Here's an example: // // schema.ts import { defineSchema, defineTable } from "convex/server"; import { v } from "convex/values"; // Define a messages table with two indexes. export default defineSchema({ messages: defineTable({ channel: v.id("channels"), body: v.string(), user: v.id("users"), }) .index("by_channel", ["channel"]) .index("by_channel_user", ["channel", "user"]), }); // And use an index like this (note the syntax is different than filter): // const messages = await ctx.db .query("messages") .withIndex("by_channel", (q) => q .eq("channel", channel) .gt("_creationTime", Date.now() - 2 * 60000) .lt("_creationTime", Date.now() - 60000), ) .collect(); // ### Mutation // import { mutation } from "./_generated/server"; import { v } from "convex/values"; export const createTask = mutation({ args: { text: v.string() }, handler: async (ctx, args) => { const newTaskId = await ctx.db.insert("tasks", { text: args.text }); return newTaskId; } }); // ### Action // import { action } from "./_generated/server"; import { internal } from "./_generated/api"; import { v } from "convex/values"; export const sendGif = action({ args: { queryString: v.string(), author: v.string() }, handler: async (ctx, { queryString, author }) => { const data = await fetch(giphyUrl(queryString)); const json = await data.json(); if (!data.ok) { throw new Error("Giphy error: " + JSON.stringify(json)); } const gifEmbedUrl = json.data.embed_url; await ctx.runMutation(internal.messages.sendGifMessage, { body: gifEmbedUrl, author }); } }); // ### HTTP Router // import { httpRouter } from "convex/server"; const http = httpRouter(); http.route({ path: "/postMessage", method: "POST", handler: postMessage, }); http.route({ pathPrefix: "/getAuthorMessages/", method: "GET", handler: getByAuthorPathSuffix, }); export default http; // ### Scheduled Jobs // import { cronJobs } f
