This commit applies `strictNullChecks` to the entire codebase to improve
maintainability and type safety. Key changes include:
- Remove some explicit null-checks where unnecessary.
- Add necessary null-checks.
- Refactor static factory functions for a more functional approach.
- Improve some test names and contexts for better debugging.
- Add unit tests for any additional logic introduced.
- Refactor `createPositionFromRegexFullMatch` to its own function as the
logic is reused.
- Prefer `find` prefix on functions that may return `undefined` and
`get` prefix for those that always return a value.
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.
As part of transition to Vue 3.0 and Vite (#230), this commit
facilitates the shift towards building rest of the application using
Vite. By doing so, it eliminates reliance on outdated Electron building
system that offered limited control, blocking desktop builds (#233).
Changes include:
- Introduce Vite with Vue 2.0 plugin for test execution.
- Remove `mocha`, `chai` and other related dependencies.
- Adjust test to Vitest syntax.
- Revise and update `tests.md` to document the changes.
- Add `@modyfi/vite-plugin-yaml` plugin to be able to use yaml file
depended logic on test files, replacing previous webpack behavior.
- Fix failing tests that are revealed by Vitest due to unhandled errors
and lack of assertments.
- Remove the test that depends on Vue CLI populating `process.env`.
- Use `jsdom` for unit test environment, adding it to dependency to
`package.json` as project now depends on it and it was not specified
even though `package-lock.json` included it.
- Unify test data for nonexistence of an object/string and collection.
- Introduce more test through adding missing test data to existing tests.
- Improve logic for checking absence of values to match tests.
- Add missing tests for absent value validation.
- Update documentation to include shared test functionality.
Major refactoring using ESLint with rules from AirBnb and Vue.
Enable most of the ESLint rules and do necessary linting in the code.
Also add more information for rules that are disabled to describe what
they are and why they are disabled.
Allow logging (`console.log`) in test files, and in development mode
(e.g. when working with `npm run serve`), but disable it when
environment is production (as pre-configured by Vue). Also add flag
(`--mode production`) in `lint:eslint` command so production linting is
executed earlier in lifecycle.
Disable rules that requires a separate work. Such as ESLint rules that
are broken in TypeScript: no-useless-constructor (eslint/eslint#14118)
and no-shadow (eslint/eslint#13014).
Alias would remove unnecessary repetitions and less relative paths make changes easier when moving around files. This commit cleans also up some relative paths ('../../../') by using the alias and orders imports. It updates both path alias in tsconfig and module alias in Vue CLI's bundler (vuejs/vue-cli#2398).
