- Each workspace directory is probed for a `tsconfig.json`. - These and any that are included by their `references` are put into a list ordered by priority. - A tsconfig has lower priority than its `references`. - An earlier listed entry in `references` has higher priority than a later one. - A probed tsconfig in an inner directory has higher priority than an outer one. Their `references` would be interspersed between them. - Each tsconfig has a filter based on its `files`, `include` and `exclude` fields. If it doesn't have `files` or `include`, it will match any path in its containing directory not exempted by `exclude`. - For type-checking, each root path will be allocated compiler options based on the first tsconfig it whose filter it matches from this list. - Only if it doesn't match any tsconfig, it will fall back to using the nearest `deno.json`. If it's a workspace member and the root `deno.json` has `compilerOptions`, these will be merged using the same logic from `extends`. Inheritance between configs strictly occurs via `extends` in a `tsconfig.json`, and between workspace member and root `deno.json`s' `compilerOptions`. There is no implicit inheritance between `tsconfig.json` and `deno.json`. The default compiler options currently applied against tsconfigs are Deno's normal defaults, with the exception of `lib`. The default value for `lib` is `["deno.window", "deno.unstable", "dom"]` for files in the scope of a tsconfig with `lib` unspecified. This behaviour is depended on by, for example, the template project created by `create-vite -> svelte`. I expect we'll add more such exceptions over time with other fields. |
