Are the frameworks good enough? : A study of performance implications of JavaScript framework choice through load- and stress-testing Angular, Vue, React and Svelte

Sammanfattning: The subject of JavaScript frameworks/libraries and which to choose as a developer, organization or client has been the target of quite some research, and even more debate. This thesis aims to investigate four of these, namely Angular, React, Svelte and Vue by building a functionally identical application and running performance tests towards them through Apache JMeter to measure throughput. Furthermore, Webdriver plugin will be added to measure full render response times to add another dimension to the discussion. The result of the investigation shows that even if some of the tests speak very highly in favor of some of these frameworks/libraries, some do not, and adding in previous research into perceived values as well as performance metrics of these frameworks make the picture even more complex. Furthermore, the frameworks/libraries in question evolve very rapidly, constantly contending against each other. What this study does, in the end, is to provide a basic method of comparison that can be extended, which will aid stakeholders in researching the frameworks/libraries strengths and weaknesses as well as which framework that fits their project’s needs.
