#lib.outBase

• Type: string
• Default Value: undefined

When building a project where source files exist across multiple directories with bundleless mode, the output directory structure will be replicated relative to the outBase directory in the output directory. If no base output directory is specified, the lowest common ancestor of all input entry points is used by default.

Configuring outBase will change the path of the base output directory. outBase can be either a relative path from the current process directory or an absolute path.

For example, we have the following directory structure:

.
├── package.json
├── rslib.config.ts
└── src
    └── utils
        ├── bar
        │   └── index.ts
        ├── foo
        │   └── index.ts
        └── index.ts

If the output base directory is not specified, the lowest common ancestor of all input entry point paths, i.e. ./src/utils, is used by default, and the final file output structure is:

dist
├── bar
│   └── index.js
├── foo
│   └── index.js
└── index.js

When outBase is configured as ./src, the output directory structure is:

dist
└── utils
    ├── bar
    │   └── index.js
    ├── foo
    │   └── index.js
    └── index.js
