If you're working with Node.js, the official [infisical-node](https://github.com/Infisical/infisical-node) package is the easiest way to fetch and work with secrets for your application.

## Basic Usage

```js
import express from "express";
import InfisicalClient from "infisical-node";
const app = express();
const PORT = 3000;

const client = new InfisicalClient({
  token: "YOUR_INFISICAL_TOKEN"
});

app.get("/", async (req, res) => {
  // access value
  const name = await client.getSecret("NAME");
  res.send(`Hello! My name is: ${name.secretValue}`);
});

app.listen(PORT, async () => {
  console.log(`App listening on port ${PORT}`);
});
```

This example demonstrates how to use the Infisical Node SDK with an Express application. The application retrieves a secret named "NAME" and responds to requests with a greeting that includes the secret value.

<Warning>
  We do not recommend hardcoding your [Infisical
  Token](/documentation/platform/token). Setting it as an environment
  variable would be best.
</Warning>

## Installation

Run `npm` to add `infisical-node` to your project.

```console
$ npm install infisical-node --save
```

## Configuration

Import the SDK and create a client instance with your [Infisical Token](/documentation/platform/token).

  <Tab title="ES6">
    ```js
    import InfisicalClient from "infisical-node";
    
    const client = new InfisicalClient({
      token: "your_infisical_token"
    });
    ```

  </Tab>
  <Tab title="ES5">
    ```js
    const InfisicalClient = require("infisical-node");
    
    const client = new InfisicalClient({
      token: "your_infisical_token"
    });
    ````
  </Tab>

### Parameters

<ParamField query="options" type="object">
  <Expandable title="properties">
    <ParamField query="token" type="string" optional>
      An [Infisical Token](/documentation/platform/token) scoped to a project
      and environment
    </ParamField>
    <ParamField
      query="siteURL"
      type="string"
      default="https://app.infisical.com"
      optional
    >
      Your self-hosted absolute site URL including the protocol (e.g.
      `https://app.infisical.com`)
    </ParamField>
    <ParamField query="cacheTTL" type="number" default="300" optional>
      Time-to-live (in seconds) for refreshing cached secrets. Default: `300`.
    </ParamField>
    <ParamField query="debug" type="boolean" default="false" optional>
      Whether or not debug mode is on
    </ParamField>
  </Expandable>
</ParamField>

## Caching

The SDK caches every secret and updates it periodically based on the provided `cacheTTL`. For example, if `cacheTTL` of `300` is provided, then a secret will be refetched 5 minutes after the first fetch; if the fetch fails, the cached secret is returned.

<Tip>
  For optimal performance, we recommend creating a single instance of the Infisical client and exporting it to be used across your entire app to take advantage of caching benefits.
</Tip>

## Working with Secrets

### client.getAllSecrets()

```js
const secrets = await client.getAllSecrets();
```

Retrieve all secrets within the Infisical project and environment that client is connected to

### client.getSecret(secretName, options)

```js
const secret = await client.getSecret("API_KEY");
const value = secret.secretValue; // get its value
```

Retrieve a secret from Infisical.

By default, `getSecret()` fetches and returns a personal secret. If not found, it returns a shared secret, or tries to retrieve the value from `process.env`. If a secret is fetched, `getSecret()` caches it to reduce excessive calls and re-fetches periodically based on the `cacheTTL` option (default is `300` seconds) when initializing the client — for more information, see the caching section.

### Parameters

<ParamField query="secretName" type="string" required>
  The key of the secret to retrieve
</ParamField>
<ParamField query="options" type="object" optional>
  <Expandable title="properties">
    <ParamField query="type" type="string" default="personal" optional>
      The type of the secret. Valid options are "shared" or "personal"
    </ParamField>
  </Expandable>
</ParamField>

### client.createSecret(secretName, secretValue, options)

```js
const newApiKey = await client.createSecret("API_KEY", "FOO");
```

Create a new secret in Infisical.

<ParamField query="secretName" type="string" required>
  The key of the secret to create
</ParamField>
<ParamField query="secretName" type="string" required>
  The value of the secret to create
</ParamField>
<ParamField query="options" type="object" default="object" optional>
  <Expandable title="properties">
    <ParamField query="type" type="string" default="shared" optional>
      The type of the secret. Valid options are "shared" or "personal". A personal secret can only be created if a shared secret with the same name exists.
    </ParamField>
  </Expandable>
</ParamField>

### client.updateSecret(secretName, secretValue, options)

```js
const updatedApiKey = await client.updateSecret("API_KEY", "BAR");
```

Update an existing secret in Infisical.

### Parameters

<ParamField query="secretName" type="string" required>
  The key of the secret to update
</ParamField>
<ParamField query="secretName" type="string" required>
  The new value of the secret
</ParamField>
<ParamField query="options" type="object" default="object" optional>
  <Expandable title="properties">

      The type of the secret. Valid options are "shared" or "personal"
    </ParamField>
  </Expandable>
</ParamField>

### client.deleteSecret(secretName, options)

```js
const deletedSecret = await client.deleteSecret("API_KEY");
```

Delete a secret in Infisical.

<ParamField query="secretName" type="string" required>
  The key of the secret to delete
</ParamField>
<ParamField query="options" type="object" default="object" optional>
