So im trying to get tangleID to work to use it on a project. I am using this project.

https://github.com/TangleID/TangleID

But everytime I try and run the code i get an error message of "Mam.init is not a function".

I've tried to include the mam library as well inside then then it stops throwing an error but breaks completely by not printing out the console.log on the next line.

I found this code as well

https://gist.github.com/ender503/ecd884b07190adb79f01b0d515c3b5a3

and I'm still getting the same problem!

I'm running the sample code with following step:

  1. Create the project directory
$ mkdir tangleid-test
$ cd tangleid-test
  1. Paste the sample code to main.js.

  2. Add the @tangleid/core package.

$ yarn add @tangleid/core
  1. Run the code,
$ node main.js

If you are still getting the same problem, could you provide your Node.js version?

  • I updated NodeJS from v10 to v13.13.0 with the original code that you had wrote and it still didnt't work, I edited my post so it includes the stake trace. I did your suggestion and created a new project with your main.js and this new code is working.Thanks
