# Download example
Small example to show how to download a file in the browser with Codex.
## Install dependencies
```bash
npm install
```
## Build the javascript asset
```bash
CODEX_CID=REPLACE_BY_YOUR_CIDE npm run build
```
The response will be displayed as text, so it is better to test with .txt files.
Note: You can define `CODEX_NODE_URL`, default value is "http://localhost:8080".
## Check the results
Open the index.html and open the web console.
