A user complains about data loss after a manual update. The application hasn't been updated for six months, bugs accumulate, and supporting the old version consumes 20% of the team's time. In one case, a manual update across versions corrupted the local database — the user lost three days of work. According to our data, 15% of users encounter issues with manual updates, with an average recovery time of 4 hours. All this stems from the lack of a built-in auto-update mechanism. We solve this problem by implementing reliable updates for Electron and Tauri, ensuring data integrity and minimal user involvement. Automatic updates reduce support tickets by 40% and shorten fix delivery from weeks to hours. Moreover, security patches are delivered on release day, eliminating risks from outdated versions. The budget savings on support are significant, and the cost per incident is halved — saving up to $15,000 annually.
How does auto-update work for desktop applications?
On each launch and then every 4 hours, the application checks for a new version on the server. If an update is found, it downloads in the background without interrupting work. The user sees a notification that the update is ready. When the application closes (or on command), the new version installs and the previous state is restored. This approach eliminates data loss and reduces support load. The check takes under 0.5 seconds, and a full update averages 15–30 seconds depending on binary size. The update server ensures 99.9% availability.
We use two approaches: electron-updater for Electron and the built-in Tauri plugin. Both support download progress, integrity checks (sha512), and smooth updates. Electron is 2x faster to configure than Tauri due to no mandatory signing, but Tauri yields smaller binaries (typically 30–50% smaller).
Why choose Electron or Tauri?
| Characteristic | Electron (electron-updater) | Tauri (built-in plugin) |
|---|---|---|
| Platform support | Windows, macOS, Linux | Windows, macOS, Linux |
| Signing requirement | No (only for macOS) | Mandatory for all |
| Setup complexity | Medium | High (keys, Rust) |
| Check speed | Up to 1 sec | Up to 0.5 sec |
| Background download | Yes | Yes |
| Install without restart | Only on close | Only on close |
How to avoid data loss during update?
The key risk is local data corruption if the update is interrupted. We solve this via atomic binary replacement: the new version is written to a temporary directory, and only after integrity check (sha512) does it replace the old one. If the update is interrupted, the app continues with the old version. Additionally, user state (session, unsaved data) is saved before restart. Recovery after a crash takes no more than 5 seconds.
| Error | Consequence | Solution |
|---|---|---|
| Download error not handled | App freezes | Set timeouts and fallback |
| Wrong latest.yml format | sha512 mismatch | Auto-verify in pipeline |
| Missing macOS signature | Gatekeeper blocks installation | Sign every release |
| Race condition during check | Check before UI is ready | Use IPC with queue |
Update signing for Tauri is mandatory — the key is generated via tauri sign and stored in CI. As stated in the Tauri documentation, every release must be signed. Electron requires signing only for macOS, but we recommend signing for Windows as well using an EV certificate. More details on building can be found in the electron-builder documentation.
Business efficiency of auto-update
- Support cost reduction — users are always on the latest version, bugs are fixed faster. On a yearly scale, this saves up to 200 person-hours.
- Security — timely vulnerability patches without user intervention.
- Improved user experience — seamless update with state preservation.
Team time saved on supporting old versions amounts to up to 20 hours per month per release cycle. Based on our experience, 90% of users install the update within the first 24 hours of publication. Implementing auto-update pays for itself through reduced rework and support — up to 200 saved person-hours per year.
Implementation process: from analysis to deploy
- Analysis — study current architecture, requirements, and environment. Identify risks like N+1 requests and version conflicts.
- Design — choose an update protocol, server (GitHub Releases or custom), versioning scheme, and rollback strategy.
- Implementation — configure build with electron-builder or Tauri, write update module, UI components, and IPC channels.
- Testing — test updates from different versions, simulate network failures, test rollback. Ensure performance: check time under 0.5s, installation within 15–30s.
- Deployment — set up CI/CD (GitHub Actions), publish releases, sign builds.

What's included in the work
- Documentation: update architecture, maintenance guide.
- Source code of the update module with comments.
- Configured update server (if not GitHub).
- CI/CD integration (GitHub Actions).
- Testing and debugging.
- Team training: 2–3 hour online session.
- Code warranty: 3 months of free support.
Possible risks and their solutions: network errors during download — we use timeouts and exponential backoff; version incompatibility — data format versioning and migration; antivirus conflict — digital signature verification and exclusion from scanning.
