Node App Template

You require only remove unnecessary code modules.

Tools:

• Node.js 10.13
• yarn 1.12.3
• TypeScript 3.3
• TS-Lint
• typeorm 0.2.9 (any dbms + migrations)
• ts-typed-events as strongly typed event emitters
• ts-node-dev for autoreload while developing
• node-dev for autoreload in production (this also allows autoreload of config files)
• Use decko's @memoize facility
• @machinomy/logger
• coveralls

Testing

• jest 23.6.0
• newman for testing REST services based on Postman 6.5.2 files

Hint: Use BigInt from ES instead of BigNumber. Node 10.4+ & Chrome 67+ supports it.

Hint: Do "yarn global add yarn-completions" for yarn run completions (https://github.com/mklabs/yarn-completions)

Hint: Develop with yarn start-dev, run in production with yarn start

Databases

To use Postgres instead of SQLite just rename ormconfig.json to ormconfig.sqlite.json and ormconfig.postgres.json to ormconfig.json

pify

Converts callback to promise. Usage:

  import { pify } from './util/pify'
  
  const result = await pify<string>((cb: (error: Error, signedData: string) => void) => {
    web3.eth.sign(address, data, cb)
  })

TODO Make pify usage more simple
