Update

• Backport File.webkitRelativePath property for better types compatibility with native FormData

• Backport improvements for instanceof checks on File object: It now will recognize File-ish objects and Files as File instance, but not Blob or Blob-ish objects:

  Old behaviour:

  import {Blob, File} from "formdata-node"
  
  const file = new File(["File content"], "file.txt")
  const blob = new Blob()
  
  file instanceof Blob // -> true
  file instanceof File // -> true
  
  blob instanceof Blob // -> true
  blob instanceof File // -> true
  
  const fileLike = {
    [Symbol.toStringTag]: "File",
    name: "file.txt",
    stream() { }
  }
  
  const blobLike = {
    [Symbol.toStringTag]: "Blob",
    stream() { }
  }
  
  fileLike instanceof Blob // -> true
  fileLike instanceof File // -> true
  
  blobLike instanceof Blob // -> true
  blobLike instanceof File // -> true

  New behaviour:

  import {Blob, File} from "formdata-node"
  
  const file = new File(["File content"], "file.txt")
  const blob = new Blob()
  
  file instanceof Blob // -> true
  file instanceof File // -> true
  
  blob instanceof Blob // -> true
  blob instanceof File // -> false
  
  const fileLike = {
    [Symbol.toStringTag]: "File",
    name: "file.txt",
    stream() { }
  }
  
  const blobLike = {
    [Symbol.toStringTag]: "Blob",
    stream() { }
  }
  
  fileLike instanceof Blob // -> true
  fileLike instanceof File // -> true
  
  blobLike instanceof Blob // -> true
  blobLike instanceof File // -> false

• Backport File values normalization for better alignment with the spec. FormData instances will store Files added via .set() and .append() methods as is.

  Old behaviour:

  import {FormData, File} from "formdata-node"
  
  const file = new File(["File content"], "file.txt")
  const form = new FormData()
  
  form.set("file", file) // will create a new File, then store that new object
  form.get("file") === file // -> false
  
  form.set("file", file, "renamed-file.txt") // will also create a new File (with the new name), then store that new object
  form.get("file") === file // -> false

  New behaviour:

  import {FormData, File} from "formdata-node"
  
  const file = new File(["File content"], "file.txt")
  const form = new FormData()
  
  form.set("file", file) // will store this File instance as is
  form.get("file") === file // -> true
  
  form.set("file", file, "renamed-file.txt") // will create a new File (with the new name), then store that new object
  form.get("file") === file // -> false

All changes: v4.3.3...v4.4.0
