# Spack Builtin Shim
An attempt to use shims for node builtin modules.
```
yarn install
npx spack
```
When compiling with `spack` for the browser and using builtin modules such as `assert` and `events` we encountered this error when executing the generated bundle:
```
Uncaught SyntaxError: Cannot use import statement outside a module
```
It appears that builtin modules are passed through as `import` statements untouched as there is no available code to compile.
However, when we added the `assert` and `events` packages to be used as shims and updated `.swcrc` to configure the `paths`:
```json
{
"jsc": {
"paths": {
"assert": ["node_modules/assert"],
"events": ["node_modules/events"]
}
}
}
```
These shims for the builtin modules are not used and the compiled bundle still includes the original import statements.
