Installation

npm install zet-lib

Safe installation

zet-lib includes some optional heavy features, such as browser/PDF automation and image processing. If your app only needs the core helpers (database, cache, utilities, routers, mail, etc), a normal install is enough:

npm install zet-lib

If you want to avoid browser downloads in CI/CD or server environments:

PUPPETEER_SKIP_DOWNLOAD=1 npm install zet-lib

Optional features

• puppeteer

  • Used for browser/PDF style features.

  • Starting from zet-lib@6, it is treated as optional during install.

  • If you use a feature that needs Puppeteer and it is not installed, zet-lib will throw a clear error message.

  • To install it explicitly:

    npm install puppeteer

• sharp

  • Used for image processing/compression features.

  • It is optional because some environments do not need it or may have native install constraints.

  • To install it explicitly:

    npm install --include=optional sharp

Performance note

zet-lib lazily loads its exports. This means require("zet-lib") will not immediately load all heavy modules. Only the feature you access will load its underlying dependency tree.

Examples

Use only core utilities:

const { Util, connection } = require("zet-lib");

Use Puppeteer-powered features:

const { puppeteer } = require("zet-lib");

// Make sure puppeteer is installed in your project first.
