isomor-ng-nest

2.7.0 verified Fri May 01 auth: no javascript

isomor-ng-nest v2.7.0 is a frontend/backend library for the isomor ecosystem, enabling direct function calls from UI to server without explicit API layers (REST/GraphQL). It uses Babel transpilation to separate frontend and backend code within a single project. Supports Node >=11 and ships TypeScript types. It is part of a set of packages for isomorphic TypeScript development with Angular (ng) and NestJS (nest) integrations. Release cadence is irregular, tied to isomor updates.

Common errors

error Cannot find module 'isomor-ng-nest' or its corresponding type declarations. ↓

cause Missing npm install or TypeScript not resolving the package types.

fix

Run npm install isomor-ng-nest isomor and ensure tsconfig.json includes "esModuleInterop": true.

error TypeError: isomorNgNest is not a function ↓

cause Importing as named export instead of default export.

fix

Use import isomorNgNest from 'isomor-ng-nest' (default import).

error Cannot find name 'AppModule'. ↓

cause AppModule not imported or defined in the file.

fix

Import or define the NestJS AppModule before using it in the configuration.

error Error: isomor requires Node >=11 ↓

cause Running on an older Node.js version.

fix

Upgrade Node.js to v11 or higher.

Warnings

gotcha isomor-ng-nest requires isomor as a peer dependency. Ensure isomor is installed at the same version or compatible. ↓

fix npm install isomor@^2.7.0

breaking In v2.0.0, the API changed from a class-based to a function-based initialization. Old code using `new IsomorNgNest()` will break. ↓

fix Replace `new IsomorNgNest()` with the functional `isomorNgNest()` export.

deprecated The `NestServer` export is deprecated in favor of inline configuration within `isomorNgNest()`. ↓

fix Use the `server` property directly in the config object.

gotcha TypeScript strict mode may cause issues with emitted client code due to complex generics. Use `skipLibCheck: true` as workaround. ↓

fix Add `"skipLibCheck": true` to tsconfig.json

breaking Node.js version >=11 required; earlier versions are not supported and will throw runtime errors. ↓

fix Upgrade Node.js to v11 or later.

Quickstart

Shows how to set up isomor-ng-nest with a NestJS backend and generate client-side code.

import isomorNgNest from 'isomor-ng-nest';

// Initialize isomor with NestJS
const app = await isomorNgNest({
  server: {
    port: 3000,
    module: AppModule
  },
  client: {
    output: './src/generated-client.ts'
  }
});

app.start();
