Apache Cordova本地存储是否存在容量限制？与普通浏览器的限制是否一致？

Great question—let’s break down how Cordova handles storage, especially since you’re working with large volumes of non-sensitive data.

WebView-Based Storage: The Basics #

Cordova apps run on each platform’s native WebView (e.g., WKWebView on iOS, Chrome-based WebView on Android), so storage limits here mirror what you’d see in a mobile browser, with some platform-specific nuance:

• localStorage/sessionStorage: These have strict, small limits—usually around 5MB per origin across most platforms. If you’re storing large data, this is not the right choice; you’ll hit the cap quickly.
• IndexedDB: This is the better Web-standard option for larger datasets. Modern WebViews don’t enforce hard, arbitrary limits here—instead, the constraint is the device’s available storage space. Some platforms might prompt the user if your app tries to store hundreds of MBs or more, but since your data is non-sensitive, that’s a minor hurdle.

Cordova Plugins for Unlimited (Well, Device-Limited) Storage #

If you need to store gigabytes of data, you’ll want to bypass the WebView entirely and use native storage plugins:

• Cordova File Plugin: This lets you write files directly to the device’s internal or external storage. The only limit here is the actual free space on the user’s device. It’s perfect for non-sensitive large files since you can store as much as the device can accommodate.
• Cordova SQLite Plugin: SQLite is a lightweight, native relational database. It has no hard size limits beyond the device’s storage, and it’s ideal if you need to query or structure your large dataset instead of just storing raw files.

Quick Recommendation #

• Use IndexedDB if you want a plugin-free, Web-standard approach and your data is in the hundreds of MB range.
• Go with the File Plugin or SQLite Plugin for truly large datasets (GBs)—they leverage native storage and have no arbitrary WebView-imposed limits.
