Conversation
This change is to align with the classic Node.js buildpack which adds `node_modules/.bin` to `PATH` for later buildpack and runtime usage. There are several cases where this doesn't help making installed Node.js module bins available for certain package manager configurations (e.g.; Yarn Pnp, workspace installs, etc.) but, for now, this will work well for a majority of cases. > [!NOTE] > The reason why the layer is named `z_node_module_bins` is due to layers being processed in alphabetical order at runtime (see [this RFC](https://github.com/schneems/rfcs/blob/schneems/explicit-layer-ordering/text/0133-explicit-layer-order.md) for more details). The `z_` prefix ensures that the layer get processed last and the Node.js module bin path is the last one to be prepended to the `PATH`. This effect can be observed in the snapshots.

This change is to align with the classic Node.js buildpack which adds
node_modules/.bintoPATHfor later buildpack and runtime usage.There are several cases where this doesn't help making installed Node.js module bins available for certain package manager configurations (e.g.; Yarn Pnp, workspace installs, etc.) but, for now, this will work well for a majority of cases.
Note
The reason why the layer is named
z_node_module_binsis due to layers being processed in alphabetical order at runtime (see this RFC for more details). Thez_prefix ensures that the layer get processed last and the Node.js module bin path is the last one to be prepended to thePATH. This effect can be observed in the snapshots.W-21259546
