After upgrading to 1.10.0, the use of top await in pdfjs-dist v4+ caused compilation errors on my end. I tried downgrading to 1.9.7, which resolved the issue. Then, I used the @tato30/vue-pdf@1.10.0 + vite-plugin-top-level-await plugin to fix the error.

I submitted this issue in order to alert other users about how to resolve this problem.

vite 配置 optimizeDeps: { esbuildOptions: { target: 'esnext', }, },

try this

optimizeDeps: {
        include: ['pdfjs-dist'], // optionally specify dependency name
        esbuildOptions: {
            supported: {
                'top-level-await': true,
            },
        },
    },

This method works during development, but yarn build still throws an error. Currently, we are still using the vite-plugin-top-level-await plugin to resolve this issue.

@lhiro Thanks~

Try this, it's not recommend to change the build target, we just add top-level-await to support list

optimizeDeps: {
  esbuildOptions: {
    supported: {
      'top-level-await': true,
    },
  },
},
esbuild: {
  supported: {
    'top-level-await': true,
  },
},

🎉 @lhiro Thank you. After removing the vite-plugin-top-level-await plugin, I am now also able to run and build successfully.
