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.
Examples
"align": true,parameters,statements
Schema

"type": "string",
"enum": [
"arguments",

unused expression, expected an assignment or function call Open
import type { CodegenConfig } from "@graphql-codegen/cli";
- Read upRead up
- Create a ticketCreate a ticket
- 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`;`.
Examples
"no-unused-expression": true

Rule: no-return-await
Disallows unnecessary return await

Rationale
An async function always wraps the return value in a Promise.
Using return await
just adds extra time before the overreaching promise is resolved without changing the semantics.

Config
Not configurable.

Notes
- Has Fix
Config
One of the following arguments must be provided:
-
"always"

- Read upRead up
- Create a ticketCreate a ticket
- Exclude checks
Rule: prefer-for-of
Recommends a 'for-of' loop over a standard 'for' loop if the index is only used to access the array being iterated.
Rationale
A for(... of ...) loop is easier to implement and read when the index is not needed.
Config
Not configurable.
Examples
"prefer-for-of": true

- Read upRead up
- Create a ticketCreate a ticket
- Exclude checks
Rule: prefer-conditional-expression
Recommends to use a conditional expression instead of assigning to the same thing in each branch of an if statement.
Rationale
This reduces duplication and can eliminate an unnecessary variable declaration.
Config
If check-else-if
is specified, the rule also checks nested if-else-if statements.

- Exclude checks
Rule: no-empty
Disallows empty blocks.
Blocks with a comment inside are not considered empty.

- Read upRead up
- Create a ticketCreate a ticket
- Exclude checks
Rule: ban-comma-operator
Disallows the comma operator to be used.
Read more about the comma operator here.
Rationale
Using the comma operator can create a potential for many non-obvious bugs or lead to misunderstanding of code.
Examples
foo((bar, baz)); // evaluates to 'foo(baz)' because of the extra parens - confusing and not obvious
switch (foo) {
case 1, 2: // equals 'case 2' - probably intended 'case 1: case2:'
return true;
case 3:
return false;
}
let x = (y = 1, z = 2); // x is equal to 2 - this may not be immediately obvious.
Examples
"ban-comma-operator": true
