What is the correct version of node necessary to build this

[BitLox]

Describe the bug No documentation is given as to what the build environment should be set at Could the devs PLEASE take 5 minutes of their time to relay to us what they used to build the releases?

To Reproduce Try building from the instructions on the main page. Invariably, some sort of error. Farthest I ever got was getting to npm run start and then it died in a flurry of TypeScript errors. Here, built with node 10.16.2 as in the CI file:

npm i
npm run apply:bitpay
npm run start

Then we get this:

[00:22:38]  ionic-app-scripts 3.2.3 
[00:22:38]  watch started ... 
[00:22:38]  build dev started ...

Expected behavior Project should build as described.

Desktop (please complete the following information):

• OS: macOS 13.1 (22C65)
• Browser: Safari
• node: 6,7,8,9,10,11,12,13,14,16,19

Smartphone (please complete the following information): Never got to this phase

Additional context I based a previous project off this code and it has performed well. Sadly, now that I want to update the project it seems this is verging on abandonware.

Are there ANY combinations of OS / Environment that are verified building?

I'd really like to contribute but am very frustrated with this.

I would be happy to contribute an extensively documented guide to building this but just need some info please. (Yes I saw the circleci specifies 10.16.2 - it still does not work)
