ASP.NET Core doesn't provide a native bundling and minification solution. For set up instructions and sample projects, see WebOptimizer. ![]() Choose a bundling and minification strategyĪSP.NET Core is compatible with WebOptimizer, an open-source bundling and minification solution. Greater performance gains are realized when using bundling and minification with assets transferred over a network. The load time shows a significant improvement, however this example ran locally. The total bytes sent metric saw a significant reduction when bundling. The following table outlines differences between individually loading assets and using bundling and minification: Actionīrowsers are fairly verbose regarding HTTP request headers. In addition to removing the comments and unnecessary whitespace, the following parameter and variable names were renamed as follows: Original Common side effects of minification include shortening variable names to one character and removing comments and unnecessary whitespace.Ĭonsider the following JavaScript function: AddAltToImg = function (imageTagAndImageID, imageContext) The result is a significant size reduction in requested assets (such as CSS, images, and JavaScript files). Minification removes unnecessary characters from code without altering functionality. This results in improved first page load performance. Fewer files mean fewer HTTP requests from the browser to the server or from the service providing your application. You can create any number of individual bundles specifically for CSS, JavaScript, etc. Bundling reduces the number of server requests that are necessary to render a web asset, such as a web page. Bundlingīundling combines multiple files into a single file. In this case, bundling and minification provide a performance improvement even after the first page request. Additionally, the browser requires a validation request for each asset. If the expires header isn't set correctly on the assets and if bundling and minification isn't used, the browser's freshness heuristics mark the assets stale after a few days. So, bundling and minification don't improve performance when requesting the same page, or pages, on the same site requesting the same assets. Once a web page has been requested, the browser caches the static assets (JavaScript, CSS, and images). Used together, bundling and minification improve performance by reducing the number of server requests and reducing the size of the requested static assets.īundling and minification primarily improve the first page request load time. What is bundling and minificationīundling and minification are two distinct performance optimizations you can apply in a web app. JSON minifying is useless if not used in a website or database context.This article explains the benefits of applying bundling and minification, including how these features can be used with ASP.NET Core web apps. After half an hour of web search, I only found a python minifier (not un-minifier), and nothing that can be use as a stand-alone that could permit a user to use my batch without installing weird developers language on his machine. EXE and called by MS-DOS batches, feel free to say it.īut I'm pretty sure you can't, because this is a technology used by webdevs and mainly proposed as online services where you can copy your code and obtain the minified result in the page, or JS scripts that can be implemented in web projects. Now if you know a JSON parser that can be used in Windows as a. ![]() I don't want to parse JSON, I never had too before the recent JSON minifying decided by the dev team. How the hell can you come and just say "don't use MS DOS to parse JSON" ? That wasn't the topic. Not mentioning that the line is HUGE and MS-DOS limits variables to ~8190 characters, so I can't even process the line. This is called a program, that program relies on reading files containing several lines : now that JSONs are minified, there is a single line, and to detect things in that line I have to parse it (when I didn't have to before). This program does many things, like reading a file, evaluating its number of lines, calculating how it could process the next operations in several batches at the same time, open the file again with all the batches launched wich individually read a portion of the JSON, and then detect some peculiar parts of lines, and modify them (wich in itself requires some special and distinct operations). I don't understand you answer : I'm using MS DOS as a programming language, to make a program.
