Discussion on: Migrating and configuring Eslint with Angular 11

[Giovanni Sarciotto]

Fair enough, maybe eslint-angular is disabling these rules since I know that at least the semi one is enabled by @typescript-eslint/recommended, will check it out later. Glad you could figure it out tho!

[John Tsombakos]

As far as I can see, looking through the rules, semi is not enabled by @typescript-eslint/recommended

rules: {
        '@typescript-eslint/adjacent-overload-signatures': 'error',
        '@typescript-eslint/ban-ts-comment': 'error',
        '@typescript-eslint/ban-types': 'error',
        '@typescript-eslint/explicit-module-boundary-types': 'warn',
        'no-array-constructor': 'off',
        '@typescript-eslint/no-array-constructor': 'error',
        'no-empty-function': 'off',
        '@typescript-eslint/no-empty-function': 'error',
        '@typescript-eslint/no-empty-interface': 'error',
        '@typescript-eslint/no-explicit-any': 'warn',
        '@typescript-eslint/no-extra-non-null-assertion': 'error',
        'no-extra-semi': 'off',
        '@typescript-eslint/no-extra-semi': 'error',
        '@typescript-eslint/no-inferrable-types': 'error',
        '@typescript-eslint/no-misused-new': 'error',
        '@typescript-eslint/no-namespace': 'error',
        '@typescript-eslint/no-non-null-asserted-optional-chain': 'error',
        '@typescript-eslint/no-non-null-assertion': 'warn',
        '@typescript-eslint/no-this-alias': 'error',
        'no-unused-vars': 'off',
        '@typescript-eslint/no-unused-vars': 'warn',
        '@typescript-eslint/no-var-requires': 'error',
        '@typescript-eslint/prefer-as-const': 'error',
        '@typescript-eslint/prefer-namespace-keyword': 'error',
        '@typescript-eslint/triple-slash-reference': 'error',
    },

which extends:

           rules: {
                'constructor-super': 'off',
                'getter-return': 'off',
                'no-const-assign': 'off',
                'no-dupe-args': 'off',
                'no-dupe-class-members': 'off',
                'no-dupe-keys': 'off',
                'no-func-assign': 'off',
                'no-import-assign': 'off',
                'no-new-symbol': 'off',
                'no-obj-calls': 'off',
                'no-redeclare': 'off',
                'no-setter-return': 'off',
                'no-this-before-super': 'off',
                'no-undef': 'off',
                'no-unreachable': 'off',
                'no-unsafe-negation': 'off',
                'no-var': 'error',
                'prefer-const': 'error',
                'prefer-rest-params': 'error',
                'prefer-spread': 'error',
                'valid-typeof': 'off', // ts(2367)
            },

the no-extra-semi rule just warns if there is more than one semi-colon (;;)
