JavaScript source maps

Posted by & filed under Uncategorized.

Have you ever found yourself wishing you could keep your client-side code readable and more importantly debuggable even after you’ve combined and minified it, without impacting performance? Well now you can through the magic of source maps.

Basically it’s a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location. Developer tools (currently WebKit nightly builds, or Google Chrome Canary) can parse the source map automatically and make it appear as though you’re running unminified and uncombined files. As of writing Firefox has a blocked status for Source Map support. See MozillaWiki Source Map entry for more details.

The following are links to tools that generate or maintain files in the XML Sitemaps format, an open standard defined on sitemaps.org and supported by the search engines such as Ask, Google, Microsoft Live Search and Yahoo!. Sitemap files generally contain a collection of URLs on a website along with some meta-data for these URLs. The following tools generally generate “web-type” XML Sitemap and URL-list files (some may also support other formats).
