Missing semicolon
Open

      this.#cache = new ObserverCache((entries) => this.onIntersectionEvent(entries));

Rule: semicolon

Enforces consistent semicolon usage at the end of every statement.

Notes
  • Has Fix

Config

One of the following arguments must be provided:

  • "always" enforces semicolons at the end of every statement.
  • "never" disallows semicolons at the end of every statement except for when they are necessary.

The following arguments may be optionally provided:

  • "ignore-interfaces" skips checking semicolons at the end of interface members.
  • "ignore-bound-class-methods" skips checking semicolons at the end of bound class methods.
  • "strict-bound-class-methods" disables any special handling of bound class methods and treats them as any other assignment. This option overrides "ignore-bound-class-methods".
Examples
"semicolon": true,always
"semicolon": true,never
"semicolon": true,always,ignore-interfaces
"semicolon": true,always,ignore-bound-class-methods
Schema

  "type": "array",

missing whitespace
Open

    options ??= {};

Rule: whitespace

Enforces whitespace style conventions.

Rationale

Helps maintain a readable, consistent style in your codebase.

Notes
  • Has Fix

Config

Several arguments may be optionally provided:

  • "check-branch" checks branching statements (if/else/for/while) are followed by whitespace.
  • "check-decl"checks that variable declarations have whitespace around the equals token.
  • "check-operator" checks for whitespace around operator tokens.
  • "check-module" checks for whitespace in import & export statements.
  • "check-separator" checks for whitespace after separator tokens (,/;).
  • "check-rest-spread" checks that there is no whitespace after rest/spread operator (...).
  • "check-type" checks for whitespace before a variable type specification.
  • "check-typecast" checks for whitespace between a typecast and its target.
  • "check-type-operator" checks for whitespace between type operators | and &.
  • "check-preblock" checks for whitespace before the opening brace of a block.
  • "check-postbrace" checks for whitespace after an opening brace.

unused expression, expected an assignment or function call
Open

    this.#nodes.size ? this.#observer.unobserve(node) : this.#destroy();

Rule: no-unused-expression

Disallows unused expression statements.

Unused expressions are expression statements which are not assignments or function calls (and thus usually no-ops).

Rationale

Detects potential errors where an assignment or function call was intended.

Config

Three arguments may be optionally provided:

  • allow-fast-null-checks allows to use logical operators to perform fast null checks and perform method or function calls for side effects (e.g. e && e.preventDefault()).
  • allow-new allows 'new' expressions for side effects (e.g. new ModifyGlobalState();.
  • allow-tagged-template allows tagged templates for side effects (e.g. this.add\foo`;`.
Examples
"no-unused-expression": true
"no-unused-expression": true,allow-fast-null-checks
Schema
{
  "type": "array",
  "items": {
    "type": "string",
    "enum": [

      "allow-new",
      "allow-tagged-template"
    ]
  },
  "minLength": 0,

Forbidden bitwise operation
Open

type Value = `${Positive | Negative}${Unit}`;

Rule: no-bitwise

Disallows bitwise operators.

Specifically, the following bitwise operators are banned: &, &=, |, |=, ^, ^=, <<, <<=, >>, >>=, >>>, >>>=, and ~. This rule does not ban the use of & and | for intersection and union types.

Rationale

Bitwise operators are often typos - for example bool1 & bool2 instead of bool1 && bool2. They also can be an indicator of overly clever code which decreases maintainability.

Config

Not configurable.

Examples
"no-bitwise": true
