Bilibili’s front‑end team built a custom “mirror” SDK and full‑stack monitoring platform that captures JavaScript and resource errors, detects white‑screens, logs user behavior offline, routes data through Kafka‑ClickHouse pipelines to visual dashboards, and provides one‑click alerts, now serving over 1,700 projects across 85% of business lines.
This article explains what source maps are, details their JSON structure, demonstrates how to generate them with Vite and Webpack, discusses choosing appropriate devtool options for development and production, and shows how to make them work in browsers, Sentry, and manual mapping.
Ctrip’s automated error warning solution for its WeChat mini‑programs provides a comprehensive pipeline that injects build IDs, collects runtime errors via SDK, maps them with source maps, aggregates data in an APM MySQL store, and delivers real‑time alerts across development, testing, and production stages.
This article presents a complete solution for routing Sentry error and performance data to the correct micro‑frontend projects in a Qiankun architecture by intercepting transport, redistributing URLs, and distinguishing transaction types, with detailed code examples for both Sentry 6.x and 7.x versions.
This article explains why JavaScript error monitoring is essential for web stability, describes techniques for capturing global errors, unhandled promise rejections, and user interaction context, and outlines advanced practices such as source‑map de‑obfuscation, error aggregation, and automated blame assignment to streamline debugging.
This guide walks developers through selecting Sentry, deploying it with Docker, configuring alerts, managing quotas, and integrating the platform into Flutter (as well as other languages), offering practical tips and solutions to common installation issues.
This guide introduces Sentry's open‑source error and performance monitoring platform, outlines how to set up and extend the service, and details its event‑processing architecture, including Relay, Redis caching, Symbolicator, and alert handling via Celery and Kafka.
The article explains how integrating Source Maps—generated by modern bundlers and automatically uploaded via a Webpack plugin—into iQIYI Hawkeye’s front‑end exception monitoring restores original file names and line numbers for minified production JavaScript errors, enabling rapid debugging despite bundle‑size and versioning challenges.
This guide walks through adding Sentry to a frontend project—explaining core concepts, Docker deployment, environment‑specific integration, webpack source‑map uploading, alert rule configuration, ownership assignment, webhook/GitLab extensions, and common pitfalls such as URL prefix handling and HTTPS DSN setup.
This article explains the complete workflow for implementing SourceMap‑based exception monitoring across web and cross‑platform systems, covering transformer, bundler, minifier, runtime support, log collection, error deobfuscation, and the limitations of SourceMap in debugging and performance contexts.
This article walks through designing and implementing a lightweight front‑end monitoring platform that captures JavaScript runtime and compile‑time errors, Promise rejections, resource loading failures, and network request issues, while also recording user interactions, page navigation, and environment details using modular code and browser APIs.
This article presents a comprehensive design for a WeChat Mini Program frontend error monitoring system, covering background challenges, architectural and process design, SDK implementation, reporting mechanisms, and a visualized backend to help developers quickly locate and resolve runtime exceptions.
This article presents a practical case study of front‑end error monitoring for a real‑estate broker web site, detailing the background problem, pain points, analysis, design adjustments, code implementations, data collection, reporting strategies, and the resulting improvements in issue‑resolution efficiency.
Front‑end monitoring must capture JavaScript runtime errors, resource loading failures, unhandled promise rejections, and asynchronous request issues using window.onerror, error event listeners, unhandledrejection handlers, and fetch/XHR wrappers, while also handling framework‑specific hooks and cross‑origin script restrictions through CORS or manual try‑catch reporting.
Learn how to set up Django to automatically email error logs for both request and non‑request failures by configuring email settings, LOGGING handlers, and creating a reusable decorator, complete with code examples and screenshots of the monitoring results.
This guide shows how to set up Django's email backend and logging configuration to automatically send detailed error reports for both HTTP requests and custom tasks, using simple settings changes and a reusable decorator for comprehensive system monitoring.
This guide explains why front‑end error collection is essential, outlines effective methods such as using window.addEventListener('error', true), details the types of exceptions to monitor—including script errors, resource load failures, HTML hijacking, and CSS issues—and provides practical code snippets for reporting and handling them.
The article reviews Liulishuo's 2016 engineering experiments, covering their base library choices, componentization for consumer apps and internal tools, mock data generation, unit testing, error monitoring with Sentry, deployment using shipit‑deploy, and outlines goals for improving performance, testing coverage, and robustness in the coming year.
