Infisical Node.js SDK

If you’re working with Node.js, the official Infisical Node SDK package is the easiest way to fetch and work with secrets for your application.

• NPM Package
• Github Repository

Basic Usage

import express from "express";

import { InfisicalClient } from "@infisical/sdk";

const app = express();

const PORT = 3000;

const client = new InfisicalClient({
    siteUrl: "https://app.infisical.com", // Optional, defaults to https://app.infisical.com
    auth: {
      universalAuth: {
        clientId: "YOUR_CLIENT_ID",
        clientSecret: "YOUR_CLIENT_SECRET"
      }
    }
});

app.get("/", async (req, res) => {
  // Access the secret
  
    const name = await client.getSecret({
        environment: "dev",
        projectId: "PROJECT_ID",
        path: "/",
        type: "shared",
        secretName: "NAME"
    });

    res.send(`Hello! My name is: ${name.secretValue}`);
});

app.listen(PORT, async () => {
    // initialize client

    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.

We do not recommend hardcoding your Machine Identity Tokens. Setting it as an environment variable would be best.

Installation

Run npm to add @infisical/sdk to your project.

$ npm install @infisical/sdk

Configuration

Import the SDK and create a client instance with your Machine Identity.

• ES6
• ES5

import { InfisicalClient, LogLevel } from "@infisical/sdk";

const client = new InfisicalClient({
    auth: {
      universalAuth: {
        clientId: "YOUR_CLIENT_ID",
        clientSecret: "YOUR_CLIENT_SECRET"
      }
    },
    logLevel: LogLevel.Error
});

auth

AuthenticationOptions

The authentication object to use for the client. This is required unless you’re using environment variables.

Authentication

The SDK supports a variety of authentication methods. The most common authentication method is Universal Auth, which uses a client ID and client secret to authenticate.

Universal Auth

Using environment variables

• INFISICAL_UNIVERSAL_AUTH_CLIENT_ID - Your machine identity client ID.
• INFISICAL_UNIVERSAL_AUTH_CLIENT_SECRET - Your machine identity client secret.

Using the SDK directly

const client = new InfisicalClient({
    auth: {
      universalAuth: {
        clientId: "YOUR_CLIENT_ID",
        clientSecret: "YOUR_CLIENT_SECRET"
      }
    }
});

GCP ID Token Auth

Please note that this authentication method will only work if you’re running your application on Google Cloud Platform. Please read more about this authentication method.

Using environment variables

• INFISICAL_GCP_AUTH_IDENTITY_ID - Your Infisical Machine Identity ID.

Using the SDK directly

const client = new InfisicalClient({
    auth: {
      gcpIdToken: {
        identityId: "YOUR_IDENTITY_ID"
      }
    }
});

GCP IAM Auth

Using environment variables

• INFISICAL_GCP_IAM_AUTH_IDENTITY_ID - Your Infisical Machine Identity ID.
• INFISICAL_GCP_IAM_SERVICE_ACCOUNT_KEY_FILE_PATH - The path to your GCP service account key file.

Using the SDK directly

const client = new InfisicalClient({
    auth: {
      gcpIam: {
        identityId: "YOUR_IDENTITY_ID",
        serviceAccountKeyFilePath: "./path/to/your/service-account-key.json"
      }
    }
});

AWS IAM Auth

Please note that this authentication method will only work if you’re running your application on AWS. Please read more about this authentication method.

Using environment variables

• INFISICAL_AWS_IAM_AUTH_IDENTITY_ID - Your Infisical Machine Identity ID.

Using the SDK directly

const client = new InfisicalClient({
    auth: {
      awsIam: {
        identityId: "YOUR_IDENTITY_ID"
      }
    }
});

Azure Auth

Please note that this authentication method will only work if you’re running your application on Azure. Please read more about this authentication method.

Using environment variables

• INFISICAL_AZURE_AUTH_IDENTITY_ID - Your Infisical Machine Identity ID.

Using the SDK directly

const client = new InfisicalClient({
  auth: {
    azure: {
      identityId: "YOUR_IDENTITY_ID"
    }
  }
});

Kubernetes Auth

Please note that this authentication method will only work if you’re running your application on Kubernetes. Please read more about this authentication method.

Using environment variables

• INFISICAL_KUBERNETES_IDENTITY_ID - Your Infisical Machine Identity ID.
• INFISICAL_KUBERNETES_SERVICE_ACCOUNT_TOKEN_PATH_ENV_NAME - The environment variable name that contains the path to the service account token. This is optional and will default to /var/run/secrets/kubernetes.io/serviceaccount/token.

Using the SDK directly

const client = new InfisicalClient({
  auth: {
    kubernetes: {
      identityId: "YOUR_IDENTITY_ID",
      serviceAccountTokenPathEnvName: "/var/run/secrets/kubernetes.io/serviceaccount/token" // Optional
    }
  }
});

Caching

To reduce the number of API requests, the SDK temporarily stores secrets it retrieves. By default, a secret remains cached for 5 minutes after it’s first fetched. Each time it’s fetched again, this 5-minute timer resets. You can adjust this caching duration by setting the “cacheTtl” option when creating the client.

Working with Secrets

    environment: "dev",
