sort-class-members

Enforce alphabetical sorting of class members.

Targeted pattern scope​

This rule inspects ClassBody members and checks alphabetical order of member names.

Supported sortable keys:

  • identifier keys (foo)
  • string literal keys ("foo")

Members with unsupported/computed names are skipped.

What this rule reports​

This rule reports the first class member that appears out of alphabetical order.

Why this rule exists​

Alphabetical member ordering can reduce merge conflicts and make large classes more predictable to scan.

❌ Incorrect​

class Example {
 zebra(): void {}
 alpha(): void {}
}

✅ Correct​

class Example {
 alpha(): void {}
 zebra(): void {}
}

Deprecated​

Behavior and migration notes​

This rule is deprecated in favor of dedicated sorting plugins.

Options​

This rule has no options.

Status​

Additional examples​

class Tokens {
 "a-token" = "#000";
 "z-token" = "#fff";
}
// ✅ valid

class WithComputed {
 [dynamicKey](): void {}
 alpha(): void {}
}
// computed member names are not directly sortable by this rule

ESLint flat config example​

import etcMisc from "eslint-plugin-etc-misc";

export default [
 {
  plugins: { "etc-misc": etcMisc },
  rules: {
   "etc-misc/sort-class-members": "error",
  },
 },
];

When not to use it​

Disable this rule if class member order is semantic (lifecycle grouping, public/private sections) rather than lexical.

  • Start at warning level in CI, then move to error after cleanup.
  • Use focused codemods/autofix batches per package or directory.
