The Base Library is a polyfilling abstraction layer that allows to use the identical code bases among the Web Browser and node.js without having to integrate a third-party build toolchain or build workflow.

The intention of this library is to have an ECMAScript Modules abstraction that allows to include otherwise globally defined data types via a single file, and allows cross-context and cross-sandbox serialization of data types, which otherwise wouldn't be possible.

As data type instances in ECMAScript runtimes are instanciated per-sandbox, this library also includes is(Datatype) replacements for typeof and instanceof, and it is recommended to use the [Symbol.toStringTag] on the prototype of custom Function Templates to stay compatible.

The Base Library is using a simple make.mjs script that generates the /build folder.

The make.mjs is called by other build scripts, too:

• Browser's make.mjs
• Covert's make.mjs
• Stealth's make.mjs

cd /path/to/stealth;

# Build the Base Library
node ./base/make.mjs;

# Afterwards, simply copy/paste the generated ESM module and use import syntax
# cp ./base/build/browser.mjs ./to/a/browser/project/extern/base.mjs;
# cp ./base/build/node.mjs    ./to/a/node/project/extern/base.mjs;

The Base Library exports a default export that contains an Object with all exports. Additionally, all methods and data types are exported as named exports.

// Import Base Library
import base from './base/index.mjs';

// Import selected named exports
import { console, Emitter, isEmitter } from './base/index.mjs';

// Import Base Library
import base from 'stealth/base';

// Import selected named exports
import { console, Emitter, isEmitter } from 'stealth/base';
