I had some code working fine for a REST endpoint in which a message was:
This was the code:
// POST single message
app.post('/message', (req, res) => {
const url = req.body.properties.url
const image = req.body.properties.image
const extraField = req.body.properties.extraField
db.message.create({
url: url,
image: image,
})
.then(() => myProcess(extraField, 'stepA'))
.then(newMessage => res.json(newMessage))
.then(() => myProcess(extraField, 'stepB'))
})
Now I am trying to have the same using feathersjs, but I do not know how to do 2, 3, 4 exactly.
I have now an AFTER hook for the create method of the message service:
module.exports = function (options = {}) { // eslint-disable-line no-unused-vars
return function processNewMessage (hook) {
const { extraField } = hook.data.properties
Promise.resolve(myProcess(extraField, 'stepA'))
.then( <<NO-IDEA>> ) // Send RESPONSE!!
.then(() => myProcess(extraField, 'stepB'))
return Promise.resolve(hook);
};
};
So my question boils down to: How can I send the response and subsequently trigger 'myProcess stepB' using feathersjs?
Althoug this is 'legacy', I think it might still be relevant.
It is answered in the FAQ of feathersjs! How to do processing after sending the response to the user:
It depends on the promise that you return in your hook. Here's an example of a hook that sends an email, but doesn't wait for a success message.
function (hook) {
// Send an email by calling to the email service.
hook.app.service('emails').create({
to: '[email protected]',
body: 'You are so great!'
});
// Send a message to some logging service.
hook.app.service('logging').create(hook.data);
// Return a resolved promise to immediately move to the next hook
// and not wait for the two previous promises to resolve.
return Promise.resolve(hook);
}
