Managing web libraries as dependencies with WebJars
James Ward of Typesafe officially launches WebJars project, with new website and support for Java web frameworks.
modern websites becoming increasingly reliant on libraries like
jQuery, Bootstrap and Backbone.js, managing these components also
becomes increasingly annoying.
“Why not do with web libraries like we now do with Java libraries and specify them as managed dependencies?” he wrote in April. “This allows us to declaratively set the version, use a consistent version across an application, and easily deal with transitive dependencies.” For example, specifying Bootstrap 2.2.1 as a dependency includes jQuery 1.8.2 automatically.
While an initial experiment was released in April, yesterday Ward launched a new site for the project, webjars.org, and released these WebJars to Maven Central. The new website also includes instructions for making WebJars compatible with web frameworks such as Play 2, Spring MVC and Servlet 3. Grails instructions are promised to be “coming soon”.
So far there are 31 libraries already available, including angularjs, ember.js and of course jQuery, and new frameworks can be requested as an issue on GitHub. Of course, keeping these libraries up-to-date is another story – but the open-source nature of the project should hopefully mean others can help contribute.
