@next/next/no-assign-module-variable

The bundler gives every file a module object, and the code Next.js adds for hot reloading uses it. If you declare a variable named module, it hides that object, which can break the build or hot reloading.

The rule reports var, let, const and using declarations of module, anywhere in the file. It doesn't report parameters, destructuring, or an assignment to the existing module.

Configure

Off by default. To turn it on:

[lint.rules]
"@next/next/no-assign-module-variable" = "error" # or "warn"

Examples

Reported:

const module = await import("./charts.js");
module.render();

Not reported:

const charts = await import("./charts.js");
charts.render();

module.exports = { reactStrictMode: true };

function describe(module) {
  return module.id;
}
