Compose and Link Functions
Functions can call other functions. Build small, compose big.
get-weather.ts
export async function main() {
const res = await fetch(
"https://wttr.in/Tokyo"
);
return res.text();
}
weather-to-discord.ts
import fn from "@microfn/fn";
export async function main() {
const weather = await fn.executeFunction(
"david/get-weather"
);
return fn.executeFunction(
"david/send-discord",
{ message: weather }
);
}
send-discord-message.ts
export async function main(input: { channelId: string, content: string }) {
const token = await secret.getRequired("DISCORD_BOT_TOKEN");
const response = await fetch(
`https://discord.com/api/v10/channels/${input.channelId}/messages`,
{
method: "POST",
headers: {
Authorization: `Bot ${token}`,
"Content-Type": "application/json",
},
body: JSON.stringify({ content: input.content }),
},
);
if (!response.ok) {
const data = await response.json().catch(() => ({}));
throw new Error(`Discord error: ${response.status} ${JSON.stringify(data)}`);
