#### Why not isomorphic-fetch?
-My preferred library used to be [isomorphic-fetch](https://github.com/matthew-andrews/isomorphic-fetch) but it has this [bug](https://github.com/matthew-andrews/isomorphic-fetch/issues/125) that prevents it from running in a react native environment. It seems it will never be fixed since the author hasn't been committing for more than a year. That means dependencies are outdated as well.

- /**
- * Creates a `lodash` object which wraps `value` to enable implicit method
- * chain sequences. Methods that operate on and return arrays, collections,
- * and functions can be chained together. Methods that retrieve a single value
- * or may return a primitive value will automatically end the chain sequence
- * and return the unwrapped value. Otherwise, the value must be unwrapped
- * with `_#value`.
- *
- * Explicit chain sequences, which must be unwrapped with `_#value`, may be
- * enabled using `_.chain`.
- *
- * The execution of chained methods is lazy, that is, it's deferred until
- * `_#value` is implicitly or explicitly called.
- *
- * Lazy evaluation allows several methods to support shortcut fusion.
- * Shortcut fusion is an optimization to merge iteratee calls; this avoids
- * the creation of intermediate arrays and can greatly reduce the number of
- * iteratee executions. Sections of a chain sequence qualify for shortcut
- * fusion if the section is applied to an array and iteratees accept only
- * one argument. The heuristic for whether a section qualifies for shortcut
- * fusion is subject to change.
- *
- * Chaining is supported in custom builds as long as the `_#value` method is
- * directly or indirectly included in the build.
- *
- * In addition to lodash methods, wrappers have `Array` and `String` methods.
- *
- * The wrapper `Array` methods are:
- * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
- *
- * The wrapper `String` methods are:
- * `replace` and `split`
- *
- * The wrapper methods that support shortcut fusion are:
- * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
- * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
- * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
- *
- * The chainable wrapper methods are:
- * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
- * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
- * `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
- * `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
- * `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,
- * `dropRightWhile`, `dropWhile`, `extend`, `extendWith`, `fill`, `filter`,
- * `flatMap`, `flatMapDeep`, `flatMapDepth`, `flatten`, `flattenDeep`,
- * `flattenDepth`, `flip`, `flow`, `flowRight`, `fromPairs`, `functions`,
- * `functionsIn`, `groupBy`, `initial`, `intersection`, `intersectionBy`,
- * `intersectionWith`, `invert`, `invertBy`, `invokeMap`, `iteratee`, `keyBy`,
- * `keys`, `keysIn`, `map`, `mapKeys`, `mapValues`, `matches`, `matchesProperty`,
- * `memoize`, `merge`, `mergeWith`, `method`, `methodOf`, `mixin`, `negate`,
- * `nthArg`, `omit`, `omitBy`, `once`, `orderBy`, `over`, `overArgs`,
- * `overEvery`, `overSome`, `partial`, `partialRight`, `partition`, `pick`,
- * `pickBy`, `plant`, `property`, `propertyOf`, `pull`, `pullAll`, `pullAllBy`,
- * `pullAllWith`, `pullAt`, `push`, `range`, `rangeRight`, `rearg`, `reject`,
- * `remove`, `rest`, `reverse`, `sampleSize`, `set`, `setWith`, `shuffle`,
- * `slice`, `sort`, `sortBy`, `splice`, `spread`, `tail`, `take`, `takeRight`,
- * `takeRightWhile`, `takeWhile`, `tap`, `throttle`, `thru`, `toArray`,
