Runflower

Write basic data handling code as arrays of strings.

It's a way to get around environments that do not allow eval or new Function. User should be familiar with _.flow and functional programming ideas.

Available function libraries

• lodash/fp
• understory
• prairie

Usage

import _ from 'lodash/fp'
import { evaluate } from 'runflower'
 
const createString1 =  _.flow(
  _.over([_.constant('/cape-io/'), _.get('url.subdomain'), _.get('pathname')]),
  _.join(''),
)
 
const createString2 = evaluate([
  ['over', [['constant', '/cape-io/'], ['get', 'url.subdomain'], ['get', 'pathname']]],
  ['join', ''],
])
const createString3 = evaluate([
  { over: [{ constant: '/cape-io/' }, { get: 'url.subdomain' }, { get: 'pathname' }] },
  { join: '' },
])
const info = { url: { subdomain: 'dev' }, pathname: '/index.html' }
 
console.log(createString1(info) === createString2(info)) // => true
console.log(createString1(info) === createString3(info)) // => true
 

With YAML you can write things like:

---
flow:
 - get: data
 - map:
    flow:
      - get: price
      - add: 10
