Installation

Add Vaultlier to your project. One package ships both the CLI and the runtime SDK.

Requirements

Node.js 18 or newer for the CLI (it uses nativefetch and Web Crypto).
The runtime SDK is edge-safe and additionally runs on Bun, Deno, Cloudflare Workers, Vercel Edge, and AWS Lambda.

Install the package

Vaultlier is distributed as a single npm package. Install it as a dependency so the runtime SDK is available at deploy time, and use the bundled CLI via npx or your package scripts.

Terminal

npm install vaultlier
# pnpm add vaultlier
# yarn add vaultlier
# bun add vaultlier

Running vaultlier initwill offer to install the dependency for you if it isn't present yet, detecting your package manager from the lockfile.

Entry points

The package exposes two import surfaces:

Import	Surface	Environment
`vaultlier`	Runtime SDK (createClient)	Edge-safe — Node 18+, Bun, Deno, Workers, Edge, Lambda
`vaultlier/cli`	CLI programmatic API	Node-only

The runtime entry uses only fetch and Web Crypto — no Node-only imports and no third-party dependencies.

Self-hosted portals

By default the CLI and SDK talk to the hosted portal at https://api.vaultlier.com. Point them at a self-hosted deployment with the --api-url flag or the VAULTLIER_API_URL environment variable.

Terminal

export VAULTLIER_API_URL=https://vault.internal.example.com
vaultlier pull --env=prod

See the CLI reference for the full flag list and the SDK reference for the baseUrl client option.
