StrapIO

module for working with socket.io with predefined rules. StrapIO will look at Role permission on each action. StrapIO is looking for all roles which have access to the given contenttype and action type.

UPDATE v2: You need to subscribe first before you receive any data. socket.emit('subscribe', 'article') article is the content-type.

using Strapi v3?

you need to install strapio v2. Version 3 will not work with strapi below 4.

Installation

npm i strapio

src/index.js

bootstrap({strapi}) {
        process.nextTick(() => {
            strapi.StrapIO = (require("strapio"))(strapi);
        });
 },

Configuration socket.io

bootstrap({strapi}) {
        process.nextTick(() => {
            strapi.StrapIO = (require("strapio"))(strapi, {
              path: "/other/path/",
              cors: { origin: "*", methods: ["GET", "POST"] },
            });
        });
 },

Usage

server

api/<content-type>/controllers/<content-type>.js

module.exports = {
  async create(ctx) {
    let entity;
    if (ctx.is("multipart")) {
      const { data, files } = parseMultipartData(ctx);
      entity = await strapi.services.CONTENTTYPE.create(data, { files });
    } else {
      entity = await strapi.services.CONTENTTYPE.create(ctx.request.body);
    }
    strapi.StrapIO.emit(this, "create", entity);

    // or send custom event
    strapi.StrapIO.emitRaw("myroom", "myevent", entity);

    return sanitizeEntity(entity, { model: strapi.models.CONTENTTYPE });
  },

  async update(ctx) {
    const { id } = ctx.params;

    let entity;
    if (ctx.is("multipart")) {
      const { data, files } = parseMultipartData(ctx);
      entity = await strapi.services.CONTENTTYPE.update({ id }, data, {
        files,
      });
    } else {
      entity = await strapi.services.CONTENTTYPE.update(
        { id },
        ctx.request.body
      );
    }

    strapi.StrapIO.emit(this, "update", entity);

    return sanitizeEntity(entity, { model: strapi.models.CONTENTTYPE });
  },
};

Client

const io = require("socket.io-client");

// Handshake required, token will be verified against strapi
const socket = io.connect(API_URL, {
  query: { token },
});

socket.emit("subscribe", "article"); // article is the room which the client joins

socket.on("find", (data) => {
  console.log("article:", data);
  //do something
});
socket.on("update", (data) => {
  // do something
});

  // Handshake required, token will be verified against strapi
  (function () {

      path: "/sockettest/",
      query: {
        token,
      },
    });

    socket.emit("subscribe", "article"); // article is the room which the client joins
    socket.emit("subscribe", "myroom"); // custom room

    socket.on("find", (data) => {
      //do something
    });
    socket.on("update", (data) => {
      // do something
    });

    socket.on("myevent", (data) => {});
  })();
