I need create chat module for contao 2.11. Website have standard and custom modules. I need add global javascript file (load on each front end url) and html block, with I can add to each page. Best if I'll do it in my own module, without interfering in other modules or core.
I was looking for in other modules but I not found. I'm not found too any global java script tutorial.
Other question: Can you recommend some book about Contao for developers. Because probably I'll probably have to often work with contao.
Thanks in advance for any answers.
I need this information as soon as possible, that after google research I sent this post. I'm sure that somewhere in internet exist answer. But 4 hours tutorial and modules study nod solved my issue.
Regards
