mysql-error-keys

library0.1.3jsnpmunverified

A curated list of constants for MySQL error key strings (e.g., 'ER_DUP_ENTRY'). Current stable version 0.1.3, with infrequent releases. Provides both named exports and a default object with all keys for use in Node.js and browser environments. Differentiates from raw error code maps by offering TypeScript type definitions and a simple constant-based approach to avoid magic strings in error handling.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

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

mek

✓ import { mek } from 'mysql-error-keys'

✗ const mek = require('mysql-error-keys').mek

Default export is not an object; use named import for the mek object.

ER_DUP_ENTRY

✓ import { ER_DUP_ENTRY } from 'mysql-error-keys'

✗ import { ER_DUP_ENTRY as something } from 'mysql-error-keys'

Named exports match MySQL error key strings exactly.

require

✓ const { ER_DUP_ENTRY } = require('mysql-error-keys')

✗ const mek = require('mysql-error-keys').default

CommonJS users can destructure or use the default export directly.

Shows how to import the mek object and use a constant for error comparison, avoiding raw strings.

import { mek } from 'mysql-error-keys'; try { // some operation that might cause a MySQL duplicate entry } catch (err: any) { if (err.code === mek.ER_DUP_ENTRY) { console.log('Duplicate entry, handle accordingly.'); } }

Debug

Known issues

gotchaThe package version is 0.1.x, API may change without major version bump.

fix

affects: *

gotchaImporting { mek } is the recommended way, but some users mistakenly try import * as mek from 'mysql-error-keys' which fails.

fix

Errors

Common errors & fixes

TypeError: Cannot read properties of undefined (reading 'ER_DUP_ENTRY')

Used default import without the mek wrapper.

fix

Use import { mek } from 'mysql-error-keys' and then mek.ER_DUP_ENTRY.

SyntaxError: The requested module 'mysql-error-keys' does not provide an export named 'default'

Tried import mek from 'mysql-error-keys' which expects a default export that doesn't exist.

fix

Use import { mek } from 'mysql-error-keys' instead.

Module not found: Error: Can't resolve 'mysql-error-keys'

Package not installed or incorrectly imported in a browser bundler without proper configuration.

fix

Install package with npm install mysql-error-keys and ensure bundler can resolve Node modules.
