developers integrate ESLint with Angular projects. It provides a set of tools and utilities to facilitate linting Angular code, ensuring code quality and consistency.
Rule Creation
This feature allows developers to create custom ESLint rules tailored to their Angular projects. The code sample demonstrates how to define a custom rule that disallows a specific pattern.
const { createESLintRule } = require('@angular-eslint/utils');
module.exports = createESLintRule({
name: 'my-custom-rule',
meta: {
type: 'problem',
docs: {
description: 'Disallow certain patterns',
category: 'Best Practices',
recommended: 'error'
},
schema: [],
messages: {
forbiddenPattern: 'This pattern is not allowed.'
}
},
defaultOptions: [],
create(context) {
return {
Identifier(node) {
if (node.name === 'forbiddenPattern') {
context.report({ node, messageId: 'forbiddenPattern' });
}
}
};
}
});
AST Utilities
This feature provides utilities for working with Angular's Abstract Syntax Tree (AST). The code sample shows how to use `getTemplateParserServices` to suggest improvements for Angular templates.
const { getTemplateParserServices } = require('@angular-eslint/utils');
module.exports = {
meta: {
type: 'suggestion',
docs: {
description: 'Suggest improvements for Angular templates',
category: 'Best Practices',
recommended: 'warn'
},
schema: [],
messages: {
suggestImprovement: 'Consider improving this template.'
}
},
create(context) {
const parserServices = getTemplateParserServices(context);
return {
'Element$1'(node) {
const templateNode = parserServices.convertNodeSourceSpanToLoc(node.sourceSpan);
context.report({ node: templateNode, messageId: 'suggestImprovement' });
}
};
}
};
eslint-plugin-angular is a plugin that provides a set of ESLint rules for AngularJS applications. It focuses on AngularJS (1.x) rather than Angular (2+), making it suitable for legacy projects. Compared to @angular-eslint/utils, it does not support modern Angular features.
eslint-plugin-angularjs is another plugin aimed at linting AngularJS (1.x) code. It offers a variety of rules to enforce best practices and code quality in AngularJS projects. Unlike @angular-eslint/utils, it is not designed for Angular (2+) applications.
eslint-plugin-typescript provides linting rules for TypeScript codebases. While it is not specific to Angular, it can be used in conjunction with other plugins to lint TypeScript code in Angular projects. It does not offer Angular-specific utilities like @angular-eslint/utils.
