I'm developing an enterprise web app with Vue.js, and I would like to use the Web Serial API in Chrome. On the linux machine that I'm developing on, I went to this Chrome flag chrome://flags/#enable-experimental-web-platform-features and enabled it. Then I did console.log('serial' in navigator) and it returned true, meaning that the flag is enabled. All is good so far.
So I went and did the same thing on the corporate computer I need to be using (running windows 10). I enabled the flag in Chrome, restarted it, and ran console.log('serial' in navigator) on the tab running the web app, but it returns false, which is bad because I need it to be true. But when I run that code on a different tab, it returns true. How could my web app be changing the navigator? So I can't use the Web Serial API on the one computer that needs to be using it and I don't know why.
Any help is appreciated.
UPDATED. The problem is not specific from vue js, you should make the script execute from a secure environment, either localhost or from a ssl secured domain. This security concerns are covered on this draft https://wicg.github.io/serial/#security.
