export const metadata = { title: subscriber-default-export-must-be-async - ESLint plugin rules, }

{metadata.title}

This rule requires the default-exported subscriber handler function to be async.

Severity

error. This rule is enabled in the recommended preset.

What it Targets

This rule targets files in your project's src/subscribers directory. It reports a default-exported subscriber handler that isn't an async function.

The following code is reported by the rule:

export default function orderPlacedHandler() {}

Instead, make the handler async:

export default async function orderPlacedHandler() {}

Why it's Important

Subscribers receive an event and are always awaited by Medusa. Making the handler async ensures Medusa can wait for its work to finish before continuing.

Fixable

This rule is auto-fixable. Run the linter with the --fix option to apply the fix automatically.
