How does Atlas handle Electron's main and renderer processes during upgrades?

Atlas is designed to understand the distinct environments of Electron's main and renderer processes. When fixing code, it differentiates between `main.js` and renderer-specific files, applying fixes appropriate for each context. It pays particular attention to `preload.js` scripts and `contextBridge.exposeInMainWorld` calls, ensuring that security boundaries and `ipcRenderer.invoke` / `ipcMain.handle` communications remain correctly configured and functional after a dependency upgrade.

Can Atlas upgrade specific Electron dependencies like `electron-builder`?

Yes, Atlas can upgrade any dependency listed in your Electron project's `package.json`, including development dependencies like `electron-builder` or runtime dependencies. You specify the package name, and Atlas uses `npm` to perform the upgrade, then proceeds to fix any resulting compile or test failures across your codebase, just as it would for any other library.

What Electron testing frameworks does Atlas support for validation?

Atlas directly integrates with `@playwright/test`, the recommended testing framework for Electron applications, by executing `npm test` or equivalent commands via its `bash` tool. It parses the output to identify test failures and uses this feedback to guide its repair process. Atlas's approach is flexible enough to work with any testing framework that provides clear console output for test results.

How does Atlas ensure security when modifying Electron preload scripts?

Atlas is acutely aware of the security implications of Electron's `preload` scripts and `contextIsolation`. When modifying `preload.js`, Atlas prioritizes maintaining the integrity of `contextBridge.exposeInMainWorld` and ensuring that `nodeIntegration` remains off. All proposed changes to these sensitive areas are presented as unified diffs for your explicit review and approval, giving you the final say on security-critical modifications.

Does Atlas integrate with `prettier` for Electron code formatting?

Yes, Atlas integrates direct with `prettier` to ensure your Electron codebase remains consistently formatted after an upgrade. After all functional fixes are applied and tests pass, Atlas can execute `npm run format` (or your project's equivalent `prettier` command) via `atlas bash`. This step ensures that the code adheres to your project's style guidelines, preventing formatting-related merge conflicts and maintaining code readability.

How does Atlas manage `npm` package updates in Electron projects?

Atlas manages `npm` package updates by directly interacting with your project's `package.json` and `node_modules` via the `npm` command-line tool, executed through `atlas bash`. It can perform `npm install`, `npm update`, or `npm uninstall` operations. Atlas captures the full output of these commands, providing a transparent record of the package manager's actions and any warnings or errors encountered during the update process.

Can Atlas fix `ipcRenderer.invoke` and `ipcMain.handle` mismatches after an upgrade?

Absolutely. Atlas is designed to identify and fix mismatches in `ipcRenderer.invoke` calls in the renderer process and `ipcMain.handle` implementations in the main process. If an upgraded dependency changes the expected arguments or return types for these IPC channels, Atlas uses compiler output and `lsp` to pinpoint the discrepancies and propose corrective edits, ensuring your Electron application's inter-process communication remains robust.

Upgrade a Dependency and Fix Breakage in Electron with Atlas in 2026

Atlas empowers Electron developers in 2026 to confidently upgrade dependencies to new major versions and automatically repair all resulting compile and test failures. By directly interacting with your project's `package.json` via `npm`, reading real compiler output, and leveraging `@playwright/test` for validation, Atlas ensures your Electron application remains functional and secure. It understands the nuances of Electron's main and renderer processes, including `contextIsolation` and `preload` scripts, making it an indispensable tool for maintaining complex applications.

How does Atlas upgrade Electron dependencies?

Atlas initiates dependency upgrades in Electron projects by directly invoking `npm` through its `bash` tool, ensuring a familiar and robust process. In 2026, this approach guarantees that the upgrade adheres to your project's existing `package.json` configuration and `npm` ecosystem rules, handling version bumps and package resolution precisely as you would expect.

When you instruct Atlas to upgrade a dependency, it first drafts a plan in a read-only agent, outlining the `npm` command it will execute. For instance, to upgrade a package like `some-library` to its latest major version, Atlas will propose running `npm install some-library@latest` or `npm update some-library` within your Electron project's root directory. This command is then executed via the `atlas bash` tool, capturing the full output, which can be saved to a file if it exceeds typical terminal limits. This initial step ensures that the new version of the library is installed, and any immediate `npm` warnings or errors are logged, providing a clear starting point for subsequent fixes. Atlas's ability to read `git` branches and status also means it can stage and create commits on your behalf, isolating the upgrade to a dedicated branch for safe experimentation.

How does Atlas identify and fix Electron compile errors?

Atlas identifies compile errors in Electron applications by running your project's build or typecheck commands via `bash`, such as `npm run build` or `tsc`. This direct interaction with your Electron toolchain ensures that Atlas reads the actual compiler output, rather than making assumptions about breakage, allowing it to pinpoint issues with 100% accuracy.

After an `npm` upgrade, Atlas uses its `bash` tool to execute your Electron project's build or typechecking commands. For a TypeScript-based Electron app, this might involve `npm run build` or `tsc` directly, which then enumerates all compile-time errors. Atlas parses this output, understanding the file paths and line numbers of each error. It then uses its `edit` tool to navigate to the problematic code sections. For example, if a breaking change in a library affects how you interact with `ipcRenderer.invoke` in your renderer process or `ipcMain.handle` in your main process, Atlas can identify these specific call sites. Leveraging the `lsp` tool's `goToDefinition` operation, Atlas can inspect the new signatures of functions within the upgraded package, providing the necessary context to draft precise fixes that align with the library's updated API, ensuring your Electron security model with `contextIsolation` and `preload` bridges remains intact.

How does Atlas validate fixes with Electron's @playwright/test?

Atlas validates all code fixes in Electron projects by running your existing `@playwright/test` suite through its `bash` tool. This ensures that every repair not only compiles but also maintains the expected runtime behavior of your Electron application, providing a robust safety net for your 2026 development workflow.

Once Atlas has applied initial code fixes, it re-runs your Electron application's tests to confirm functionality. The standard testing framework for Electron applications, `@playwright/test`, is executed via `npm test` or a specific `npm run test` script, all managed by `atlas bash`. Atlas monitors the test output, identifying any failures that indicate remaining breakage or regressions. If a test fails, Atlas can then use its `edit` and `lsp` tools to investigate the test failure, much like it does with compile errors. This iterative process of fixing and re-testing continues until all tests pass, ensuring that the upgraded dependency does not introduce new bugs. Atlas can even write new `@playwright/test` cases that drive the packaged app, running behind a permission prompt, to cover specific edge cases introduced by the upgrade, further bolstering confidence in the stability of your Electron application.

What safety and review mechanisms does Atlas offer for Electron upgrades?

Atlas provides multiple layers of safety and review for Electron dependency upgrades, ensuring you maintain full control over every change. Before any file is written, Atlas computes a unified diff for every edit and surfaces it for your approval, preventing unintended modifications to your `main.js`, `preload.js`, or other critical Electron files in 2026.

Atlas prioritizes developer control and safety throughout the dependency upgrade process. Every Atlas tool call is permission-gated, allowing you to `allow`, `ask`, or `deny` its execution. Before Atlas writes any changes to your Electron codebase, it presents a unified diff for every modified file, such as `main.js`, `renderer.js`, `preload.js`, or `package.json`. You review these proposed changes and explicitly approve them before they are applied. Atlas also snapshots file changes as `git` patches, allowing edits to be easily diffed and rolled back if necessary. Furthermore, Atlas can read `git` branches, status, and diffs, and can stage and create commits on your behalf, ensuring that the entire upgrade process is version-controlled and auditable. After all fixes are applied and tests pass, Atlas can run `prettier` via `npm run format` to ensure code consistency, and then confirm that critical security settings like `nodeIntegration` remain off, adhering to best practices for Electron development.

Step by step

01Initiate the dependency upgrade in your Electron project by running `npm update <package-name>` or `npm install <package-name>@latest` using `atlas bash`.
02Fetch the library's release notes and changelog with `atlas webfetch` to understand the breaking changes before attempting fixes.
03Build or typecheck your Electron application by executing `npm run build` or `tsc` via `atlas bash` to enumerate all compile-time errors.
