---

All changes: v2.0.0...v2.0.1

2.0.0

Breaking

• Drop CommonJS support. The package is now ESM only;
• Remove Encoder from exports;
• Remove deprecated isFormDataLike helper. Use isFormData instead.

Update

• Minimal required Node.js version is 14.18;
• Headers in FormDataEncoder.headers property can be accessed in case-insensitive manner. TypeScript users still have correct TS typings, but only for original and lowercased keys (for example Content-Type and content-type);
• FormData instance will be preserved in array inside of FormDataEncoder instance (previously it held a reference to given FormData instance);
• Deprecate isFileLike helper. Use isFile instead;
• Deprecate FormDataEncoder.getContentLength() method. The content-length is now static value, so this method makes no sense. Use FormDataEncoder.contentLength or FormDataEncoder.headers["content-length"] instead.

Add

• Expose FormDataEncoderHeaders type.

All changes: v1.6.0...v1.7.0

1.6.0

Add

• Add options argument for FormDataEncoder constructor;
• Add support for per part Content-Length header. It turned off by default, because it is not spec-compliant extension - the web clients does not include it. Use enableAdditionalHeaders option to enable this header:

import {Readable} from "stream"

import {FormDataEncoder} from "form-data-encoder"
import {FormData, File} from "formdata-node"

const form = new FormData()
const file = new File(["My hovercraft is full of eels"], "file.txt", {type: "text/plain"})

form.set("field", "Some field")
form.set("file", file)

// You can pass options as the second or third argument
const encoder = new FormDataEncoder(form, {enableAdditionalHeaders: true})

Readable.from(encoder).pipe(process.stdout)

Outputs:

--form-data-boundary-ZrZBNwvvIVAsVl6f
Content-Disposition: form-data; name="field"
Content-Length: 10

Some field
--form-data-boundary-ZrZBNwvvIVAsVl6f
Content-Disposition: form-data; name="file"; filename="file.txt"
Content-Type: text/plain
Content-Length: 29

My hovercraft if full of eels
--form-data-boundary-ZrZBNwvvIVAsVl6f--
