SDK from CypherWallet for DAPP Developers to easliy onboard thier new users with necessary tokens

• TypeScript 4
• Optionally esbuild to bundle for browsers (and Node.js)
• Linting with typescript-eslint (tslint is deprecated)
• Testing with Jest (and ts-jest)
• Publishing to npm
• Continuous integration (GitHub Actions / GitLab CI)
• Automatic API documentation with TypeDoc

Inject the CypherWallet Signon-SDK from the CDN link https://public.cypherd.io/js/onboardingsdk.js

<script src="https://public.cypherd.io/js/onboardingsdk.jss"> </script>
window.Cypher({
  address: '0xdEc1bc71bf91431D60eF2742f412DCd1c5A204B8', // user wallet address
  targetChainIdHex: '0x5', // Required: Chain Id in Hexadecimal
  requiredTokenBalance: 1, // Required: Token Value Required with respect to native currency or token value
  isTestnet: true, // Optional: enable testnet for developer testing
  callBack: (success) => { // Optional
    if(){
      console.log('User wallet has a necessary token or currency');
    }else{
      console.log('Failed to load user wallet necessary token or currency');
    }
  } //
});

1. Install the singon-sdk npm i -S @cypher
2. Import the Cypher into Code

# Install dependencies
npm install

# Now you can run various yarn commands:
npm run cli
npm run lint
npm run test
npm run build-all
npm run ts-node <filename>
npm run esbuild-browser
...

• For publishing to npm, use npm publish

esbuild is an extremely fast bundler that supports a large part of the TypeScript syntax. This project uses it to bundle for browsers (and Node.js if you want).

# Build for browsers
yarn esbuild-browser:dev
yarn esbuild-browser:watch

# Build the cli for node
yarn esbuild-node:dev
yarn esbuild-node:watch

You can generate a full clean build with npm run build-all (which uses both tsc and esbuild).

• package.json includes scripts for various esbuild commands

• esbuild has a --global-name=xyz flag, to store the exports from the entry point in a global variable. See also the esbuild "Global name" docs.

• esbuild for the browser uses the IIFE (immediately-invoked function expression) format, which executes the bundled code on load (see also evanw/esbuild#29)

You can write Jest tests

import { greet } from './main'

test('the data is peanut butter', () => {
  expect(1).toBe(1)
});

test('greeting', () => {
  expect(greet('Foo')).toBe('Hello Foo')
});

Run the tests with yarn test, no separate compile step is necessary.

• See also the Jest documentation.
• The tests can be automatically run in CI (GitHub Actions, GitLab CI): [.github/workflows/lint-and-test.yml], [.gitlab-ci.yml]
• Take a look at other modern test runners such as ava, uvu and tape

You can auto-generate API documentation from the TypeScript source files using TypeDoc. The generated documentation can be published to GitHub / GitLab pages through the CI.

Generate the documentation, using src/main.ts as entrypoint (configured in package.json):

yarn docs

The resulting HTML is saved in docs/.

You can publish the documentation through CI:

• GitHub pages: See [.github/workflows/deploy-gh-pages.yml]
• GitLab pages: .gitlab-ci.yml

• tsconfig docs
• esbuild docs
• typescript-eslint docs
