We're making a new major. \r\n\r\n\r\n\r\n\r\n\r\n## Goals\r\n\r\n- **More ergonomic API for creating procedures** and building out your backend\r\n- **CMD+Click** from your frontend and jump straight into the backend procedure. This will work with `react-query` as well!\r\n- **Better scaling** than the current structure - the TypeScript server starts choking a bit when you get close to 100 procedures in your backend\r\n- **Fully backward compatible** for the 99% use-case with a migration path which you can do incrementally. \r\n\r\n\r\n## Todos\r\n\r\n> **Important for contributors:** All of the work here is related to the [`next`](https://github.com/trpc/trpc/tree/next) branch.\r\n\r\n\r\nTracked in https://github.com/orgs/trpc/projects/1\r\n\r\n- [x] New Router API\r\n - [x] Tracked in [trpc/v10-playground](https://github.com/trpc/v10-playground) - the current winning proposal is https://github.com/trpc/v10-playground/pull/33\r\n - [x] Error formatting in new API - [`formatError()`](https://trpc.io/docs/error-formatting)-equivalent. \r\n - [x] `meta`-equivalent\r\n - [x] Maybe we need a `createRootRouter()` that additionally accepts `{ transformer: X, formatError: Y}`\r\n - [x] Implement new API in tRPC\r\n - [x] Make old routers compatible (`.legacy()` at the end to transform them to the new version)\r\n- [x] New client API with backward compatibility \r\n - Maybe old can be `client.query('postById', input, options)` whilst new stuff can be `client.queries.postById({ input, ...options})`\r\n- [x] New react-query API with backward compat\r\n- [ ] Make actual issues for all of these\r\n- [x] Add all old projects in a folder (copy/paste `examples/*` to `examples/.test` so we can track breaking changes easily and make sure we remain backward compatible for a long time\r\n- [ ] Rewrite `TRPCClient` to be functional instead of a class but reuse the same interface\r\n- [ ] Write a migration guide\r\n - [ ] New router API\r\n - [ ] New links\r\n- [x] Move transformers back to `runtime` to make it backward compatible\r\n- [ ] Explore: Add [`stripInternal`](https://www.typescriptlang.org/tsconfig#stripInternal)-flag\r\n- [x] Simplify HTTP-responses\r\n- [x] New links architecture (#1366)\r\n- [ ] Refactor observables implementation to have `unknown` errors or make it guaranteed to be `TRPCClientError` of some sort. \r\n- [ ] Make transformers dynamically opt-in similar to how a batch request is indicated by `?batch=1` maybe a transformed request could be `?transform=1` or `transform=TRANSFORMER_NAME`?\r\n- [ ] Write a blog post about new major and API.\r\n- [ ] \"Marketing\"?
