As far as the language goes, Julia is absolutely awesome for general purpose work, including web development, scripting, glue language, etc.

The associated libraries are, unfortunately but understandably, less well developed than counterparts in other languages. E.g. right now I'm happily using AWS[Core/SQS/S3], which are highly functional community developed AWS packages, but they're definitely less full featured than boto3. My impression is this situation is common for a variety of web and database packages.

Ah, yea if you're ok with that then great. I like it myself. A lot of folks are dismayed by that though. I find that the language itself has the ease of Python with the performance of a language with static (or is it strong?) types, JIT, and a design focused on performance. The REPL functionality and package manager are pretty good too.
