Pack Examples

Basic usage

  let subObject = 'Spam'
    let o = { 'SpamA': 1, 'SpamB': 2, 'anonAbc prefixB': 0 }
    let newObject = pack({
        object: o,
        filterFn: (k) => k.startsWith(subObject),
        subobjectName: subObject
    })

Output: { 'anonAbc prefixB': 0, Spam: { SpamA: 1, SpamB: 2 } }

Using the renameKeyFn param

  let subObject = 'Spam'
    let o = { 'SpamA': 1, 'SpamB': 2, 'anonAbc prefixB': 0 }
    let newObject = pack({
        object: o,
        filterFn: (k) => k.startsWith(subObject),
        subobjectName: subObject,
        renameKeyFn: renameKeyWrapper(removePrefix, { prefix: subObject })
    })

Output: { 'anonAbc prefixB': 0, Spam: { A: 1, B: 2 } }
