Clientlibs Qs How to exclude some js files - aem

Question

I have clientlibs with category abc. It contains multiple js files e.g.
abc
|-->JS
| |--->a.js
| |--->b.js
| |--->c.js
|-->js.txt[which have the paths of all three js files]
If I use something like : <cq:includeClientLib js="abc" />. This include all my js files in my script. But how can i restrict to include only two. These 3 are just example, there can be 10 or more. Does anyone has any idea how this can achive excluding creating new clientlib folder.
Thanks

You can achieve this requirement using themes functionality of clientlibs. It will require few modifications to the clientlibs structure. Let me explain it with three js files (a.js , b.js and c.js).
Let's assume b.js is not required all the time where as a.js and c.js are. You will have to create a parent clientlib with a.js and c.js. In the same clientlib create a theme folder and add a second clientlib with b.js [should have same category as parent], the structure should be as follows :
clientlibs: {
categories: [
"themeParent"
],
jcr: primaryType: "cq:ClientLibraryFolder",
js: {
jcr: primaryType: "nt:folder",
a.js: {
jcr: primaryType: "nt:file",
jcr: content: {}
},
c.js: {
jcr: primaryType: "nt:file",
jcr: content: {}
}
},
js.txt: {
jcr: primaryType: "nt:file",
jcr: content: {
//a.js and c.js
}
},
themes: {
jcr: primaryType: "nt:folder",
themeb: {
categories: [
"themeParent"
],
jcr: primaryType: "cq:ClientLibraryFolder",
js.txt: {
jcr: primaryType: "nt:file",
jcr: content: {
//b.js
}
},
b.js: {
jcr: primaryType: "nt:file",
jcr: content: {}
}
}
}
}
Themes can be selectively enabled for a clientlib using the themed flag of includeClientLib tag.
<cq:includeClientLib js="themeParent"/> : will include a.js , c.js and b.js
<cq:includeClientLib js="themeParent" themed="false"/> : will include a.js and c.js
<cq:includeClientLib js="themeParent" themed="true"/> : will only include b.js

You can remove the js file entry in the 'js.txt', js will be present in the path but will not be included as part of cq:include

Answer 3

To the best of my knowledge this is not possible. Whatever js file names you enter in the js.txt will be included when you write this <cq:includeClientLib js="abc" /> statement in your JSP.
So say if you want to include only two JS files in another JSP without creating a new clientlib the only way to do it is include the manually using full path.
like this
<script src="/etc/designs/projectname/clientlibs/js/a.js"></script>
<script src="/etc/designs/projectname/clientlibs/js/b.js"></script>
