Automatic Error Reporting Tool JavaScript in Proxino of YC incubator project

Another YCombinator incubator project attracts the attention of a large number of Web developers: Proxino, a new service that allows developers to detect errors on all their Javascript clients, you do not need to manually check the error code.

Unlike Python, JavaScript code is executed in a local web browser. In this way, you can quickly respond and have good results, but there is also a drawback: if some users encounter problems, developers need to spend a lot of time to check. The Code executed by each browser is different. If a bug occurs, the developer cannot automatically receive the bug report.

There are several ways to solve this problem. Developers can create their own test components to automatically check various situations in various browsers. They can also package exception handling programs through their code. But the founders of Proxino say this test method is not perfect. The worst bug is the bug that can be detected by these hackers. Many developers do not want to manually add these exceptions.

Proxino is useful. Developers use the Proxino proxy server to upload their Javascript applications. The Proxino will use code to check each part of these applications and generate an exception report. If a user's browser encounters a problem, they can get ping at any time. This proxy can also reduce the download time and cache JavaScript applications to further increase the speed. They also automatically convert other languages.

 

Of course, the proxy server also has a potential drawback: if the server crashes, your application may also crash, and you cannot directly control the operation to continue. To solve this problem, Proxino uses a backup technology. Once they are down, you can directly start these applications from the local server.

There are already many tools that can help optimize JavaScript, such as Google's closure compiler, but they say there are not enough good tools for developers to check for errors in browsers, their cross-platform service rivals have different performances on different browsers, such as Webkit and Opera.

Proxino charges fees based on the traffic of your website. For low-traffic websites with a PV of less than 1000 per month, they provide a free version. The monthly PV fee is USD 30. For more detailed price list, see here ).

They seem to have an ambitious long-term plan to serve Javascript around the world.
