Error "Can't find variable: Map" for app with Turf v5.1 in PhantomJS

[ath0mas]

Testing my app with PhantomJS worked well till updating Turf from v4.6 to v5.1.6 ; it now fails with ReferenceError: Can't find variable: Map for a given line in turf.min.js (custom build through turf-builder).

It seems to be kind of a known issue when Map is called inside PhantomJS as it doesn't support ES6 features.

found that the source file in v5.1 includes new Map();:

  function HashMap () {
    MapInterface.call(this);
    this.map_ = new Map();
  }

and that in v5.0 it was polyfilled:

var MapImpl = typeof Map === 'undefined' || !Map.prototype.values ? MapPolyfill : Map;
...
function HashMap() {
  /**
   * @type {Object}
   * @private
  */
  this.map_ = new MapImpl();
}

as a result, source is not pure ES5
know why this change?

That's another jsts Polyfill.

@ath0mas I'd recommend using the specific modules that you need instead of the global Turf.

We won't be publishing another global bundle until v6.x, so even if this change is patched it "should" no longer use jsts (which uses this Map polyfill).

Problem is with dep change from jsts to turf-jsts that rewrote HashMap dropping MapPolyfill

Closing; #88 is the tracking issue for JSTS.
