In the best interest of moving wagmi forward and aligning with the future of the web,
@wagmi/core is a pure ESM module by default for a number of reasons:
- Most modern libraries, frameworks & browsers (ie. Node 12+, Next, Vite, Vitest, etc.) already support pure ESM,
- To avoid Dual Package Hazard,
- Native ESM support has been out for a while now (since 2019).
In the rare scenario you cannot get the pure ESM module to work with your environment, you can retreat to the CJS Escape Hatch module. The CJS module is available via the
cjs tag on NPM:
npm i @wagmi/core@cjs
