Rule: quotemark

Notes
- Has Fix
Config
Five arguments may be optionally provided:
-
"single"
enforces single quotes. -
"double"
enforces double quotes. -
"backtick"
enforces backticks. -
"jsx-single"
enforces single quotes for JSX attributes. -
"jsx-double"
enforces double quotes for JSX attributes. -
"avoid-template"
forbids single-line untagged template strings that do not contain string interpolations. Note that backticks may still be used if"avoid-escape"
is enabled and both single and double quotes are present in the string (the latter option takes precedence). -
"avoid-escape"
allows you to use the "other" quotemark in cases where escaping would normally be required. For example,[true, "double", "avoid-escape"]
would not report a failure on the string literal'Hello "World"'

import type { RenderData } from '@storybook/router';
- Read upRead up
- Exclude checks
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`;`.

Rule: no-empty
Disallows empty blocks.
Blocks with a comment inside are not considered empty.
Rationale
Empty blocks are often indicators of missing code.
Config

If allow-empty-functions

- Read upRead up
- Exclude checks
Rule: align
Enforces vertical alignment.
Rationale
Helps maintain a readable, consistent style in your codebase.
Consistent alignment for code statements helps keep code readable and clear. Statements misaligned from the standard can be harder to read and understand.
Notes
- Has Fix
Config
Five arguments may be optionally provided:
-
"parameters"
checks alignment of function parameters. -
"arguments"
checks alignment of function call arguments. -
"statements"
checks alignment of statements. -
"members"
checks alignment of members of classes, interfaces, type literal, object literals and object destructuring. -
"elements"
checks alignment of elements of array literals, array destructuring and tuple types.

}, {} as Record<string, () => void>);
- Read upRead up
- Exclude checks
Rule: no-object-literal-type-assertion
Forbids an object literal to appear in a type assertion expression.
Casting to any
or to unknown
is still allowed.
Rationale
Always prefer const x: T = { ... };
to const x = { ... } as T;
.
The type assertion in the latter case is either unnecessary or hides an error.
The compiler will warn for excess properties with this syntax, but not missing required fields.
For example: const x: { foo: number } = {}
will fail to compile, but
const x = {} as { foo: number }
will succeed.
Additionally, the const assertion const x = { foo: 1 } as const
,
introduced in TypeScript 3.4, is considered beneficial and is ignored by this rule.
Notes
- TypeScript Only
Config
One option may be configured:
