How to use CryptoJS with Angular 2 and TypeScript in WebPack build environment?

Related searches

There are a whole bunch of questions around using the CryptoJS library with Angular 2 but most assume use of SystemJS and all seem out of date with the current version of TypeScript. Can anybody give clear, simple instructions on how to use the CryptoJS library with Angular 2 and TypeScript.

I've installed CryptoJS using npm install crypto-js.

I've tried the recommended typings install crypto.js --ambient --save but this simply gives a warning about --ambient being deprecated and to use --global instead.

I've used --global instead but that then gives an error saying no typings were available!

Any advice to someone new to WebPack, NodeJS AND TypeScript would be appreciated. I have the CryptoJS library installed under node_modules folder but any "sensible" attempts to "import" CryptoJS fail with "Module not found".

crypto-js, How to use CryptoJS with Angular 2 and TypeScript in WebPack build environment? - angular. Modern Angular is built using Typescript which is the recommended language to build Angular applications with. Typescript provides great tooling options, better code readability and brings most of the usefulness of a good statically-typed language to the Javascript ecosystem.

Here is the simplest step-by-step install and using example (working in nativescript/typescript/angular project):

npm install crypto-js

then:

npm install --save @types/crypto-js

Import in some component:

import * as crypto from "crypto-js";

And use it:

crypto.DES.decrypt("Your secret", "YOUR_CRYPTO_KEY");

在WebPack构建环境中如何在Angular 2和TypeScript中使用CryptoJS?, How to use CryptoJS with Angular 2 and TypeScript in WebPack build environment? 由 浪尽此生 提交于2019-12-11 05:52:15� TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. In this guide we will learn how to integrate TypeScript with webpack. Basic Setup. First install the TypeScript compiler and loader by running: npm install--save-dev typescript ts-loader. Now we'll modify the directory structure & the configuration files: project

The crypto-js package in npm has no built-in types and no longer maintained.

You can try this, the same as crypto-js with TypeScript support and ES6 module: https://www.npmjs.com/package/crypto-es.

Crypto js angular 6, crypto-js Build Status ES6 import for typical API call signing use case: import sha256 from 'crypto-js/sha256';. import hmacSHA512 from 'crypto-js/hmac- sha512'; console.log(decryptedData); // [{id: 1}, {id: 2}] CryptoJS might does not run in some JavaScript environments without native crypto module. By using a TypeScript class for EnvService, we can rely on typing (and typeahead support) when working with environment values in our favorite IDE. How sweet is that! Let's use Angular CLI to create an env.service.ts file for our EnvService class: $ ng generate service env and replace its contents with:

If your TypeScript file runs in the browser, then there is no process.env, so you cannot even access it at runtime. You could use a tool like Webpack to replace references to process.env variables in the compiled file with their respective values at build time - but that still is not TypeScript's doing.

  • Thanks. It was the "dt~" I was missing. It makes sense once you realise that the "source" the message is warning about is added by prefixing with the ~ The complete answer as to how to use CryptoJS with Angular2 and TypeScript was hidden in this "import" statement I found elsewhere. Other answers implying import {CryptoJS} from 'crypto-js' wouid work just failed. import * as CryptoJS from 'crypto-js';
  • You are totally right. I remember me having the same problems with dt~ prefixes. The import problems you are having are related to angular-cli, because they were using SystemJS prevously. The first way of importing was valid for SystemJS setups.
  • This creates a folder for cryptoJS, but the index.js says that global exports are not possible unless at top level. I scoured the web for a solution/alternative to this problem, but I couldn't really find a conclusive answer. It's the same starting situation for me as for the OP: I have CryptoJS installed in node_modules, but can't import it. To add, I can't install as global module because: typings ERR! message Attempted to compile "crypto-js" as a global module, but it looks like an external modu le. You'll need to remove the global option to continue.
  • Seems like crypto-js typings are not global anymore (I am not sure, haven't used typings in a while). Consider asking separate question. Also, if you run typescript >2.0, check out @types (stackoverflow.com/questions/39261204/typings-vs-types-npm-scope).
  • @Arek-Żelechowski is correct, you should now use npm install --save @types/crypto-js
  • This way crashes for me in prod mode. I think there must be also included scripts
  • I think you will end up with this issue github.com/angular/angular-cli/issues/…. Correct me if I am wrong?
  • There is no need for using --save flag when installing types, why not install them only for development?
