The configuration of sourceMap is complex and not simple enough

[zhangfisher]

吐槽一下，配置生成sourceMap的配置如下：

import { defineConfig } from '@rslib/core';

export default defineConfig({    
    output:{
        sourceMap: {
             js: "source-map",
        },
    },
    lib: [
        {
          format: 'esm',         
          output: {         
            distPath: {
              root: './dist/',
            }
          },
        },
        {
          format: 'cjs',
          output: {
            distPath: {
              root: './dist/',
            },
          },
        },
    ],
});

为什么不能是:

import { defineConfig } from '@rslib/core';

export default defineConfig({     
    lib: [
        {
          format: 'esm',      
         clear:true,
         sourceMap:true,   
          output: {         
            distPath: {
              root: './dist/',
            }
          },
        },
        {
          format: 'cjs',
          output: {
            distPath: {
              root: './dist/',
            },
          },
        },
    ],
});

文档本身就不清楚，应该提供 sourceMap:true 这样的配置作为最佳实践。
之所以提供rslib就是要简化，这点tsup的配置就比较值得配置。

相较而言rslib的配置比较不直观

The configuration of tsup looks flatter than that of Rslib. This is because Rslib chooses to inherit the Rsbuild configuration, which allows Rslib to provide richer and more fine-grained options than tsup.

And we will simplify the source map config in the next release, see web-infra-dev/rsbuild#4037.

Example:

lib: [
  {
    format: 'esm',
    output: {
      sourceMap: true,
      distPath: {
        root: './dist/',
      },
    },
  },
];
