ContextLines | Sentry for Next.js

Import name: Sentry.contextLinesIntegration

This integration adds source code from inline JavaScript of the current page’s HTML (e.g. JS in <script> tags) to stack traces of captured errors. It can’t collect source code from assets referenced by your HTML (e.g. <script src="..." />).

The ContextLines integration is useful when you have inline JS code in HTML pages that can’t be accessed by Sentry’s backend, for example, due to a login-protected page.

import * as Sentry from "@sentry/browser";

Sentry.init({
  dsn: "___PUBLIC_DSN___",
  integrations: [Sentry.contextLinesIntegration()],
});

Options

frameContextLines

Type: number

The number of lines to collect around each stack frame’s line number. Defaults to 7.
