I am trying to use @iota/client package.

But on building react application I get this error:

/node_modules/@iota/client/out/lib/Client.js:1:2
1: MZ��!�☺L�!This program cannot be run in DOS mode.
     ^
2: $�uG

error during build:
Error: Unexpected character '�' (Note that you need plugins to import files that are not JavaScript)

  • Can you share your package.json and package-lock.json files? Does it help if you delete node_modules/@iota and run npm install again? Looks like your client.js is an EXE file instead of JavaScript... That does not happen for me. – mihi Oct 01 '23 at 20:50

@iota/client is deprecated. Please use the IOTA SDK.

About your error, the library uses WASM, which you will need to provide when using a bundler. See this guide how to do this for Rollup.
