library1.8.28jsnpmunverified

The most-data package (v1.8.28) is the ORM module for MOST Web Framework v1.x, providing JSON-schema-based data modeling, constraints, triggers, associations, privileges, and data views for building scalable data-driven Node.js applications. It supports RDBMS backends with a query builder and OData compatibility. Note that the project recommends migrating to v2.x (Blueshift, @themost package), as v1.x is in maintenance mode. Compared to other ORMs, it emphasizes a schema-first approach with built-in access control and expandable relations.

Code

Verified usage

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

DataContext

✓ import { DataContext } from 'most-data';

✗ const DataContext = require('most-data');

Package supports both ESM and CJS, but ESM is preferred for modern Node.js. CJS require will work, but named exports may be missed.

SqliteAdapter

✓ import { SqliteAdapter } from 'most-data';

✗ const SqliteAdapter = require('most-data').SqliteAdapter;

Named export; available in both ESM and CJS.

MemoryAdapter

✓ import { MemoryAdapter } from 'most-data';

✗ const MemoryAdapter = require('most-data').MemoryAdapter;

For in-memory data store, useful for testing.

Quickstart showing how to initialize a DataContext with SQLite adapter, open connection, query a model, and close.

import { DataContext, SqliteAdapter } from 'most-data'; const context = new DataContext(); context.setAdapter('default', new SqliteAdapter()); await context.open(); const users = await context.model('User').getItems(); console.log(users); await context.close();

Debug

Known issues

deprecatedmost-data v1.x is deprecated; upgrade to @themost framework v2.x.

fix

Migrate to @themost packages (https://github.com/themost-framework/themost).

affects: >=1.0.0 <2.0.0

gotchaSchema models must be registered before context.open(); otherwise queries fail silently.

fix

Ensure all model schemas are loaded via context.use() or included in the models directory before opening context.

affects: >=1.0.0

gotchaDefault adapter is 'memory'; using SQLite requires explicit adapter set and sqlite3 native addon.

fix

Install sqlite3 package and call context.setAdapter('default', new SqliteAdapter());

affects: >=1.0.0

Errors

Common errors & fixes

Error: No adapter configured for data source 'default'

Trying to open context without setting an adapter.

fix

Call context.setAdapter('default', new SqliteAdapter()) before context.open().

TypeError: context.model is not a function

Import/require not resolving to the correct DataContext class or using an older version.

fix

Ensure you import DataContext from 'most-data' and instantiate correctly: new DataContext().

Error: Cannot find module 'sqlite3'

SqliteAdapter requires the 'sqlite3' native module but it is not installed.

fix

Run npm install sqlite3 --save
