[Feature]: Support for DTS paths replacement

[chenjiahan]

What problem does this feature solve?

The compilerOptions#paths in tsconfig.json should work for DTS output.

Modern.js Module supports this, see https://github.com/web-infra-dev/modern.js/blob/main/packages/solutions/module-tools/src/utils/dts.ts#L116

• tsconfig.json:

{
  "compilerOptions": {
    "paths": {
      "rslog": ["./compiled/rslog"]
    }
  },
  "include": ["src"]
}

• src/index.ts:

import logger from 'rslog';

• dist/index.d.ts:

import logger from '../compiled/rslog';

What does the proposed API look like?

This should work out of the box.

现在 0.1.5 版本解决了值导入的别名问题，还差类型导入的别名问题没实现，加油

Not yet, you can use tsc-alias to replace alias paths with relative paths after Rslib compilation.

But when I try to use the tsc-alias we move all the .d.ts to dist/src while the other files are on dist root.

But when I try to use the tsc-alias we move all the .d.ts to dist/src while the other files are on dist root.

This is usually due to tsconfig.json wrongly configured, to remove src folder level, we can configure like below:

{
  "compilerOptions": {
    "baseUrl": ".",
    "rootDir": "src",
  },
  "include": ["src"]
}

Open another issue and provide reproduction demo if you have further questions.
