We have released v4.0.0 of the ICP JavaScript SDK libraries . This major release introduces the new unified @icp-sdk/core package, consolidating multiple @dfinity/* packages into a single solution. What’s New The only change in v4.0.0 is the introduction of @icp-sdk/core , which unifies the following…

You can do that, although it’s not recommended. v2 to v3 V3 had some breaking changes compared to v2 (see the v3 upgrading guide ), so you first need to sort them out in your source code. v3 to v4 Upgrading from v3 to v4 should just be a simple, single step. You just have to switch packages and cha…

I attempted to upgrade the code to v4, but I have installed numerous libraries from ic-js, which prevents me from using npx to upgrade. Starting migration to @icp-sdk/core... 📦 Found @dfinity dependencies to migrate: @dfinity/agent@^3.2.2, @dfinity/candid@^3.2.2, @dfinity/identity@^3.2.2, @dfinit…

For now, ic-js packages are still on agent-js v2. Between this week and the next, a release will be made to bump their deps to v3. I would recommend you to wait until then.

Not all hero’s wear capes, hopefully this will finally resolve the dependency hell

Indeed, this was one of the main reasons behind unifying packages under a single, module-based package!

For now, you can write a little script that finds and replaces the @dfinity/* occurrences with their respective @icp-sdk/core/* submodule: #!/bin/bash # Replace @dfinity/* imports with @icp-sdk/core/* in declarations folder find ./declarations -name "*.d.ts" -o -name "*.js" | xargs sed -i '' \ -…

@e274426380 The dfinity/ic-js libraries have been updated to use the v3 version of the dfinity/icp-js-core libraries. This should make them compatible with the v4 version of the dfinity/icp-js-core libraries as well.

Hey! Having typescript issue with this sdk. As per documentation `In your tsconfig.json file, set the moduleResolution to either node16, nodenext, or bundler` However imports fail for `bundler` option, using node16 or nodenext is not really possible in mobile env, as it fails bunch of other impor…

[image] mzibara: However imports fail for bundler option, using node16 or nodenext is not really possible in mobile env, as it fails bunch of other imports. Can you provide the TS error that you get? Could you also provide your tsconfig setup?
