nohm

library3.0.0jsnpmunverified

Nohm is an ORM for Node.js and Redis, written in TypeScript with first-class typings. It supports standard ORM features (validate, store, search, sort, link/unlink, delete), dynamic relations defined at runtime, shared validations with the browser, and PubSub-based ORM events for live updates. The project is currently unmaintained (last release 3.0.0) and has known security vulnerabilities. It requires Redis >= 2.4 and Node >= 8.

Code

Verified usage

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

Nohm

✓ import { Nohm } from 'nohm'

✗ import nohm from 'nohm'

Nohm is a named export, not a default export. In v3 it's ESM-only.

NohmModel

✓ import { NohmModel } from 'nohm'

✗ const NohmModel = require('nohm').NohmModel

Use destructured import. CommonJS require still works but is deprecated.

ValidationError

✓ import { ValidationError } from 'nohm'

ValidationError is exported for catching validation errors in try/catch blocks.

Shows ESM import of Nohm, NohmModel, ValidationError; Redis client creation; model class definition with static properties; model save with validation error handling.

import { Nohm, NohmModel, ValidationError } from 'nohm'; import { createClient } from 'redis'; const client = createClient({ url: process.env.REDIS_URL ?? 'redis://localhost:6379', }); class User extends NohmModel { get displayName() { return `${this.property('firstname')} ${this.property('lastname')}`; } } User.modelName = 'User'; User.definitions = { firstname: { type: 'string', validations: ['notEmpty'], }, lastname: { type: 'string', validations: ['notEmpty'], }, }; Nohm.setClient(client); Nohm.setPrefix('myapp'); async function main() { await Nohm.ready(); const user = new User({ firstname: 'John', lastname: 'Doe' }); try { await user.save(); console.log('Saved user with id', user.id); } catch (err) { if (err instanceof ValidationError) { console.error('Validation failed:', err.message); } else { console.error(err); } } await client.quit(); } main();

Debug

Known issues

breakingv3 is ESM-only. If you are using CommonJS (require), you must switch to dynamic import or upgrade to Node >= 16 with ESM support.

fix

Use import { Nohm } from 'nohm' or wrap require in a dynamic import: const { Nohm } = await import('nohm');

affects: 3.0.0

breakingThe 'redis' client must now be created using 'createClient()' and passed via 'Nohm.setClient()'. Old v2-style automatic connection is removed.

fix

Create a redis client with 'createClient()' and call 'Nohm.setClient(client)' before using models.

affects: 3.0.0

breakingNohmModel.definitions no longer accepts shorthand 'type' strings; all types must be explicit strings or functions.

fix

Use 'type: 'string'' instead of 'type: String' and ensure all definition objects are complete.

affects: 3.0.0

deprecatedThe 'nohm.model()' function is deprecated. Use ES6 class extending NohmModel instead.

fix

Define a class that extends NohmModel and set static modelName and definitions.

affects: >=3.0.0

gotchaDue to known vulnerabilities (Snyk badge shows high severity), be cautious when using in production.

fix

Evaluate alternatives like redis-om or ioredis based ORMs.

affects: >=3.0.0

Errors

Common errors & fixes

Error: Cannot find module 'nohm'

Nohm v3 is ESM-only and requires Node >= 12 with --experimental-modules or Node >= 16.

fix

Update to Node >= 16 and use 'import { Nohm } from 'nohm'' or enable ESM via 'type': 'module' in package.json.

TypeError: Nohm.setClient is not a function

You might be importing the default export instead of the named export.

fix

Use correct import: import { Nohm } from 'nohm' instead of import Nohm from 'nohm'.

Redis client is not set. Call Nohm.setClient() before using models.

You forgot to set the redis client with Nohm.setClient() after import.

fix

Call Nohm.setClient(redisClient) immediately after creating the redis client.

Dependencies

redisrequiredNohm requires the 'redis' package to connect to Redis. It uses redis client internals and expects the client to be created via 'redis.createClient()'.
