Path mappings are aliases that point to specific folders
If you are using Typescript (which the tag suggests you are) it’s possible to setup “path mapping” in your tsconfig.json
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@": ["./src"],
"@/*": ["./src/*"],
"@components": ["./src/components"]
}
}
}
This will create an alias for “@components” that points to a specific folder.

Other possibilities
It could be a scoped package like @types/xxx
but this is unlikely in the given case.
