The Complete ServiceNow Developer Course

Yes, there are any number of free resources online to get you started. I also recommend this course on Udemy (I have no affiliation with this guy).

This course covers the most common client and server side APIs that you will need to know. I found it really helpful when I was first getting started.

As others have said, it's not there,and some devs see that as a major drawback of the platform.

Development packaging /deployment support is built-in in the platform. I'd like to echo what u/bsquinn said - if you have experienced devs, they need to rethink their expectations or they'll a) become frustrated (we've had developers leave) or b) screw stuff up which will bite you in the butt later when you do want to deploy.

Important things to note: When you're developing on a dev instance, all developers are working on the same environment. If you like, the most immediate for of Continuous Integration - everything the devs do is already on the integration platform. Side-effects from overlapping development ("commit wars") are immediately visible.

Make sure you're working in the correct update set! This cannot be stressed enough. Update Sets are a good(ish) mechanism for staging from dev to test to production. But not if you mix them up and splatter your changes all over multiple update sets. Make a strategy for update sets (one per story? one per work package? one per sprint?) and stick with it. And be sure to cleanse your update sets before deploying from dev to anywhere else. Lots of unwanted changes wind up in update sets. Little tests, stuff that you maybe didn't want to deploy, everything is tracked and ends up in the update set.

Inversely - some stuff does NOT end up in an update set by default, even though you see it as part of the development. This can be extremely frustrating and time-consuming. Make sure before deployment you go through the stuff you want to deploy, check it's in the update set, and if not, add it manually. As a rule, ServiceNow does not put stuff into Update Sets that it considers "data". Infuriatingly, this can also include things like dashboards, widgets, dashboard layouts, pages, etc.

If you want to prepare, check out udemy.com - an online course portal. There are some very affordable courses there. The ServiceNow Dev basics course is, right now, USD 9.99: https://www.udemy.com/course/servicenow-201-development/ That's a great deal! You get all the video lessons, a discussion board around the content (not very much used, though) and can go back and rewatch many times. I found these courses to be a very good introduction when I started out.

I'm currently doing the Udemy course The Complete ServiceNow Developer Course. I think it normally costs about £50 but Udemy often discount their courses, so I got the course for £15. One thing to note is that the course does assume some basic knowledge of Javascript. Oh and congratulations on passing your CSA- it is not easy!

If it helps, I am a certified developer and implementer. You should follow the council above re: use the free source material. There are also EXCELLENT Udemy courses I am sure ServiceNow would like you to not see:

Also, before you dive too deep into working with the platformanswering the following question:

“What is ServiceNow?”

Try answering without all the marketing and sales noise. Try giving a concise answer that would help an average person understand what ServiceNow is. Notably, I couldn’t answer it properly until I made the change to think like a developer. If you start with the correct answer to this question, everything else you learn makes a lot more sense.

Note: ServiceNow themselves can’t answer it.
