infisical-node

Open-source, end-to-end encrypted tool to manage secrets and configs across your team and infrastructure.

Deprecated!

This is now considered a legacy SDK, as we have released a new SDK that will be receiving all future updates. You can find it here.

Basic Usage

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", {
        environment: "dev",
        path: "/",
        type: "shared"
    });
    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.

It is also possible to use the SDK to encrypt/decrypt text; the implementation uses aes-256-gcm with components of the encryption/decryption encoded in base64.

import InfisicalClient from "infisical-node";
const client = new InfisicalClient();

// some plaintext you want to encrypt
const plaintext = "The quick brown fox jumps over the lazy dog";

// create a base64-encoded, 256-bit symmetric key
const key = client.createSymmetricKey();

// encrypt
const { ciphertext, iv, tag } = client.encryptSymmetric(plaintext, key);

// decrypt
const cleartext = client.decryptSymmetric(ciphertext, key, iv, tag);

Installation

$ npm install infisical-node

Configuration

Import the SDK and create a client instance with your Infisical Token.

const InfisicalClient = require("infisical-node");

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

Using ES6:

import InfisicalClient from "infisical-node";

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

// your app logic

Using Infisical Token V3 (Beta):

In v1.4.0, we released a superior token authentication method; this credential is a JSON containing a publicKey, privateKey, and serviceToken and can be used to initialize the Node SDK client instead of the regular service token.

You can use this beta feature like so:

const InfisicalClient = require("infisical-node");

const client = new InfisicalClient({
    tokenJson: "your_infisical_token_v3_json"
});

Options

Parameter	Type	Description
token	string	An Infisical Token scoped to a project and environment(s).
tokenJson	string	An Infisical Token V3 JSON scoped to a project and environment(s) - in beta
siteURL	string	Your self-hosted Infisical site URL. Default: https://app.infisical.com.
cacheTTL	number	Time-to-live (in seconds) for refreshing cached secrets. Default: 300.
debug	boolean	Turns debug mode on or off. Default: false.

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.

Secrets

Get Secrets

const secrets = await client.getAllSecrets({
    environment: "dev",
    path: "/foo/bar/",
    attachToProcessEnv: false,
    includeImports: false
});

Retrieve all secrets within a given environment and folder path. The service token used must have access to the given path and environment.

Parameters

• options (object)
  • environment The slug name (dev, prod, etc) of the environment from where secrets should be fetched from
  • path The path from where secrets should be fetched from
  • attachToProcessEnv (boolean, optional): Whether or not to attach fetched secrets to process.env. If not specified, the default value is false.
  • includeImports (boolean, optional): Whether or not to include imported secrets from the current path. Read about secret import.

Get Secret

Retrieve a secret from Infisical:

const secret = await client.getSecret("API_KEY", {
    environment: "dev",
    path: "/",
    type: "shared"
});
const value = secret.secretValue; // get its value

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.

To explicitly retrieve a shared secret:

const secret = await client.getSecret("API_KEY", {
    environment: "dev",
    path: "/",
    type: "shared"
});
const value = secret.secretValue; // get its value

Parameters

• secretName (string): The key of the secret to retrieve.
• options (object, optional): An options object to speify the type of secret.
  • environment The slug name (dev, prod, etc) of the environment from where secrets should be fetched from
  • path The path from where secrets should be fetched from
  • type (string, optional): The type of the secret. Valid options are "shared" or "personal". If not specified, the default value is "personal".

Create Secret

Create a new secret in Infisical:

const newApiKey = await client.createSecret("API_KEY", "FOO", {
    environment: "dev",
    path: "/",
    type: "shared"
});

Parameters

• secretName (string): The key of the secret to create.
• secretValue (string): The value of the secret.
• options (object, optional): An options object to specify the type of secret.
  • environment The slug name (dev, prod, etc) of the environment where secret should be created
  • path The path from where secret should be created.
  • type (string, optional): The type of the secret. Valid options are "shared" or "personal". If not specified, the default value is "shared". A personal secret can only be created if a shared secret with the same name exists.

Update Secret

Update an existing secret in Infisical:

const updatedApiKey = await client.updateSecret("API_KEY", "BAR", {
    environment: "dev",
    path: "/",
    type: "shared"
});

Parameters

• secretName (string): The key of the secret to update.
• secretValue (string): The new value of the secret.
• options (object, optional): An options object to specify the type of secret.
  • environment The slug name (dev, prod, etc) of the environment where secret should be updated.
  • path The path from where secret should be updated.
  • type (string, optional): The type of the secret. Valid options are "shared" or "personal". If not specified, the default value is "shared".

Delete Secret

Delete a secret in Infisical:

const deletedSecret = await client.deleteSecret("API_KEY", {
    environment: "dev",
    path: "/",
    type: "shared"
});

Parameters

• secretName (string): The key of the secret to delete.
• options (object, optional): An options object to specify the type of secret to delete.
  • environment The slug name (dev, prod, etc) of the environment where secret should be deleted.
  • path The path from where secret should be deleted.
  • type (string, optional): The type of the secret. Valid options are "shared" or "personal". If not specified, the default value is "shared". Note that deleting a shared secret also deletes all associated personal secrets.

Cryptography

Create Symmetric Key

Decrypt Symmetric

Decrypt ciphertext -> plaintext/cleartext.

const cleartext = client.decryptSymmetric(ciphertext, key, iv, tag);

Parameters

• ciphertext (string): The ciphertext to decrypt.
• key (string): The base64-encoded, 256-bit symmetric key to use to decrypt the ciphertext.

Contributing

Bug fixes, docs, and library improvements are always welcome. Please refer to our Contributing Guide for detailed information on how you can contribute.

Getting Started

If you want to familiarize yourself with the SDK, you can start by forking the repository and cloning it in your local development environment. The project requires Node.js to be installed on your machine.

After cloning the repository, install the depenencies by running the following command in the directory of your cloned repository:

$ npm install

To run existing tests, you need to make a .env at the root of this project containing a INFISICAL_TOKEN and SITE_URL. This will execute the tests against a project and environment scoped to the INFISICAL_TOKEN on a running instance of Infisical at the SITE_URL (this could be Infisical Cloud).

To run all the tests you can use the following command:

$ npm test
