# v3 Roadmap



## General stuff



- [x] **BREAKING:** Drop support for Node.js 4 and Node.js 6 (#489, #624)

- [x] Update devDependencies (related to #489)

- [x] When users clone(), automatically create streams with custom highWaterMark (#386, PR open: #671)

- [x] Bundle TypeScript types (Support for TypeScript without need of installing `@types/node-fetch` package) (#669)

- [x] Replace Rollup with Microbundle (#643)

- [x] Introduce linting to the project (#303)

- [x] Simplify Travis CI build matrix (related to #431) - Dropping support for Node.js 4 & 6 will help

- [x] Response.statusText should not default (#578)

- [x] Use w3c defined message for AbortError (#657)

- [x] URL is not encoded as UTF-8 (#245)

- Deprecate timeout in favor of AbortController (#523)

- [x] Data URI support (#659)

- [x] Drop the optional dependency on encoding and move charset detection into a separate package. (In progress: [Richienb/fetch-charset-detection](https://github.com/Richienb/fetch-charset-detection) (PR Open: #694))

- [x] Drop existing blob implementation code and use fetch-blob as dependency instead (https://github.com/bitinn/node-fetch/issues/668#issuecomment-529175627)

- [x] Fix stream piping (#309, PR open: #670)

- [x] Fix stream resolving (#642, #665)

- [x] Do not use constructor.name to check object (#667, PR open: #673)

- [x] Properly forward request errors while piping response stream

- [x] Convert `Content-Encoding` to lowercase (#661, PR open: #672)

- [x] More tests for data URI (https://github.com/bitinn/node-fetch/issues/668#issuecomment-529175096)

- [ ] Drop credentials before redirection (#274)

- [x] Modernise the code behind FetchError and AbortError (https://github.com/bitinn/node-fetch/issues/668#issuecomment-530845161)

- [x] Propagate size and timeout to cloned response (#664)

- [x] Replace the calls to `url.parse` and `url.resolve` with calls to `new URL` to use the new UTF-8 awareness and remove the `utf8` package.

    - [x] `url.parse` (https://github.com/node-fetch/node-fetch/pull/701)

	- [x] `url.resolve` (https://github.com/bitinn/node-fetch/commit/e3cd4d22c3f1871fb41b17035ac83b47ad57fdf6)

- [ ] Document types of fetch errors more thoroughly (#549)

- [ ] Should update host if there's a redirection (#570, PR Open: #596)

- [x] **High priority** doesn't correctly handle multiple `content-type` values (#783)



## Additional:



- [ ] HTTP/2 support (#342, PR open: #796)

- [ ] Plugin/middleware system (https://github.com/bitinn/node-fetch/issues/668#issuecomment-533544800, PR open: #677)

- ~~WebStream API support (#387)~~ - needs more discussion and standard.

- ~~Support trailers (#330)~~ - trailer support has been removed (whatwg/fetch#772).

- ~~Caching (#68)~~ - would likely require opinionated implementation.

- ~~Cookies (#94)~~ - would likely require opinionated implementation.



## Other



- [x] Enable Dependabot to automatically update dependencies if they pass tests and are within an appropriate version range.

- [x] A way to back/sponsor the project (#680)

- ~~Create a final v2 release before releasing v3~~

- [ ] Update upgrade guide

- [ ] Release v1.x version of [Richienb/fetch-charset-detection](https://github.com/Richienb/fetch-charset-detection) before release.

- [ ] Add this package to [DefinitelyTyped/DefinitelyTyped/master/notNeededPackages.json](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/notNeededPackages.json) since we now ship the typings.
