Formik: Why formik is dependent on lodash and lodash-es?

[latuszek]

❓Question

Why formik is dependent on lodash and lodash-es? Shouldn't it utilize only one of the dependencies?

[ranisalt]

It not only depends on both, it apparently simply does not use -es version.

It's surely better to fix it in Formik, but in the meantime we can use a Webpack alias to drop "lodash-es" from the bundle: https://github.com/GoogleChromeLabs/webpack-libs-optimizations#alias-lodash-es-to-lodash

There is nothing to fix in formik. lodash-es is used by esm bundle. You better to alias commonjs version because webpack wraps each commonjs module with function. So you end with bigger bundle size.

The recommendation is wrong.

[latuszek]

Maybe it would be better to use a single dependency in a way described here.

[TrySound]

Single dependency is used. But different for node and for bundler. All packages should follow same (or just avoid using lodash).
