nodejs 使用了 global 标识符来访问全局作用域。这样就导致了一个问题,如果一个库的作者想要暴露方法到全局空间,就需要探测当前的环境是浏览器还是 nodejs,浏览器里还分代码是否在 worker 进程里, 要加 if(typeof window === 'undefined') else if(typeof self === 'undefined') 之类的判断,最不济就用顶...

For Node.js this package provides two sets of globals: globals.nodeBuiltin: Globals available to all code running in Node.js. These will usually be available as properties on theglobalThisobject and includeprocess,Buffer, but not CommonJS arguments likerequire. See:https://nodejs.org/api/globa...
Transforms ESM import statements to work with current CommonJS limitations in Node’s vm.Uses Node’s vm module to execute JavaScript ⚠️ The node:vm module is not a security mechanism. Do not use it to run untrusted code. codeGeneration (e.g. eval) is disabled by default; use ...
about the used references for encoding the data in the symbol. Current implementation consists all well known charset encodings. Currently, it is used only for QR 2D barcode. Example let generator = new BarcodeGenerator(EncodeTypes.QR); generator.setCodeText("12345TEXT"); generator.getParameters...
globals.node: A combination of the globals fromnodeBuiltinplus all CommonJS arguments ("CommonJS module scope"). See:https://nodejs.org/api/modules.html#modules_the_module_scope When analyzing code that is known to run outside of a CommonJS wrapper, for example, JavaScript modules,nodeBuilt...
