consistent-assert-style

📝 Enforce a consistent truthiness assertion style.

💼🚫 This rule is enabled in the ✅ recommended config. This rule is disabled in the ☑️ unopinionated config.

🔧 This rule is automatically fixable by the --fix CLI option.

assert(value) and assert.ok(value) are aliases. This rule enforces one form.

The default is assert.ok(value): explicit and consistent with the rest of the assert API (strictEqual, match, throws, ok). If you prefer the shorter alias, set style: 'assert'.

This rule only targets callable imports from node:assert, node:assert/strict, assert, and assert/strict. It ignores t.assert.ok(value), because t.assert is not callable.

If you set style: 'assert', do not also enable eslint-plugin-unicorn's consistent-assert, which enforces assert.ok(value).
