babel-helper-simple-access

library7.0.0-beta.3jsnpmunverified

A Babel helper package (currently at v7.0.0-beta.3) that transforms complex assignment patterns (e.g., `i += 1`, `--i`) into simple assignments for easier AST manipulation. It is part of the Babel ecosystem, primarily used internally by Babel plugins. Unlike general-purpose AST utilities, it specifically handles converting compound assignments and unary mutations to straightforward `i = i + 1` style assignments. This package is in beta and likely deprecated in favor of modern Babel 8 helpers.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import simpleAccess from 'babel-helper-simple-access'

✗ const simpleAccess = require('babel-helper-simple-access').default

Default export; CJS require does not need .default if using default export. Use ESM for clarity.

simpleAccess

✓ import simpleAccess from 'babel-helper-simple-access'

✗ import { simpleAccess } from 'babel-helper-simple-access'

The module exports a single function as default export, not named. Removing braces is required.

types (from @babel/types)

✓ import * as t from '@babel/types'

✗ import t from '@babel/types'

The helper works with Babel types. Typically used alongside @babel/types for AST node creation.

Demonstrates using simpleAccess to convert a compound assignment into a simple assignment.

import simpleAccess from 'babel-helper-simple-access'; import * as t from '@babel/types'; // Example: convert `i += 1` to `i = i + 1` const ast = t.expressionStatement( t.assignmentExpression('+=', t.identifier('i'), t.numericLiteral(1)) ); simpleAccess(ast, [t.identifier('i')]); console.log(ast); // Now `ast` contains simple assignment // Note: This is a low-level helper; not intended for standalone use.

Known issues

deprecatedThis package is part of Babel 7 beta and is deprecated. Use Babel 8's internal helpers instead.

fix

Migrate to @babel/helper-simple-access if available, or use Babel 8 plugins.

affects: >=7.0.0-beta.3

gotchaThis helper does not handle destructuring patterns like `{ a } = foo`.

fix

Manually handle destructuring or use a different transformation pass.

affects: >=7.0.0-beta.3

breakingAPI may change in future versions; this package is experimental.

fix

Pin to a specific version and test thoroughly.

affects: >=7.0.0-beta.3

Errors

Common errors & fixes

TypeError: simpleAccess is not a function

Incorrect import: using named import instead of default import.

fix

Use `import simpleAccess from 'babel-helper-simple-access'` (default import).

Error: Cannot find module 'babel-helper-simple-access'

Package not installed or version mismatch.

fix

Run `npm install babel-helper-simple-access@7.0.0-beta.3` and ensure it's in package.json.
