When using the bundles imported via ``, you need to use the respective **namespace** to get access to the any of the functions within a module.
:::CodeblockTabs
index.html
```html
```
main.js
```javascript
(async () => {
// the 'namespace' of @signum/core is sig$
const ledger = sig$.LedgerClientFactory.create({
nodeHost: 'https://europe.signum.network',
});
const account = await ledger.account.getAccount({accountId: '16107620026796983538'});
console.log('Account', account);
})();
```

The modules are bundled using [IIFE](https://developer.mozilla.org/en-US/docs/Glossary/IIFE) [II](#), to avoid global naming collisions with your application. Keep also in mind that the bundles do not contain any type information, so your IDE cannot help you with auto-completion. If ever possible try to use a package manager to be more productive and even reduce the applications payload, as modern toolchains extract the used code from a package (tree shaking, dead code elimination).
:::
Each module of SignumJS comes with its own **namespace**
- **core - **`sig$`
- **util** - `sig$util`
- **contracts** - `sig$contracts`
- **wallets** - `sig$wallets`
- **crypto** -`sig$crypto`
- **http** - `sig$http`
