When you are happy, full of energy, love your job, get a lot of things to do, confident, etc - you are more attractive for any woman, especially for your wife, than when you are uncertain, unhappy, frustrated and full of problems.
Work as much as possible on yourself and your own happiness and career. Any reasonable woman is designed to feel what is going on with you.
Also consider some physical activity which you like. Gym, hiking, cycling, kayak, crossfit - whatever makes you happy and stronger and a same time does not lead to injuries
It is reasonable to try all those modern frameworks, tons of npm packages, webpack, sass, preprocessors, typescript.
And then throw this shit as far away as possible, because right now you have a beautiful javascript support in Chrome, if you need it, and you can render everything you need with React when you compile, i.e. prerender, your website.
Complexity these days is way beyond what we are ready to support. While React seems to be cool at start, in the end it, as any other framework, is a pain in the ass, 10 times bigger than any other solution
