eslint-utils2

在 eslint-utils 基础上优化 ReferenceTracker ，以支持通配符，例如：

import { ReferenceTracker } from "eslint-utils";

export default {
  meta: {},
  create(context) {
    return {
      "Program:exit"() {
        const tracker = new ReferenceTracker(context.getScope());
        const traceMap = {
          // Find `console.*` .
          console: {
            [ReferenceTracker.SingleLevelWildcard]: {
              [ReferenceTracker.READ]: true,
            },
          },
          // Find `Object.prototype.**.bind()` .
          Object: {
            prototype: {
              [ReferenceTracker.MultiLevelWildcard]: {
                bind: {
                  [ReferenceTracker.CALL]: true,
                },
              },
            },
          },
        };

        for (const { node, path } of tracker.iterateGlobalReferences(
          traceMap
        )) {
          context.report({
            node,
            message: "disallow {{name}}.",
            data: { name: path.join(".") },
          });
        }
      },
    };
  },
};

🏁 Goal

This package provides utility functions and classes for make ESLint custom rules.

For examples:

• getStaticValue evaluates static value on AST.
• ReferenceTracker checks the members of modules/globals as handling assignments and destructuring.

📖 Usage

See documentation.
