ESLint

eslint-plugin-absolute ships 27 rules that enforce AbsoluteJS conventions — SSR-safe paths, react-spring-friendly styling, leaner TypeScript, and consistent project structure. Each rule has its own page with examples, options, and guidance below.

#Installation

Install the plugin, register it under the absolute namespace, and enable the rules you want:

BASH
bun add --dev eslint-plugin-absolute
JS
// eslint.config.js
import absolute from 'eslint-plugin-absolute';

export default [
	{
		plugins: { absolute },
		rules: {
			'absolute/no-import-meta-path': 'error',
			'absolute/sort-keys-fixable': 'error',
			'absolute/no-explicit-return-type': 'error'
		}
	}
];

#Legend

ProblemReports a likely bug or correctness issue.
SuggestionReports a stylistic or best-practice improvement.
FixableReports can be repaired automatically with eslint --fix.
Type-awareUses the TypeScript type checker; set parserOptions.project.

#React & JSX

7 rules.

RuleNotes

Disallow variables that are only passed to a single custom child component; move them into that component instead.

—

Warn when JSX elements are nested too deeply, suggesting refactoring into a separate component.

—

Enforce using anchor tags for navigation instead of buttons whose onClick handlers change the path.

—

Disallow nested functions that return non-component, non-singular JSX, to enforce one component per file.

—

Prefer the logical && operator over a ternary with null/undefined for conditional JSX rendering.

—

Flag unnecessary <div> wrappers that enclose a single JSX element.

—

Enforce that the key prop is only used on elements rendered as part of an array mapping.

—

#Styling

4 rules.

RuleNotes

Disallow inline style objects with too many keys and encourage extracting them.

—

Disallow grouping CSS style objects in a single export; export each style separately.

—

Objects typed as CSSProperties must not include a 'transition' property, which conflicts with react-spring.

—

Warn when a component file (.tsx/.jsx) contains a style object typed as CSSProperties; move it to a style file.

—

#react-spring

1 rule.

RuleNotes

Enforce correct naming for useSpring and useSprings hook destructuring (<base>Springs / <base>Api).

—

#TypeScript

5 rules.

RuleNotes

Require explicit type annotations for object literals and arrays of object literals.

—

Disallow explicit return type annotations on functions, except for type-predicate guards and inline object-literal returns.

—

Disallow inline object type literals on annotations; prefer extracting them to a named type alias.

—

Disallow type annotations on variable declarations whose initializer already has the same inferred type.

FixTypes

Disallow identity aliases that rename a type or value without transforming it.

—

#Angular

2 rules.

RuleNotes

Disallow defining more than one Angular feature class (@Component, @Directive, @Pipe, @Injectable, @NgModule) per file.

—

Disallow nondeterministic values in Angular render paths that can cause SSR hydration mismatches.

—

#Imports & Exports

3 rules.

RuleNotes

Prefer inlining export at a declaration site over a trailing export { name } statement for local declarations.

Fix

Enforce that top-level export declarations are sorted by exported name, optionally variables before functions.

Fix

Enforce sorted keys in object literals with a comment-preserving auto-fix for provably safe cases.

Fix

#Code Quality

5 rules.

RuleNotes

Disallow too many nested blocks, except when the block only contains an early exit (return or throw).

—

Disallow variable names shorter than the configured minimum length, unless an outer variable with a longer name starting with the same characters exists.

—

Disallow deriving filesystem paths from a module's own location, which break when the server is bundled.

—

Disallow catch blocks that contain only comments or no-op statements.

—

Disallow functions that take no parameters and just return an object literal, unless used as a callback.
