Fixing a NodeJS Digital Envelope Routines Error

#node #errors #hack

In my journey to learn Rust, I've decided to pick up this book called "Practical Rust Web Projects" by Shing Lyu.

In the last chapter, you walk through an example of packaging a WebAssembly module using wasm-pack and using the .wasm binary in a NodeJS application. On the step where I needed to compile the application, I ran into the following error:

$ npm run build > create-wasm-app@0.1.0 build > webpack --config webpack.config.js node:internal/crypto/hash:71 this[kHandle] = new _Hash(algorithm, xofLen); ^ Error: error:0308010C:digital envelope routines::unsupported at new Hash (node:internal/crypto/hash:71:19) at Object.createHash (node:crypto:133:10) at module.exports (/Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/webpack/lib/util/createHash.js:135:53) at NormalModule._initBuildHash (/Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/webpack/lib/NormalModule.js:417:16) at handleParseError (/Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/webpack/lib/NormalModule.js:471:10) at /Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/webpack/lib/NormalModule.js:503:5 at /Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/webpack/lib/NormalModule.js:358:12 at /Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/loader-runner/lib/LoaderRunner.js:373:3 at iterateNormalLoaders (/Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/loader-runner/lib/LoaderRunner.js:214:10) at Array.<anonymous> (/Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/loader-runner/lib/LoaderRunner.js:205:4) at Storage.finished (/Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/enhanced-resolve/lib/CachedInputFileSystem.js:43:16) at /Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/enhanced-resolve/lib/CachedInputFileSystem.js:79:9 at /Users/paul/repos/Apress/practical-rust-web-projects/Ch06/hello-wasm/client/node_modules/graceful-fs/graceful-fs.js:78:16 at FSReqCallback.readFileAfterClose [as oncomplete] (node:internal/fs/read_file_context:68:3) { opensslErrorStack: [ 'error:03000086:digital envelope routines::initialization error' ], library: 'digital envelope routines', reason: 'unsupported', code: 'ERR_OSSL_EVP_UNSUPPORTED' } Node.js v18.7.0

After a bit of Googling, I ran across someone suggesting to run the following command:

$ export NODE_OPTIONS=--openssl-legacy-provider
Enter fullscreen mode Exit fullscreen mode

Then run the build command again, and it compiled 🎉

$ npm run build > create-wasm-app@0.1.0 build > webpack --config webpack.config.js Hash: 1707689247fe60c788af Version: webpack 4.42.0 Time: 67ms Built at: 11/08/2022 7:50:56 PM Asset Size Chunks Chunk Names 0.bootstrap.js 5.31 KiB 0 [emitted] 7e852f2346d8cc54b57a.module.wasm 296 bytes 0 [emitted] [immutable] bootstrap.js 11 KiB main [emitted] main index.html 297 bytes [emitted] Entrypoint main = bootstrap.js [../pkg/hello_wasm.js] 81 bytes {0} [built] [../pkg/hello_wasm_bg.js] 784 bytes {0} [built] [../pkg/hello_wasm_bg.wasm] 270 bytes {0} [built] [./bootstrap.js] 279 bytes {main} [built] [./index.js] 51 bytes {0} [built] [./node_modules/webpack/buildin/harmony-module.js] (webpack)/buildin/harmony-module.js 573 bytes {0} [built]

This is definitely not the proper fix in a production scenario, but good enough to get me through the example 😉

Cheers!

I'd like to know what the proper fix in a production scenario would be. I encountered this problem while working with an express app in NodeJS.

I have not tested this but seems like moving to LTS version of NodeJS or upgrading react-scripts to version 5.x or higher. freecodecamp.org/news/error-error-...

This new PR worked for me: github.com/rustwasm/create-wasm-ap...
(In the context of learning Rust + wasm.)

I made the changes manually, then ran npm install, after which npm run start worked as expected.
