I went from being contacted once a day to once every two weeks. Market is definitely colder than it used to be. Much colder. Part of me thinks it's gonna stay like that for some time, some of the weakest profiles may even have to change line of job entirely as the entry level got much higher.
This is what happened in the early 2000s. (ie, dot-com bust)
During the boom, companies were shoving warm bodies in chairs for those who could spell HTML, and paying them great money. People were coming from everywhere to get in on it.
Then it crashed, and those who couldn't cut it went back to car sales or whatever they did before. Those with chops mostly hung on and built the next phase of the market. (I was doing ColdFusion at the time, which was an easy language to learn. Those who were one-trick ponies suffered, and I regularly heard from "ColdFusion Developers" who were desperate as the one-trick rodeos went away)
I'm sorry to say, but if you're just a "front-end dev" you're probably in the same boat. Left a career to do a bootcamp? You may want to start calling those old colleagues.
(not saying this applies to OP necessarily, but I'm just an "old" dev who's seen this before)
