This commit upgrades TypeScript to the latest version 5.3 and introduces
`verbatimModuleSyntax` in line with the official Vue guide
recommendatinos (vuejs/docs#2592).
By enforcing `import type` for type-only imports, this commit improves
code clarity and supports tooling optimization, ensuring imports are
only bundled when necessary for runtime.
Changes:
- Bump TypeScript to 5.3.3 across the project.
- Adjust import statements to utilize `import type` where applicable,
promoting cleaner and more efficient code.
Enable `contextIsolation` in Electron to securely expose a limited set
of Node.js APIs to the renderer process. It:
1. Isolates renderer and main process contexts. It ensures that the
powerful main process functions aren't directly accessible from
renderer process(es), adding a security boundary.
2. Mitigates remote exploitation risks. By isolating contexts, potential
malicious code injections in the renderer can't directly reach and
compromise the main process.
3. Reduces attack surface.
4. Protect against prototype pollution: It prevents tampering of
JavaScript object prototypes in one context from affecting another
context, improving app reliability and security.
Supporting changes include:
- Extract environment and system operations classes to the infrastructure
layer. This removes node dependencies from core domain and application
code.
- Introduce `ISystemOperations` to encapsulate OS interactions. Use it
from `CodeRunner` to isolate node API usage.
- Add a preloader script to inject validated environment variables into
renderer context. This keeps Electron integration details
encapsulated.
- Add new sanity check to fail fast on issues with preloader injected
variables.
- Improve test coverage of runtime sanity checks and environment
components. Move validation logic into separate classes for Single
Responsibility.
- Improve absent value test case generation.
