Last active February 2, 2024 15:59
JS script that encodes import migrations from Wasp 0.11 to 0.12
const util = require('util');
// `same` means that new export is same as old one. Same name, also type, also user defined.
// The only thing that we impliclty assume will change even for `same` is that new exports are always
// considered to be named exports, even if original one was default.
const same = Symbol("SAME")
const importMappings = [
[["@wasp/config.js", dflt("config")],
["wasp/server", same]

[Wasp] [GPT Web App Generator] Example of plan generation GPT prompt
Wasp is a full-stack web app framework that uses React (for client), NodeJS and Prisma (for server).
High-level of the app is described in main.wasp file (which is written in special Wasp DSL), details in JS/JSX files.
Wasp DSL (used in main.wasp) reminds a bit of JSON, and doesn't use single quotes for strings, only double quotes. Examples will follow.
Important Wasp features:
- Routes and Pages: client side, Pages are written in React.
- Queries and Actions: RPC, called from client, execute on server (nodejs).
Queries are for fetching and should not do any mutations, Actions are for mutations.
- Entities: central data models, defined via PSL (Prisma schema language), manipulated via Prisma.
Typical flow: Routes point to Pages, Pages call Queries and Actions, Queries and Actions work with Entities.

Script that uses NetworkManager to disconnect wifi card when wifi dongle connects and to reconnect it when wifi dongle disconnects.
#!/usr/bin/env bash
# This script should be positioned in /etc/NetworkManager/dispatcher.d/
# This script disconnects wifi card when wifi dongle connects and reconnects wifi card when
# wifi dongle disconnects. That way, when dongle is connected, we are sure it is being used instead of
# wifi card being used, and it all happens automatically.
