v1.0.0

Breaking Changes

• The first and only argument to the Miniflare constructor is now an object. Scripts should be specified via the script option for strings and the scriptPath option for files:

  // Previous version
  import vm from "vm";
  import { Miniflare } from "miniflare";
  
  const mf1 = new Miniflare(
    new vm.Script(`addEventListener("fetch", (event) => { ... })`),
    { kvPersist: true }
  );
  const mf2 = new Miniflare("script.js", { kvPersist: true });

  // New version
  import { Miniflare } from "miniflare";
  
  const mf1 = new Miniflare({
    script: `addEventListener("fetch", (event) => { ... })`,
    kvPersist: true,
  });
  const mf2 = new Miniflare({
    scriptPath: "script.js",
    kvPersist: true,
  });

• The Miniflare.getNamespace method has been renamed to Miniflare.getKVNamespace

• Logged errors will now throw a MiniflareError if no log is provided

• When using file system KV persistence, key names are now sanitised to replace special characters such as :, /, and \. Reading keys containing these characters may now return null if a value was stored in the previous version.
