How to communicate between microservices using event bus? - vue.js

Question

I'm trying to send data from one microservice to another through event bus. But still as a result I'm getting an empty data, I don't get what I'm doing wrong, please help.
Trying to send data:
app.get ('/products', async (req , res) => {
let db = await connect();
let cursor = await db.collection('posts').find({});
let doc = await cursor.toArray();
res.json(doc);
if (doc.insertedCount == 1) {
res.send({
status: 'success',
id: results.insertedId,
});
}
else {
res.send({
status: 'fail',
});
}
axios.get('http://localhost:4205/events', {
type: 'Success',
data: {
_id: mongo.ObjectID(id),
doc,
postId: req.params.id,
}
})
});
Event bus:
app.get('/events', async (req, res) => {
const event = req.body;
res.json(event);
axios.get('http://localhost:4202/events', event)
res.send({status:'OK'})
})
Microservice where I want to fetch the data:
app.get('/events', async (req, res) => {
res.send(req.body)
});

First:
app.get('/products', async (req, res) => {
try {
const db = await connect();
const cursor = await db.collection('posts').find({});
const doc = await cursor.toArray();
/* Below are weird code
res.json(doc);
if (doc.insertedCount == 1) {
res.send({
status: 'success',
id: results.insertedId,
});
} else {
res.send({
status: 'fail',
});
}
*/
axios.post('http://localhost:4205/events', {
type: 'Success',
data: {
id: mongo.ObjectID(id),
doc,
postId: req.params.id,
},
});
return res.status(200).send();
} catch (error) {
// Here catch and do something with errors;
console.log(error);
}
});
Second:
app.post('/events', async (req, res) => {
try {
const event = req.body;
console.log(event);
// What's mean next line ?
// res.json(event);
const response = await axios.post('http://localhost:4202/events', event);
console.log(response);
return res.status(200).json({ status: 'OK' });
} catch (error) {
console.log(error);
}
});
Last
app.post('/events', async (req, res) => {
try {
console.log(req.body);
return res.status(200).json(req.body);
} catch (error) {
console.log(error);
}
});
