zenon.initialize(this.zenon.defaultServerUrl);

Generating address from scratch with a wallet name and password (for storage purposes)

try{
  const keyManager: KeyStoreManager = new KeyStoreManager();
  await keyManager.createNew("pass", "name");

Common issues when installing package to your project

Having issues with "crypto" or "stream" modules because of incompatibilities between server(node) and browser?

https://stackoverflow.com/questions/52530289/module-not-found-error-cant-resolve-crypto-in-opt-lampp-htdocs-angular-te

Having issues with argon2 and webpack?

antelle/argon2-browser#26
https://github.com/antelle/argon2-browser/blob/master/examples/webpack/webpack.config.js
More specific:
antelle/argon2-browser#26 (comment)

Potential problem: Error: /lib/src/wallet/manager.js 29:21 Module parse failed: Unexpected token (29:21) File was processed with these loaders: ./node_modules/@angular-devkit/build-angular/src/babel/webpack-loader.js ./node_modules/@ngtools/webpack/src/ivy/index.js ./node_modules/source-map-loader/dist/cjs.js You may need an additional loader to handle the result of these loaders.

Angular Solution:
Info here: angular/angular-cli#20471

3.1. Go to angular.json
3.2. Use the custom-webpack files from webpack-builders and add them in the root folder
3.4. Install angular-builders/custom-webpack
npm i -D @angular-builders/custom-webpack
npm i -D base64-loader
3.5. Replace current builder from angular.json like following
"projects":
  {"project-name":{
    architect:{
      build:{          
      "builder": "@angular-builders/custom-webpack:browser",
      "options": {
        "customWebpackConfig": {
          "path": "./custom-webpack.config.ts"
        },
      [...] 
      }
    }
  }
}
3.6. Add webpack
npm i webpack@5

Potential error: Error: Module not found: Error: Can't resolve 'fs' in 'D:\Projects\zenon\ts-sdk-1\examples\dist\node_modules\argon2-browser\dist'

Solution: Add this to package.json
"browser": {
  "fs": false
}

Potential error: Uncaught ReferenceError: Buffer is not defined at Function.parse (main.js:1:384593)

Solution steps: 5.1

npm i buffer

5.2 Add this to the bottom of polyfill.ts

(window as any).global = window;
global.Buffer = global.Buffer || require('buffer').Buffer;
(window as any).process = {
  version: ''
};

Potential error: main.js:1 Uncaught TypeError: Cannot convert a BigInt value to a number

Solution:

Upgrade tsconfig.json to use 
"target": "es2020",
"module": "es2020"

Potentialerror Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'wasm-eval'".

Solution: https://stackoverflow.com/questions/48047150/chrome-extension-compiled-by-webpack-throws-unsafe-eval-error
Add
devtool: 'cheap-module-source-map',
to the root of your webpack.config.js

Internal issues

Error: Error decrypting TypeError: Cannot read properties of undefined (reading 'call') at KeyStoreManager.readKeyStore (manager.js:71:1)

Solution: modifying cipher-base package in index.js Replace var Transform = require('stream').Transform with
var Transform = require('readable-stream').Transform // replacing instead of "stream"
