I'm surprised I haven't seen nuxt (an SSR framework for Vue.js) mentioned here. It makes many of these performance enhancements out of the box. It enables some cool options, like pre-rendering static content with the generate flag. You can use it as a static site generator, or wrap dynamic stuff in a <client-only> component and only that portion will be rendered client-side. Service workers & PWA stuff, code splitting and dynamic routes, its all made pretty easy. I've been finding it quite easy to build performant front-ends with nuxt. It is opinionated, and it abstracts away the webpack config, so it certainly isn't perfect for everything. But for me, it has really been hitting a sweet spot.
