# formio
Needs npm version 20. Version 18 is current version in Debian stable (bookworm).


So, install upstream npm...
```
# Remove existing debian version
sudo apt purge --autoremove nodejs npm

# Install upstream version
curl -fsSL https://deb.nodesource.com/setup_22.x -o nodesource_setup.sh
sudo -E bash nodesource_setup.sh
sudo apt install nodejs

# Check it is ok
node -v
```

Now install formio...

```
git clone https://github.com/formio/formio
cd formio/
git checkout v4.2.2
npm install # FTBFS, stable and HEAD
# run thing
node server
# Then set up proxy.
```
