Bumps mustache from 3.2.1 to 4.0.0.

Changelog

Sourced from mustache's changelog.

[4.0.0] / 16 January 2020

Majority of using projects don't have to worry by this being a new major version.

TLDR; if your project manipulates Writer.prototype.parse | Writer.cache directly or uses .to_html(), you probably have to change that code.

This release allows the internal template cache to be customised, either by disabling it completely or provide a custom strategy deciding how the cache should behave when mustache.js parses templates.

const mustache = require('mustache');
// disable caching
Mustache.templateCache = undefined;
// or use a built-in Map in modern environments
Mustache.templateCache = new Map();

Projects that wanted to customise the caching behaviour in earlier versions of mustache.js were forced to override internal method responsible for parsing templates; Writer.prototype.parse. In short, that was unfortunate because there is more than caching happening in that method.

We've improved that now by introducing a first class API that only affects template caching.

The default template cache behaves as before and is still compatible with older JavaScript environments. For those who wants to provide a custom more sopisiticated caching strategy, one can do that with an object that adheres to the following requirements:

{
  set(cacheKey: string, value: string): void
  get(cacheKey: string): string | undefined
  clear(): void
}
