Vue began as a project of a single person, Evan You. It is amazing that it has gotten to the point where it is today: a contender for the spot of the favorite frontend framework, competing with the corporate-backed React and Angular.
Of course, these are not the only frontend frameworks, but the trio of Vue, React, and Angular seem to be the most popular, with the internet buzzing with comparisons of these frameworks and experiences with them. It's not uncommon to come across an article that compares Vue and React, for example, or a blog post on ten ways that Vue is better than Angular. Regardless of whether these articles are someone's opinion, or clickbait, or statement of the facts, there must be some truth to these claims.
What was the reason for Vue's success? Dedication, hard work, or luck? Probably a bit of each. But another key to Vue's success was Evan's obvious priority of making things easy for the developer. Vue's no longer developed by a single person, but it is still very approachable. The community has kept the gist of what Vue was all about from the beginning: an easy-to-use framework that gets out of your way and just lets you code.
Vue CLI is another example of this. Besides a command-line interface that's up to par with other modern frontend frameworks, Vue CLI 3 sets a new standard in frontend JavaScript frameworks, and comes with a graphical user interface (GUI). This interface makes it a breeze to set up, extend, run, and serve a Vue project.
When you pair this addition of a GUI with the successful attempt to ease the pain of toolchain fatigue by offering a really well thought-out setup process, you get a really powerful combination, and happy developers as a result.
