Isomor Server

3.0.4 verified Fri May 01 auth: no javascript

Server-side library for isomor, a framework that abstracts frontend-backend communication layers to allow direct function calls from UI code. Version 3.0.4 is current; release cadence is irregular. Key differentiators: automatic layer generation via Babel transpilation, eliminates REST/GraphQL overhead, strong TypeScript consistency by colocating frontend and backend code. Targets Node >=11.

error Property 'start' does not exist on type 'typeof IsomorServer' ↓

cause Forgetting to instantiate the class, using it as a static method.

Warnings

Imports

IsomorServer

wrong

const { IsomorServer } = require('isomor-server')

correct

import { IsomorServer } from 'isomor-server'

ESM-only package; CJS require will not work.

default import

wrong

const isomorServer = require('isomor-server')

correct

import isomorServer from 'isomor-server'

Default export is named export; prefer named import for clarity.

type imports

wrong

import { IsomorServerOptions } from 'isomor-server' (if used at runtime)

correct

import type { IsomorServerOptions } from 'isomor-server'

Types are exported; use type-only imports to avoid runtime inclusion.

Quickstart

Creates and starts an IsomorServer instance on port 4000.

import { IsomorServer } from 'isomor-server';

const server = new IsomorServer({
  port: 4000,
  // other options
});

server.start();
