Rule: semicolon

Enforces consistent semicolon usage at the end of every statement.

Notes

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".

Rule: no-shadowed-variable

Disallows shadowing variable declarations.

Rationale

When a variable in a local scope and a variable in the containing scope have the same name, shadowing occurs. Shadowing makes it impossible to access the variable in the containing scope and obscures to what value an identifier actually refers. Compare the following snippets:

const a = 'no shadow';
function print() {
    console.log(a);
}
print(); // logs 'no shadow'.

const a = 'no shadow';
function print() {
    const a = 'shadow'; // TSLint will complain here.
    console.log(a);
}
print(); // logs 'shadow'.

ESLint has an equivalent rule. For more background information, refer to this MDN closure doc.

Config

You can optionally pass an object to disable checking for certain kinds of declarations. Possible keys are "class", "enum", "function", "import", "interface", "namespace", "typeAlias" and "typeParameter". You can also pass "underscore" to ignore variable names that begin with _. Just set the value to false for the check you want to disable. All checks default to true, i.e. are enabled by default. Note that you cannot disable variables and parameters.

The option "temporalDeadZone" defaults to true which shows errors when shadowing block scoped declarations in their temporal dead zone. When set to false parameters, classes, enums and variables declared with let or const are not considered shadowed if the shadowing occurs within their temporal dead zone.

The following example shows how the "temporalDeadZone" option changes the linting result:

function fn(value) {
    if (value) {
        const tmp = value; // no error on this line if "temporalDeadZone" is false
        return tmp;
    }
    let tmp = undefined;
    if (!value) {
        const tmp = value; // this line always contains an error
        return tmp;
    }
}

Rule: label-position

Only allows labels in sensible locations.

This rule only allows labels to be on do/for/while/switch statements.

Rationale

Labels in JavaScript only can be used in conjunction with break or continue, constructs meant to be used for loop flow control. While you can theoretically use labels on any block statement in JS, it is considered poor code structure to do so.

Config

Not configurable.

• "check-space" requires that all single-line comments must begin with a space, as in // comment
  • note that for comments starting with multiple slashes, e.g. ///, leading slashes are ignored
  • TypeScript reference comments are ignored completely
• "check-lowercase" requires that the first non-whitespace character of a comment must be lowercase, if applicable.
• "check-uppercase" requires that the first non-whitespace character of a comment must be uppercase, if applicable.
• "allow-trailing-lowercase" allows that only the first comment of a series of comments needs to be uppercase.
  • requires "check-uppercase"
  • comments must start at the same position

Exceptions to "check-lowercase" or "check-uppercase" can be managed with object that may be passed as last argument.

One of two options can be provided in this object:

• "ignore-words" - array of strings - words that will be ignored at the beginning of the comment.
• "ignore-pattern" - string - RegExp pattern that will be ignored at the beginning of the comment.

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

{
  "type": "array",
  "items": {
    "type": "string",

      "allow-tagged-template"
    ]
