Using the Microsoft Ajax Minifier from the Command Line
After
you install the Microsoft Ajax Minifier, you can use the tool from the command
line. Open the Microsoft Ajax Minifier Command Prompt from the Microsoft Ajax
Minifier program group. Next, enter the name of an input file and the name of an
output file like this:
ajaxmin test.js -o test.min.js
The Microsoft Ajax Minifier will report how much it was able to minify the file
(for example, 43%).
You also can use the Microsoft Ajax Minifier to
minify Cascading Style Sheet files. You use the same syntax:
ajaxmin test.css -o test.min.css
Using the Microsoft Ajax Minifier as a Build Task
You can
integrate the Microsoft Ajax Minifier into your Visual Studio Build process.
Every time you perform a build in a Visual Studio ASP.NET project, you can
minify all of your JavaScript and Cascading Style Sheet files automatically.
You can use the Ajax Minifier with both ASP.NET Web Forms and ASP.NET
MVC Web Application Projects (WAPs). However, you cannot use the minifier with
ASP.NET Web Forms Websites.
Follow these steps:
2. Within Visual Studio, right-click your project in the Solution Explorer
window and select the menu option Unload Project
3. Select the menu option Edit project name
4. Add the
following code immediately above the closing <project> tag:
01.<Import Project="$(MSBuildExtensionsPath)\Microsoft\MicrosoftAjax\ajaxmin.tasks" />
02.<Target Name="AfterBuild">
03.<ItemGroup>
04. <JS Include="**\*.js" Exclude="**\*.min.js;Scripts\*.js" />
05.</ItemGroup>
06.<ItemGroup>
07. <CSS Include="**\*.css" Exclude="**\*.min.css" />
08.</ItemGroup>
09.<AjaxMin
10. JsSourceFiles="@(JS)" JsSourceExtensionPattern="\.js$" JsTargetExtension=".min.js"
11. CssSourceFiles="@(CSS)" CssSourceExtensionPattern="\.css$" CssTargetExtension=".min.css" />
12.</Target>
5. Right-click
your project in the Solution Explorer window and select the menu option
Reload Project
After you complete these steps, all of the CSS and
JavaScript files in your project will be minified whenever you do a build
automatically. The minified files will not appear in the Solution
Explorer window. To see the minified files, you must select the menu option
Project, Show All Files.
Using the Microsoft Ajax Minifier with Source Control
The
Microsoft Ajax Minifier generates the minified JavaScript and CSS files as the
output of the build process. For this reason, we recommend that you handle the
minified files in exactly the same way as you would handle the assemblies
generated by the build process. In particular, we recommend that you do not
include the minified files in your Visual Studio project and that you do not
check the minified files into source control.
If you include the minified
files in your project, and you use source control, then you will encounter
problems. When files are checked out of source control, they are checked out
with their read-only attributes set. If you attempt to do a build, the Microsoft
Ajax Minifier will generate an error when it attempts to write to a read-only
file.
