I just tried to do a hello world Polars DataFrame Dioxus app and it turns out you cannot add Polars as a dependency because of some crossterm dependency bother 😦

Some crates have specific features you need to disable/enable for wasm compatability

Doesnt seem like this one needed any wasm specific ones https://github.com/brutusyhy/polars-explorer/blob/main/polars-explorer/polars-playground/Cargo.toml

#

maybe not wasm though? not sure

#

this one has polars as a transitive dep I think https://github.com/space-operator/flow-backend/blob/main/Cargo.toml

GitHub

#

and another dep has wasm in the name, and it’s a web app (it uses polars dataframes to store state in a visual programming web app)

#

(I may well be wrong though just going off metadata!)

try running cargo tree --features web

#

Or just cargo tree if you are not using fullstack

this file mentions both wasm and polars 👀 https://github.com/space-operator/flow-backend/blob/5228a280492134c7ed9b9c103fb14d3e97f376ad/crates/db/src/connection/conn_impl.rs#L13
