Any updates on this? |

i have the same problem..... |
|
Just tested this with the latest version (2.3.7) and can confirm this bug is still present |
|
Just using // vite.config.js
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import path from "path";
// https://vitejs.dev/config/
export default defineConfig({
build: {
lib: {
entry: path.resolve(__dirname, "src/main.js"),
name: "ViteUmdBug"
},
rollupOptions: {
external: ["vue"],
output: {
inlineDynamicImports: true, // <== here the entry
globals: {
vue: "Vue"
}
},
}
},
plugins: [vue()]
})output: yarn run v1.22.10

Thanks for the tip @userquin , that does indeed fix the immediate problem of being able to build. |
|
you can add 2 outputs, I will test it and feed back here... |
|
should output something like this? |
|
Right of course. We can't use code splitting with UMD builds as the error message clearly indicates. |

ok, you can use this configuration: // vite.config.js
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import path from "path";
// https://vitejs.dev/config/
export default defineConfig({
build: {
lib: {
entry: path.resolve(__dirname, "src/main.js"),
name: "ViteUmdBug"
},
rollupOptions: {
external: ["vue"],
output: [{
format: "esm",
esModule: true,
exports: "named",
globals: {
vue: "Vue"
}
}, {
format: "umd",
inlineDynamicImports: true,
interop: "esModule",
exports: "named",
globals: {
vue: "Vue"
}
}],
}
},
plugins: [vue()]
}) |

you can see it on my fork |
|
what do you want is to export // vite.config.js
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import path from "path";
// https://vitejs.dev/config/
export default defineConfig({
build: {
lib: {
entry: path.resolve(__dirname, "src/components/HelloWorld.vue"),
name: "HelloWorld"
},
rollupOptions: {
external: ["vue"],
output: [{
format: "es",
esModule: true,
exports: "named",
globals: {
vue: "Vue"
}
}, {
format: "umd",
inlineDynamicImports: true,
interop: "esModule",
exports: "named",
globals: {
vue: "Vue"
}
}],
}
},
plugins: [vue()]
}) |

I have the same problem, none of the above solutions/configs worked |

documentation
Describe the bug
When building a library (utilizing
build.lib), Vite tries to code-split the generated UMD (and presumably also IIFE) bundle, which fails with the message UMD and IIFE output formats are not supported for code-splitting builds.This is only a problem when building a library and when Vite detects points in the code that can be code-split (e.g. a dynamic
import).Reproduction
https://github.com/Robin-Hoodie/vite-umd-bug
This is a scaffolded Vite project using
vue.I updated
vite.config.jsto build in library mode based on the instructions in the documentationI also added a dynamic
importinsrc/App.vueto introduce code splittingI used
vite@2.0.0in the reproduction, but can confirm this is also an issue withvite@2.1.5System Info
