• relates to issue devDependencies review #164

Situation

[email protected] released on Jul 21, 2019 is configured in this repo. The latest version is [email protected], released one year ago in Sep 2024, and which uses outdated dependencies, such as [email protected] with end-of-life on Oct 5, 2024.

[email protected] released on Apr 5, 2018 is configured in this repo. The latest version is [email protected], released 5 years ago in Apr 2020, and which uses outdated dependencies, such as [email protected] with end-of-life on Nov 8, 2020, and multiple unfixable vulnerabilities:

15 vulnerabilities (4 low, 3 moderate, 6 high, 2 critical)

Assessment

The above two dependencies need to be considered together, since they are interdependent. They also each depend on different versions of ESlint.

• standard is a legacy ESlint-based linter with no configuration options
• prettier-standard is a formatter based on using prettier and standard. This repo has not defined any prettier configuration and it uses a non-standard set of configuration defaults.

Change

Remove standard and prettier-standard, and replace with supported npm packages:

• [email protected]
• [email protected]
• @stylistic/[email protected]
• [email protected]

For scripts:

• migrate script lint from standard to eslint
• remove scripts prelint and pretty

Apply npx eslint --fix, after setting rules as below, to autofix linting.

Rules

Apply a rule strategy based on each linter's recommended configuration:

• pluginJs.configs.recommended
• mochaPlugin.configs.recommended
• stylistic.configs.recommended

In case of linting errors, add rules aligned to linting choices in https://github.com/cypress-io/cypress

Rule	Setting	Cypress reference
mocha/max-top-level-suites	off	packages/eslint-config
mocha/no-mocha-arrows	off	packages/eslint-config
mocha/no-setup-in-describe	off	packages/eslint-config
@stylistic/arrow-parens	['error', 'always']	npm/eslint-plugin-dev
@stylistic/comma-dangle	['error', 'always-multiline']	packages/eslint-config
@stylistic/space-before-function-paren	['error', 'always']	packages/eslint-config

Verify

git clean -xfd
npm ci
npm run lint
npm test

Reference

• cypress-io > packages/eslint-config

with fallback to:

• cypress-io > npm/eslint-plugin-dev
