prettier-elastic

3.2.5 verified Sat Apr 25 auth: no javascript

A fork of Prettier (v3.2.5) that customizes formatting for `var`, `let`, and `const` declarations by aligning variable names in multi-declaration statements. It provides an alternative style where commas appear at the start of continuation lines, aligning values vertically. The package supports all Prettier languages (JavaScript, TypeScript, CSS, HTML, etc.) and is maintained by medikoo. It tracks upstream Prettier releases and includes TypeScript type definitions. Key differentiator: solves dissatisfaction with Prettier's default declaration alignment, offering a more tabular format without plugins.

Common errors

error Error [ERR_MODULE_NOT_FOUND]: Cannot find module 'prettier-elastic' ↓

cause Package not installed or wrong import path in ESM.

fix

Run: npm install prettier-elastic. Then import correctly: import { format } from 'prettier-elastic'.

error TypeError: prettier.format is not a function ↓

cause Using default import incorrectly in CommonJS.

fix

Use: const prettier = require('prettier-elastic'); correctly exports format as a method.

error SyntaxError: Unexpected token 'export' ↓

cause Using ESM import in a CommonJS file without 'type': 'module'.

fix

Add 'type': 'module' to package.json, or use require() syntax.

error Error: Cannot find module './parser-babel' ↓

cause Plugin resolution issue; likely missing parser dependencies.

fix

Ensure @babel/parser is installed, or use parser: 'babel' which is built-in.

Warnings

breaking This is a fork with different output than standard Prettier for var/let/const multi-declarations. ↓

fix Do not use this if standard Prettier behavior is required. Alternatively, use 'prettier' package and configure plugins.

deprecated Deprecated '--use-tabs' option may behave differently; prefer 'tabWidth' and 'useTabs' config. ↓

fix Use 'tabWidth' and 'useTabs' in your prettier config instead of --use-tabs.

gotcha The package name is 'prettier-elastic', not 'prettier'. Installing the wrong package will not give the custom formatting. ↓

fix Run: npm install prettier-elastic and import from 'prettier-elastic'.

gotcha Version numbers do not necessarily match upstream Prettier; check changelog for exact mapping. ↓

fix Verify behavior against expected Prettier version via tests.

Install

npm install prettier-elastic

yarn add prettier-elastic

pnpm add prettier-elastic

Imports

format
wrong
```
const prettier = require('prettier-elastic'); prettier.format(src, opts);
```
correct
```
import { format } from 'prettier-elastic'
```
ESM import is recommended; the package also supports CommonJS. The format function is the same API as Prettier.

check

wrong

const { check } = require('prettier-elastic');

correct

import { check } from 'prettier-elastic'

check function returns a boolean; use with --check CLI flag.

default (package)
wrong
```
const prettier = require('prettier-elastic');
```
correct
```
import prettier from 'prettier-elastic'
```
Default export is an object with format, check, resolveConfig, etc. ESM default import works.
formatWithCursor
```
import { formatWithCursor } from 'prettier-elastic'
```
Available in both ESM and CJS; same as upstream.

resolveConfig

wrong

const { resolveConfig } = require('prettier-elastic');

correct

import { resolveConfig } from 'prettier-elastic'

Async function; works identically to Prettier's resolveConfig.

Quickstart

Demonstrates the core formatting difference: var declarations with aligned equals and comma-first line continuation.

import { format } from 'prettier-elastic';

const code = `var eloBar = require("elo-bar"),
  foo = require("foo"),
  otherThing = require("other-thing");`;

const formatted = format(code, { parser: 'babel' });
console.log(formatted);
// Output:
// var eloBar     = require("elo-bar")
//   , foo        = require("foo")
//   , otherThing = require("other-thing");
