TypeError: crypto.hash is not a function | Dev Server not starting

[shivam28singh]

I am facing issue while starting a dev server using vite(7.0.4).
TypeError: crypto.hash is not a function
I researched and found browsers doesn't support crypto.hash function so tried to use polyfills. In the vite.config.js file, I have mentioned the fallback library "crypto-browserify" but it still shows the same error.

error when starting dev server: TypeError: crypto.hash is not a function at getHash (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/chunks/dep-DZ2tZksn.js:2788:21) at getLockfileHash (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/chunks/dep-DZ2tZksn.js:11673:9) at getDepHash (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/chunks/dep-DZ2tZksn.js:11676:23) at initDepsOptimizerMetadata (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/chunks/dep-DZ2tZksn.js:11137:53) at createDepsOptimizer (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/chunks/dep-DZ2tZksn.js:34586:17) at new DevEnvironment (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/chunks/dep-DZ2tZksn.js:35350:109) at Object.defaultCreateClientDevEnvironment [as createEnvironment] (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/chunks/dep-DZ2tZksn.js:35769:9) at _createServer (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/chunks/dep-DZ2tZksn.js:28344:132) at async CAC.<anonymous> (file:///D:/NewsFeedSystem/node_modules/vite/dist/node/cli.js:573:18)

delete node_modules and lock nothing happens

Resolution in my case:

I was building in CodeBuild (Amazon Linux 2), and the image hasn't been updated in a while to include newer versions of Node.

Vite 7 requires a relatively recent version of Node 20 / Node 22, so I added n 22.17.1 to my buildspec and it resolved my issue.

Perhaps you're facing a similar issue locally?

[LuiguiDev]

That work in my case too. Thanks.

[l-white]

This solution works perfectly in my case. Thank you @TotalTechGeek

[hcmlopes]

I had the same issue in my local environment. Changing my node version to 22.17.1 also resolved the problem for me.

[HalilRodoplu]

thank you solved my issue tho

[Ritesh1244]

i also got the same error , but it got fixed using node verson 20.19.0 or above -> i hope it helps

[hc0503]

Latest Vite requires node v22.17.1. Check and upgrade your node version

[Borber]

So how does bun fix this?

[elasticdotventures]

use node v20 or higher. .. i had this problem on cloudflare worker build process set .nvmrc to "20" and solved problem.

So how does bun fix this?

@Borber while Bun already covers a lot from Node's API, there're some cases where it still relys on Node code paths. Like path, fs or certain crypto APIs...
