how to customize custom component based on role ?
What is the best way to customize a custom component to be visible to only some users with some specific roles ??

You can use below code in your custom component with this function to re-use in areas.
<#function user_has_role (id, roles)> <#assign liql = "SELECT id FROM users WHERE roles.name IN (${roles}) and id = '${id}'" /> <#assign query = rest("2.0","/search?q=" + liql?url) /> <#if (query.status == "success") && query.data.size gt 0> <#return true> <#else> <#return false> </#if> </#function>and call it like this:
<#if user.registered && user_has_role(user.id,"'Administrator', 'Developer'")> ... </#if>
Parshant This works great for me! But I would like to also PREVENT a link from showing up for a certain role. Could you help me with that? I'm showing Software Notifications to anyone with role "CARRIER_CUSTOMER" - how can I hide Discussions from that same role?
<#function user_has_role (id, roles)>
<#assign liql = "SELECT id FROM users WHERE roles.name IN (${roles}) and id = '${id}'" />
<#assign query = rest("2.0","/search?q=" + liql?url) />
<#if (query.status == "success") && query.data.size gt 0>
<#return true>
<#else>
<#return false>
</#if>
</#function><a href="/t5/Discussion/ct-p/discussion">Discussions</a><br>
<a href="/t5/Product-Notices/ct-p/product-notices-doc">Product Notices</a><br>
<#if user.registered && user_has_role(user.id,"'Administrator'")>
<a href="/t5/Software-Notifications/ct-p/software-notifications">Software Notifications</a><br>
</#if>Your code should be,
<#function user_has_role (id, roles)> <#assign liql = "SELECT id FROM users WHERE roles.name IN (${roles}) and id = '${id}'" /> <#assign query = rest("2.0","/search?q=" + liql?url) /> <#if (query.status == "success") && query.data.size gt 0> <#return true> <#else> <#return false> </#if> </#function> <#if user.registered && user_has_role(user.id,"'CARRIER_CUSTOMER'")> <#else> <a href="/t5/Discussion/ct-p/discussion">Discussions</a><br> </#if> <a href="/t5/Product-Notices/ct-p/product-notices-doc">Product Notices</a><br> <#if user.registered && user_has_role(user.id,"'CARRIER_CUSTOMER'")> <a href="/t5/Software-Notifications/ct-p/software-notifications">Software Notifications</a><br> </#if>
Is there any way where i can avoid making this rest call to fetch roles?? Some predefined function which returns me roles??
No, there is no other way then this for custom component.
If you are using in custom page for a category, then you can set the role permission to the whole page.
Something like this should work:
<#list restadmin("/users/id/${user.id?c}/roles").roles.role as role><#if role.name?? && (role.name == "Administrator")>
