CRA and Vite admin templates (codedthemes' berry and mantis, uilibrary's
matx) set `"baseUrl": "src"` or `"paths": { "*": ["./src/*"] }` in a
jsconfig and write every cross-file import as `layout/MainLayout`. The
import resolver took each one for an npm package: loadProjectAliases
returned null for a config with a baseUrl and no paths, and
isExternalImport classifies a bare specifier from the root config alone,
before a nested app's config is read. The imports stayed unresolved,
their names linked by bare-name matching (vite components rendering the
remix app's namesakes), and React Router routes loaded through
`lazy(() => import('views/x'))` bound to the local Loadable value.
- path-aliases: a config with only `baseUrl` loads, marked
`declaresBaseUrl`; aliasAndBaseUrlCandidates lists the most specific
`paths` pattern's targets, then the specifier read from a declared
baseUrl (paths alone never reads bare specifiers, as in TS 4.1+).
- import-resolver: a specifier isExternalImport takes for a package is
read through the importing file's own config (nearest, else the root's)
and binds only to a file the index holds (`fileExists` also answers for
folders and node_modules). A package the file's package.json or an
enclosing one declares, or a Node built-in, never binds to a project
module that way, only to a `.d.ts` the project keeps for it (#2437's
`"*": ["./typings/*"]`). A root catch-all `"*"` no longer marks every
specifier local in isExternalImport's default mode either.
- The module ref of a one-segment import (`'config'`) links the file its
specifier resolves to, as a path-shaped one already does (#2528).
- isBoundToOutOfRepoImport keeps the `extends` edge of a class whose base
is imported through baseUrl.
- importBindingTail parks a binding under its module when the app's
config maps the specifier to an indexed file, so a sync that edits the
module relinks `import Layout from 'layout/MainLayout'` and
`{ Foo as Bar }` (#2450's rule for relative imports). An undeclared name
that maps to nothing (`express` under `"baseUrl": "."`) and a declared
package keep their own tail, which root-"*" repos had lost.
- The TypeScript and TSX extension lists probe `/index.jsx` last, as tsc
does: a route resolves its lazy module as TypeScript.
Validated against main 6071c9e4 on 21 repos (wasm path): every new
import-resolved edge lands in the file its specifier names; failed
imports naming a project file go 194/190/96 -> 0 on berry/mantis/matx;
their routes bind their lazily loaded pages and layouts (matx 7 -> 21
routes); 37 + 45 cross-app JSX renders move to the app's own components.
proshop, next-saas-starter, create-t3-turbo, excalidraw and six more are
byte-identical; root-"*" repos change only parked tails plus module
links. Same deltas with stubbed node_modules. Sync after late adds and
edits equals a fresh index, except one pre-existing barrel-edit gap that
relative imports share.
