TextDB

TextDB is a non-destructive, completely offline, local-first text editor. Its core promise is simple: your edits never overwrite your history. Every manual save is immutable and append-only, and autosaves are kept as a separate draft layer. No accounts, no telemetry, no remote fonts, and no network calls.

Features

Non-destructive editing: manual saves are immutable; drafts never overwrite manual versions.
Sidebar list of texts with live search (titles + version bodies).
Editor with title, content area, and clear save status.
Cmd/Ctrl+S creates a new immutable manual version.
Autosave draft (debounced) that can be safely discarded.
History panel listing versions by timestamp (drafts included when present).
Export the current text to a .txt file.
Open .txt files to create new entries from file content.
Drag and drop .txt files onto the window to import them.
Registers .txt file association for using TextDB as a default editor.

Use cases

Non-destructive notepad: jot ideas without fear of losing earlier thoughts.
Safe editor for authors: keep every revision and compare or roll back at any time.
Research notes: maintain evolving notes with an audit trail of changes.
Sensitive drafts: keep local-only writing with immutable history and zero cloud sync.
Prompt or snippet library: store and iterate on reusable text safely.

Install & run

Install dependencies:

npm install

Start the app:

npm run tauri dev

Autosave + versioning behavior

Typing triggers a debounced autosave (~600ms) that writes to the draft record.
Manual saves (Cmd/Ctrl+S or the button) append a new version and clear any draft.
Autosave only overwrites the single draft row; manual versions are never overwritten.
History shows all manual versions plus the current draft (if any).

Local storage

SQLite is loaded via Database.load("sqlite:text.db").
The database file is stored in the Tauri app data directory.
The app is fully offline by design: no telemetry, no external fonts, no CDNs.
