It is challenging to accurately estimate the total number of Vue.js developers worldwide since there is no official registry or certification for them. However, we can estimate based on the popularity of the framework, the number of online resources available, and the number of developers who identify as Vue.js developers.
According to the State of JavaScript 2021 survey, Vue.js is the fourth most popular front-end framework after React, Angular, and Svelte. The survey also reported that 22.3% of respondents had used Vue.js, and 63.5% would use it again. This indicates a significant and growing community of developers who are using Vue.js.
Regarding online resources, Vue.js has a large and active community, with many resources available, including official documentation, tutorials, videos, and forums. These resources attract developers to the framework and support their learning and development.
