By the way, I have a couple of tools for recruiters: a tech keyword glossary, and a job description keyword highlighter tool. Both of these tools are now updated with the new technology mentioned in the 2019 survey.
One of the most interesting results was the drop in favorable opinions on Angular (and popularity stagnation). I'll highlight it with a screenshot just showing the frontend frameworks.
FYI if you need a refresher on backend vs frontend, I have one here.
Another thing to note here is that Vue is exploding in popularity, while React has maintained and increased it's dominance. React remains the most loved frontend framework.
The next section of the survey I had to call out was about the data layer. These are the tools that are used to transfer data between the client side and the server side of an application.
Looking at the graph below is very obvious that GraphQL and Apollo are quickly becoming popular and will probably outpace the use of Redux soon! Note that Apollo is a library for working with GraphQL.
Having built large sites using both Redux with a REST API and with Apollo using a GraphQL API, I have to say that GraphQL is very nice to work with (it confers a number of technical advantages over REST) and I will be using it for most business applications going forward if I have a choice.
If you want a primer to REST vs GraphQL I have one written up here.
I've spoken to many recruiters recently who don't yet know what GraphQL is - well it's time to learn because you are going to be seeing this in job descriptions everywhere, if you aren't already!
Note that Redux continues to grow in popularity but people are starting to have a more negative opinion of it.
There were a few technologies listed for the first time this year in the survey that merit talking about. I'll list them out here and explain what they are:
