DTS Resolver

[sxzz]

rolldown-plugin-dts will require a DTS resolver capable of resolving types from both dependencies and relative TS files, in order to inline and bundle types.

The resolver's behavior should match that of the ts.resolveModuleName API in TypeScript. For reference, see the unit tests here: https://github.com/sxzz/dts-resolver/blob/ce9a1d1ea34ccabca10a275144e34012b9879eda/tests/index.test.ts#L101-L123

Currently https://github.com/sxzz/dts-resolver is using Oxc Resolver to simulate this behavior and there are lots of edge cases, like

• Tsdown doesn't bundle types for pg rolldown/tsdown#306
• Tsdown doesn't bundle types for trpc server and some other popular libs rolldown/tsdown#303
• tsdown fail to bundle d.ts rolldown/tsdown#238
• Should prefer the types entry during resolution. sxzz/dts-resolver#3
