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.
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 By doing so, it eliminates reliance on outdated Electron building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.
- Use function abstractions (such as map, reduce, filter etc.) over
for-of loops to gain benefits of having less side effects and easier
readability.
- Enable `downLevelIterations` for writing modern code with lazy evaluation.
- Refactor for of loops to named abstractions to clearly express their
intentions without needing to analyse the loop itself.
- Add missing cases for changes that had no tests.
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).
TSLint deprecated and is being replaced by ESLint.
Add Vue CLI plugin (@vue/cli-plugin-eslint) using:
`vue add @vue/cli-plugin-eslint`. It also adds `.eslintrc.js` manually
for Cypress since Vue CLI for ESLint misses it (vuejs/vue-cli#6892).
Also rename `npm run lint:vue` to `npm run lint:eslint` for better
clarification.
This commit disables all rules that the current code is not compliant
with. This allows for enabling them gradually and separating commits
instead of mixing ESLint introduction with other code changes.
AirBnb is chosen as base configuration.
"Standard" is not chosen due to its poor defaults. It makes code cleaner
but harder to maintain:
- It converts interfaces to types which is harder to read.
- Removes semicolons that helps to eliminate some ambigious code.
"Airbnb" on the other hand helps for easier future changes and
maintinability:
- Includes more useful rules.
- Keeps the semicolons and interfaces.
- Enforces trailing commas that makes it easier to delete lines later on.
- Delete branches: standard, prettier.
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).
