ngx-zombie-compiler

library0.3.0jsnpmunverified

Fast JiT compiler for Angular unit testing that reuses compiled results across specs to reduce execution time. Current stable version 0.3.0, compatible with Angular 4.2+. Unlike default Angular TestingCompiler which compiles modules per spec, this compiler outlives the default and caches compiled components. Ships TypeScript types. Low release cadence; last release in 2017. Useful for Angular CLI projects (edit src/test.ts). Few alternatives exist for this niche optimization.

Verified usage

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

ZOMBIE_COMPILER_PROVIDERS

✓ import { ZOMBIE_COMPILER_PROVIDERS } from 'ngx-zombie-compiler';

✗ const { ZOMBIE_COMPILER_PROVIDERS } = require('ngx-zombie-compiler');

Package provides ESM and CJS; default export is not available.

ZombieCompiler

✓ import { ZombieCompiler } from 'ngx-zombie-compiler';

✗ import ZombieCompiler from 'ngx-zombie-compiler';

Named export, not default.

ZombieJitCompiler

✓ import { ZombieJitCompiler } from 'ngx-zombie-compiler';

Internal class not typically needed; use ZOMBIE_COMPILER_PROVIDERS.

Configures TestBed to use the zombie compiler, reusing compiled results across specs.

import { TestBed, getTestBed } from '@angular/core/testing'; import { ZOMBIE_COMPILER_PROVIDERS } from 'ngx-zombie-compiler'; beforeEach(() => { getTestBed().configureCompiler({ providers: ZOMBIE_COMPILER_PROVIDERS, }); }); // Then write your tests normally

Debug

Known issues

breakingVersion 0.3.0 requires Angular 4.2.0+ due to breaking change in JitCompiler constructor. Older versions incompatible.

fix

Upgrade to ngx-zombie-compiler@0.3.0 and ensure @angular/core and @angular/compiler are >=4.2.0.

affects: <0.3.0

deprecatedPackage has not been updated since Angular 4. May not work with Angular 5+ due to changes in compiler internals.

fix

Consider testing with Angular 5+; if compilation fails, look for alternatives or fork.

affects: >=0.3.0

gotchaZOMBIE_COMPILER_PROVIDERS must be provided in beforeEach(), not once at top level, to avoid cross-test contamination.

fix

Call getTestBed().configureCompiler({ providers: ZOMBIE_COMPILER_PROVIDERS }) inside each beforeEach() or in a setup function per test suite.

affects: all

gotchaDoes not support AOT compilation; only JiT. AOT tests may need jasmine or jest configuration.

fix

For AOT, use Angular's default TestBed or @angular/platform-browser-dynamic testing utilities.

affects: all

Errors

Common errors & fixes

Error: Can't resolve 'ngx-zombie-compiler'

Package not installed or typo in import path.

fix

npm install ngx-zombie-compiler --save-dev

TypeError: TestBed.configureCompiler is not a function

Using old Angular version where TestBed.configureCompiler does not exist.

fix

Ensure @angular/core is version 4.x.x or later. For Angular 2.x, use deprecated methods.

Error: StaticInjectorError[ZombieCompiler]: NullInjectorError: No provider for JitCompiler!

Missing @angular/compiler peer dependency.

fix

npm install @angular/compiler@^4.2.0
