tsconfigPath#

• Type: string
• Default: 'tsconfig.json'

Configure a custom tsconfig.json file path to use, can be a relative or absolute path.

Purpose#

The tsconfig.json configuration file affects the following behaviors of Rsbuild:

• The paths field is used to configure Path Aliases.
• Sets the scope and rules for the Type Check Plugin.

Example#

The value of source.tsconfigPath can be set to a relative or an absolute path. Relative path will be resolved relative to the project root directory.

• Relative path example:

export default {
  source: {
    tsconfigPath: './tsconfig.custom.json',
  },
};

• Absolute path example:

import path from 'node:path';

export default {
  source: {
    tsconfigPath: path.join(__dirname, 'tsconfig.custom.json'),
  },
};
