MindooDB and Haven product updates, engineering notes, and sample app articles.https://mindoodb.comhttps://mindoodb.com/blog/2026/05/25.05.2026123000KLETE2https://mindoodb.com/blog/2026/05/25.05.2026123000KLETE2Mindoo TeamEdit gains a Word/.docx editing mode alongside the existing collaborative Markdown editor. Two people can now open the same .docx file in two TeamEdit instances, type into the same paragraph, drop in images, reshape a table, accept tracked changes, leave threaded comments - and watch the merged result appear on both screens through MindooDB's Automerge sync, with only the actually changed spans on the wire. TeamEdit also handles multiple documents open at once - a Window menu lists every open Markdown brief and Word memo and lets you flip between them. Under the hood the document is mapped to Automerge's rich text format (formatting spans plus block markers) on top of the EigenPal docx-editor we picked after evaluating SyncFusion and Apryse - chosen for its Apache 2.0 license, OOXML round-trip fidelity, and ProseMirror foundation that lets us plug in MindooDB's collaborative storage cleanly.Mon, 25 May 2026 12:30:00 GMThttps://mindoodb.com/blog/2026/05/21.05.2026110000KLETG2https://mindoodb.com/blog/2026/05/21.05.2026110000KLETG2Four days after the initial release we are shipping a big round of updates to Mindoo TeamGrid, the open source collaborative spreadsheet for MindooDB Haven. The headline feature is Virtual View Sheets - pick any virtual view configured in Haven (including views that combine your private data with work data and with data from a partner company's tenant) and drop it into your workbook as a normal worksheet that Excel formulas, charts and XLSX export can read. Alongside it: a much larger formula engine with 280 Excel-compatible functions courtesy of fast-formula-parser, the four chart types Excel users actually use day to day (Column, Bar, Line, Pie), spreadsheet templates with File / New from template..., hidden rows and columns that survive an Excel round trip, automatic cell type detection from typed content, and a selection and keyboard model much closer to what people expect from Excel. And all of it still merges across two laptops, two devices, and four tabs the same way it did on day one.Thu, 21 May 2026 11:00:00 GMThttps://mindoodb.com/blog/2026/05/19.05.2026195000KLEATChttps://mindoodb.com/blog/2026/05/19.05.2026195000KLEATCAttachments in MindooDB are not stored as one blob hanging off a document. Each file is a chain of small encrypted chunks (256 KB by default, encrypted with the document's own key), and each chunk points back at its predecessor. The document only references the *last* chunk - which turns growing a file into appending one chunk, makes earlier document revisions automatically see only the bytes that existed then, and reduces moving or duplicating a large attachment between documents to copying a tiny JSON entry. Chunks are deduplicated by a hash of their encrypted bytes, so the same file inside one MindooDB database occupies storage once and syncs once. On top of all that, Haven streams long media attachments straight from those decrypted chunks - and for older MP4 files that browsers refuse to stream, Haven rebuilds them on the fly into a streamable shape with a lazy-loaded mp4box.js pipeline.Tue, 19 May 2026 17:50:00 GMThttps://mindoodb.com/blog/2026/05/18.05.2026133000KLESCNhttps://mindoodb.com/blog/2026/05/18.05.2026133000KLESCNHold a phone over a piece of paper, press one button, and it lands inside the document you are working on - cropped, deskewed, rotated, and saved as a clean PDF or image. The new Scan document feature in MindooDB Haven is built on a custom, size-optimized OpenCV WebAssembly build that finds the page corners automatically and lets you nudge them by hand. Pick A4, Letter, a square or just keep the original aspect ratio, rotate in 90-degree steps, then Add to document - where it becomes a regular MindooDoc attachment - or, on iOS, iPadOS and desktop Safari, press Share file to hand the scan straight to the system Share Sheet without any upload at all. Available out of the box to every MindooDB app via the MindooDB App SDK.Mon, 18 May 2026 13:30:00 GMThttps://mindoodb.com/blog/2026/05/17.05.2026175100KLEATThttps://mindoodb.com/blog/2026/05/17.05.2026175100KLEATTMindooDB Haven application registrations now carry an optional time travel date. Set it, launch the app, and every mapped database, every virtual view, every document and every attachment is served as it would have looked at that exact moment - read-only, all the way down to the historical attachment bytes. Duplicate the registration, pin two copies to two different dates, switch the runtime mode to 'Open in new window', and compare last sprint's plan against today's plan in two browser windows side by side. Audit, retrospective, regression debugging, and historical reporting - rendered in the real application UI, backed by MindooDB's signed, blockchain-style change history. Available out of the box for every MindooDB app running in Haven.Sun, 17 May 2026 15:51:00 GMThttps://mindoodb.com/blog/2026/05/17.05.2026153000KLETGRhttps://mindoodb.com/blog/2026/05/17.05.2026153000KLETGRMindoo TeamGrid is a new open source sample app for MindooDB Haven that demonstrates how a spreadsheet workbook can be collaboratively edited across devices, with stable IDs that keep formulas valid through concurrent row and column changes, Excel import and export via file and clipboard, and a new granular JSON patch API in the MindooDB App SDK.Sun, 17 May 2026 13:30:00 GMThttps://mindoodb.com/blog/2026/04/29.04.2026231300KLETEDhttps://mindoodb.com/blog/2026/04/29.04.2026231300KLETEDMindoo TeamEdit is a new sample app for MindooDB Haven that demonstrates collaborative markdown editing built on the new text edit API in the MindooDB App SDK, alongside custom document IDs, undelete, and historical attachment access.Wed, 29 Apr 2026 22:13:00 GMThttps://mindoodb.com/blog/2026/04/26.04.2026221000KLECFShttps://mindoodb.com/blog/2026/04/26.04.2026221000KLECFSHaven brings notes, files, apps, and data into one offline-ready team workspace, built on MindooDB so collaboration stays encrypted and under your control.Sun, 26 Apr 2026 21:10:00 GMT
