## Documentation and guides

- [Overview](https://eazip.io/js/docs): Eazip turns browser files, blobs, and remote URLs into one ZIP download — in the browser by default, in Eazip Cloud when jobs get big.
- [Scale with Eazip](https://eazip.io/js/docs/scale-with-eazip): Keep the Eazip.js API and move URL-based ZIP jobs beyond browser limits when you need to.
- [Concepts](https://eazip.io/js/docs/concepts): Understand the shared models behind Local, Cloud, React, and framework-agnostic JavaScript integrations.
- [Inputs and sources](https://eazip.io/js/docs/concepts/inputs): Understand accepted file shapes, ZIP entry names, and how Local and Cloud fetch remote URLs.
- [Partial results and errors](https://eazip.io/js/docs/concepts/partial-results): Understand when Eazip keeps successful files, fails the whole job, or returns a recoverable error.
- [Sessions and resume](https://eazip.io/js/docs/concepts/resume): Understand which Cloud credentials to retain and how to reconnect to a job after a reload.
- [Multi-ZIP splitting](https://eazip.io/js/docs/concepts/splitting): Understand how maxZipSizeBytes divides large output into predictable ZIP parts.
- [ZIP jobs](https://eazip.io/js/docs/concepts/zip-job): Choose createZip or startZip and understand the lifecycle shared by Local and Cloud execution.
- [Choose Your Integration Path](https://eazip.io/js/docs/getting-started/choose-your-integration): Pick between browser-only ZIP creation, Cloud with a public key, a backend-created session, or the HTTP API, based on where your file URLs live.
- [How Eazip.js works](https://eazip.io/js/docs/getting-started/how-it-works): The two open-source packages, their browser-first job model, and the optional managed execution path.
- [JavaScript](https://eazip.io/js/docs/getting-started/javascript): Create, observe, and download ZIP jobs in any browser application with @eazip/core.
- [React](https://eazip.io/js/docs/getting-started/react): Add a ZIP download button and a drop-in progress tray to a React application with @eazip/react.
- [Present the Eazip tray](https://eazip.io/js/docs/react/eazip-tray): Place, theme, embed, and control the ready-made React download interface.
- [Build a headless React UI](https://eazip.io/js/docs/react/headless): Render Eazip task state inside your own component library without the ready-made tray.
- [Localization](https://eazip.io/js/docs/react/i18n): Use the built-in English or Japanese tray messages, or override the copy your product needs.
- [React patterns](https://eazip.io/js/docs/react): Choose the right React pattern for task state, the download tray, localization, and Cloud persistence.
- [Persist Cloud tasks](https://eazip.io/js/docs/react/persistence): Understand how React reconnects to Cloud jobs after reload and when restored tasks can retry.
- [Control tasks with useEazip()](https://eazip.io/js/docs/react/use-eazip): Start ZIP downloads, read the current React task, and share defaults without duplicating engine state.
- [@eazip/core](https://eazip.io/js/docs/reference/core): Reference for Core functions, ZIP options, jobs, results, errors, and package entry points.
- [Reference](https://eazip.io/js/docs/reference): Look up the public Core and React APIs, options, task fields, results, errors, and component props.
