## Zip File Compress & Download Pro **Zip File Compress & Download Pro** is a cutting‑edge plugin built exclusively for Bubble. It lets you create ZIP archives and deliver them to end‑users without writing a single line of code. The plugin handles compression, progress reporting, optional encryption, and flexible download options, so you can focus on the user experience instead of the mechanics of file archiving. --- ## 📦 Key Features | Feature | Description | | ------- | ----------- | | **One‑action Zip Generation** | A single workflow action compresses any set of files (images, PDFs, text files, etc.) into a ZIP archive. No multi‑step scripting required. | | **Real‑time Progress Updates** | While the archive is being built, the plugin emits progress events (percentage and status) that you can display to users in a progress bar or toast. | | **Secure Encryption (optional)** | When a password is supplied, the resulting ZIP is AES‑encrypted, protecting its contents from unauthorized access. | | **Multiple Download Options** | After the ZIP is ready you can:

Trigger a direct browser download.
Obtain a temporary public URL to share.
Save the file to a cloud storage service (e.g., Amazon S3, Google Cloud Storage) via a subsequent workflow step.

| | **Intuitive Integration** | Drag‑and‑drop the “Zip Generator” element onto any page, configure a few fields, and start using the actions immediately—no custom code needed. | | **Comprehensive Documentation & Support** | Detailed reference tables, step‑by‑step tutorials, and responsive support are included to help you get the most out of the plugin. | | **Regular Updates & Enhancements** | The development team releases frequent updates that add stability improvements, performance tweaks, and compatibility fixes. | > **Take your Bubble app to new heights with Zip File Compress & Download Pro.** Empower your users to create and download ZIP files effortlessly, streamlining their file‑management tasks while keeping the experience fully no‑code. --- ## 🔧 Installation 1. Open your Bubble editor. 2. Go to the **Plugins** tab → **Add plugins**. 3. Search for **“Zip File Compress & Download Pro”** and click **Install**. 4. The plugin will appear under **Installed plugins**. No additional licensing steps are required for the free tier; premium plans unlock higher file‑size limits and advanced cloud‑storage integration. --- ## ⚙️ Configuration After installation, a **Zip Generator** element is added to your visual element palette. | Setting | Type | Required? | Description | | ------- | ---- | --------- | ----------- | | **Zip File Name** | Text | Yes | The name of the generated archive (e.g., `my_documents.zip`). | | **Password (optional)** | Text | No | If supplied, the ZIP will be AES‑encrypted with this password. | | **Maximum File Size** | Number (MB) | No | Upper bound for the total size of files to be zipped in a single run. Exceeds this limit → “File size limit exceeded” error. | | **Include Sub‑folders** | Yes / No | No (default = Yes) | When you pass a list of folders, determines whether files inside nested folders are added. | | **Temporary URL Expiration** | Number (minutes) | No (default = 15) | How long the public download link remains valid. | | **Progress Update Interval** | Number (ms) | No (default = 500) | Frequency at which progress events are emitted. Lower values give smoother UI updates at the cost of more workflow calls. | > **Tip:** Keep the password field empty if you do not need encryption; this avoids the extra CPU overhead of encrypting the archive. --- ## 🚀 Usage ### 1. Add the Zip Generator element - Drag **Zip Generator** from the visual element palette onto the page where you want the ZIP creation UI to live. - Set the **Zip File Name** and (optionally) **Password** in the element’s property inspector. ### 2. Prepare a list of files Create a list of **File** objects (Bubble’s native file type). Typical sources: - Files uploaded via an **Upload file** input. - Files stored in a database field (type = file). - URLs fetched from an external API (must be converted to Bubble **File** using the “Download file from URL” action first). ### 3. Create a workflow to generate the ZIP | Step | Action | Parameters | | ---- | ------ | ---------- | | **1** | **Element Actions → Zip Generator → Generate Zip** | • **Files to zip** – the list of File objects.
• **Callback URL** – (optional) a backend endpoint to be called when the ZIP is ready. | | **2** (optional) | **Element Actions → Zip Generator → On Progress Updated** | Use the event to set a custom state (e.g., `progress_percent`) and display a progress bar. | | **3** | **Element Actions → Zip Generator → On Zip Ready** | • **Download URL** – temporary link to the ZIP file.
• **File Object** – the generated ZIP as a Bubble File (can be saved to the database). | | **4** (optional) | **Data → Create a new thing** | Store the ZIP file in your database for later retrieval or audit. | | **5** | **Navigation → Open external website** | Use the **Download URL** to trigger a direct browser download (or open in a new tab). | ### 4. Example: Showing a progress bar ```markdown 🟢 **State**: Page → `zipProgress` (number, default = 0) 📋 **Workflow** 1. When button “Create ZIP” is clicked → Run **Generate Zip**. 2. Event **On Progress Updated** → Set state `zipProgress` to `Progress %`. 3. Event **On Zip Ready** → Set state `zipProgress` to 100 and display a “Download” button that uses the returned URL. ``` --- ## 📚 API Reference ### Actions | Action | Description | Required Inputs | Output | | ------ | ----------- | --------------- | ------ | | **Generate Zip** | Starts the compression of the supplied file list. | • `Files to zip` (list of File)
• `Password` (optional) | None (triggers progress & ready events) | | **Cancel Generation** | Aborts an ongoing compression job. | – | – | | **Get Last Generated Zip** | Retrieves the most recent ZIP file object and URL (useful for re‑using a ZIP without regenerating). | – | `File` (ZIP), `Download URL` | ### Events | Event | Payload | Typical Use | | ----- | ------- | ----------- | | **On Progress Updated** | `percentage` (0‑100), `statusMessage` (string) | Update UI progress bars, show toast notifications. | | **On Zip Ready** | `zipFile` (Bubble File), `downloadUrl` (string) | Store the ZIP, present a download link, or push to cloud storage. | | **On Error** | `errorCode` (string), `errorMessage` (string) | Display user‑friendly error alerts, log for debugging. | --- ## 🛠️ Troubleshooting | Symptom | Likely Cause | Fix | | ------- | ------------ | --- | | **“File size limit exceeded”** | Total size of files > **Maximum File Size** setting or Bubble’s 2 GB per file cap. | Reduce the number/size of files, increase the limit in the plugin settings (if on a paid plan), or split the operation into multiple ZIPs. | | **Progress bar never reaches 100 %** | The workflow is timing out (default 60 s) before compression finishes. | Increase the **Workflow timeout** in Settings → API → “Maximum workflow duration”, or enable the **Progress Update Interval** to a larger value to reduce calls. | | **Downloaded ZIP cannot be opened (corrupt)** | One or more source files are corrupted or not fully loaded before compression starts. | Ensure all source files are fully uploaded/available (use “File is ready?” check) before calling **Generate Zip**. | | **Encrypted ZIP prompts “invalid password”** | Password contains unsupported characters or is mismatched between generation and extraction. | Use only ASCII characters (A‑Z, a‑z, 0‑9) for passwords, and keep the same password when extracting. | | **Download URL returns 404** | The temporary URL has expired. | Increase **Temporary URL Expiration** or generate a fresh ZIP before the user clicks the link. | --- ## 📞 Support & Updates - **Documentation Portal** – All reference tables, tutorials, and sample workflows are available at the plugin’s **Docs** tab. - **Community Forum** – Post questions in the “Zip File Compress & Download Pro” section of the Bubble forum; the development team monitors it daily. - **Email Support** – For urgent issues, email support@zipcompresspro.com.
