# Inject secrets into a Gatsby app

> How to use Infisical to inject environment variables and secrets into a Gatsby app.

Prerequisites:

* Set up and add envars to [Infisical Cloud](https://app.infisical.com)
* [Install the CLI](https://infisical.com/docs/cli/install.md)

## Initialize Infisical for your [Gatsby](https://www.gatsbyjs.com) app

```bash theme={"dark"}
# navigate to the root of your of your project 
cd /path/to/project

# then initialize Infisical
infisical init
```

## Start your application as usual but with Infisical

```bash theme={"dark"}
infisical secrets-manager run -- <your application start command>

# Example
infisical secrets-manager run -- npm run develop
```

> [!NOTE]
>
> Note that for environment variables to be exposed to the client, you'll have
> to prefix them with `GATSBY_`. Read more about that
> [here](https://www.gatsbyjs.com/docs/how-to/local-development/environment-variables/#accessing-environment-variables-in-the-browser).
