Code breaks after upgrading from v3.4.6 to v6.0.0

when upgrading from v3.4.6 to v6.0.0, my javascript code breaks

TypeError: Cannot read property ‘map’ of undefined

I’ve tracked down that the fuse.search() is returning undefined after upgrading, when before the upgrade.

import Fuse from 'fuse.js'

export default function filterRecipeList(searchValue, recipesToSearch) {
  var options = {
    shouldSort: true,
    tokenize: true,
    threshold: 0.3,
    location: 0,
    distance: 100,
    maxPatternLength: 32,
    minMatchCharLength: 1,
    keys: ['id', 'name', 'ingredients.name']
  }

  console.log(recipesToSearch)
  console.log('handleRecipeSearch options: ' + options)
  
  var fuse = new Fuse(recipesToSearch, options) // "list" is the item array
  console.log('handleRecipeSearch searchValue: ' + searchValue)
  
  var result = fuse.search(searchValue)
  console.log('handleRecipeSearch result: ' + result)

  return result
}

Any Ideas? Does it have anything to do with my node.js version?

Okay, I figured it out. The search results are now wrapping each item in an object under key item. So to get it to work as before you need to do something like `results = results.map(i => i.item);

This is actually mentioned in the changelog, without saying what was actually changed about the search results. The trick here is apparently this library doesn’t show breaking changes in major version updates, but in each of the beta updates, so you need to read through all of the many beta updates to pick up on breaking changes.

Yes. This is my bad. I failed to update the changelog. Will be more disciplined moving forward.
