What is your level of experience with Vault and how deeply do you integrate it into your projects?

Vault is a tool for secure storage and management of secrets such as tokens, passwords, certificates, and encryption keys. In my projects, I use Vault for centralized secret management, which helps improve security and simplifies key rotation.

The depth of implementation depends on the project requirements. Usually, I integrate Vault with CI/CD pipelines to automatically retrieve secrets during deployment, as well as configure dynamic secret creation (e.g., for databases) and access management through Vault policies.

Example of using Vault with Node.js:

const vault = require('node-vault')({ endpoint: 'http://127.0.0.1:8200', token: process.env.VAULT_TOKEN });

async function getSecret() {
  try {
    const secret = await vault.read('secret/data/myapp/config');
    console.log(secret.data.data);
  } catch (err) {
    console.error('Error reading secret:', err);
  }
}

getSecret();

Thus, Vault helps ensure the security and manageability of secrets in projects.
