I want to integrate Quasar with FeathersJS using Feathers-Vuex
Feathers-Vuex uses a pattern to:
promise to authenticate from localStorage/cookies
.then( /*start the new Vue() app */ )
I created my app with Quasar CLI 1.0.beta16-ish and looked through /src and couldn't find the main entry point for Quasar. I feel like I'm missing something.
What includes src/store/index.js?
quasar.conf.js includes this comment - where is the main.js
// app boot file (/src/boot)
// --> boot files are part of "main.js"
boot: ["axios"],
Feathers-Vuex includes a Nuxt integration guide that may solve the same problem. These packages are all new to me, and I'm excited to learn them!
Thank you!
The part of main.js is included in quasar app.js that you can find in .quasar folder. The src/store/index.js contains the Vuex Store definition. A "store" is basically a container that holds your application state.
For more detail visit - https://quasar-framework.org/guide/app-vuex-store.html https://quasar-framework.org/guide/app-plugins.html
I ended up with two things:
Adding Feathers-Vuex to my backend.
Adding this "boot file" in my Quasar project
The comments are a bread-crumb trail if I ever have to figure it out again :-)
/*
Context:
For 3rd-party API's, we us /src/boot/axios.js
For our own API's, we use FeathersClient (socket.io & REST)
https://docs.feathersjs.com/guides/basics/clients.html
https://docs.feathersjs.com/api/authentication/client.html#appconfigureauthoptions
Our FeathersClient is in `/src/lib/feathersClient.js`
and imported into `/src/store/index.js`
which is imported by Quasar's build system. /src/quasar.conf.js setting(?)
Feathers-vuex integrates Vuex with FeathersClient:
https://feathers-vuex.feathers-plus.com/auth-module.html
Feathers-Vuex proxies it's authentication/logout actions to FeathersClient
https://github.com/feathers-plus/feathers-vuex/blob/master/src/auth-module/actions.js
The parameters for these actions are here:
https://docs.feathersjs.com/api/authentication/client.html#appauthenticateoptions
In addition to this module, you can use FeathersVuex state in UI from here:
https://feathers-vuex.feathers-plus.com/auth-module.html
This module:
Create a Feathers Auth integration for Vue as a Quasar Boot Module.
// Use case: test if user is authenticated
if (Vue.$auth.currentUser()) { ... }
// Use case: get current user's email
name = Vue.$auth.currentUser("email") || "anonymous"
// Use case: Login
Vue.$auth.login({
strategy: 'local',
email: 'my#email.com',
password: 'my-password'
});
// Use case: Logout
// logs out and sends message
let p = Vue.$auth.logout();
// After logout, go home
p.then(() => {
// User data still in browser
router.push({ name: "home"});
// To clear user data, do a hard refresh/redirect - https://feathers-vuex.feathers-plus.com/common-patterns.html#clearing-data-upon-user-logout
location && location.reload(true)
});
*/
export default ({ app, router, store, Vue }) => {
// Create the API demonstrated above
const auth = {
currentUser(prop) {
let u = store.state.auth.user || false;
if (u && prop) return u[prop];
return u;
},
login(authData, quiet) {
return store
.dispatch("auth/authenticate", authData)
.then(() => {
Vue.prototype.$q.notify({
message: "Welcome back!",
type: "info"
});
})
.catch(err => {
if (!quiet) {
console.log(err);
Vue.prototype.$q.notify({
message: "There was a problem logging you in.",
type: "error"
});
}
});
},
logout(quiet) {
return store.dispatch("auth/logout").then(() => {
if (!quiet)
Vue.prototype.$q.notify({
message: "You've been logged out.",
type: "info"
});
});
},
register(authData) {}
};
// Auth from JWT stored in browser before loading the app. true => suppress token not found error
auth.login("jwt", true);
// Add API to Vue
Vue.prototype.$auth = auth;
// If you would like to play with it in the console, uncomment this line:
// console.log(auth);
// Then, in the console:
/*
temp1.login({
strategy: "local",
email: "feathers#example.com",
password: "secret"
})
*/
// If you haven't created this user, see here:
// https://docs.feathersjs.com/guides/chat/authentication.html
// For this REST api endpoint
/*
curl 'http://localhost:3001/users/' -H 'Content-Type: application/json' --data-binary '{ "email": "feathers#example.com", "password": "secret" }'

I'm using the ipfs-http-client module to interact with IPFS. My problem is that I need the file extension on the link that I generate, and it seems that I can only get it with the wrapWithDirectory flag (-w with the command line). But this flag makes the result empty so far. The documentation on IPFS is only about the command line, and I've only found out a few tutorials about how to do it, but with other tool than JS, or by uploading folders manually. I need to do it from a JS script, from a single file. The motivation is that I want to generate metadata for an NFT, and a metadata field requires to point to a file with a specific extension.
Full detail: I need to add a GLB file on Opensea. GLB are like GLTF, it's a standard for 3D file. Opensea can detect the animation_url field of the metadata of an NFT and render that file. But it needs to end with .glb. Translation, my NFT needs its metadata to look like that:
{
name: <name>,
description: <description>,
image: <image>,
animation_url: 'https://ipfs.io/ipfs/<hash>.glb' // Opensea requires the '.glb' ending.
}
The way I do this so far is as follows:
import { create } from 'ipfs-http-client';
const client = create({
host: 'ipfs.infura.io',
port: 5001,
protocol: 'https',
headers: { authorization },
});
const result = await client.add(file); // {path: '<hash>', cid: CID}
const link = `https://ipfs.io/ipfs/${result.path}` // I can't add an extension here.
In that code, I can put animation_url: link in the metadata object, but OpenSea won't recognize it.
I have tried adding the option mentioned above as well:
const result = await client.add(file, {wrapWithDirectory: true}); // {path: '', cid: CID}
But then result.path is an empty string.
How can I generate a link ending with .glb?
Found out the solution. It indeed involves creating a directory, which is the returned CID, so that we can append the file name with its extension at the end. The result is https://ipfs.io/ipfs/<directory_hash>/<file_name_with_extension>.
So, correcting the code above it gives the following:
import { create } from 'ipfs-http-client';
const client = create({
host: 'ipfs.infura.io',
port: 5001,
protocol: 'https',
headers: { authorization },
});
const content = await file.arrayBuffer(); // The file needs to be a buffer.
const result = await client.add(
{content, path: file.name},
{wrapWithDirectory: true}
);
// result.path is empty, it needs result.cid.toString(),
// and then one can manually append the file name with its extension.
const link = `https://ipfs.io/ipfs/${result.cid.toString()}/${result.name}`;
I'm learning Angular 6 and I have a List shown on my site. Now, i need to give Users of my site the possibility to add entries to that list. There's a form with 4 fields and a submit button, when Submit is clicked, the values should be stored anywhere and all the entries should be shown on the site, permanently, not just in the active session.
How can i achieve this? Do i need to include some sort of database? Or is it possible to append the new dataset to a JSON file?
Thank you in advance
EDIT: This is a training project and will only be available through the Intranet of the Company i work at, so security concerns about missing Captchas or similar things are not a factor
If you are going to use this project for long time and if number of entries is higher and you have alot of users, then you should use some data base. And if there is limited number of users and you need this app temporary then using json file is also good. Using json file will save you from database logics etc if you are not familiar with them
To SAVE some data anywhere you HAVE TO use some kind of database.
Angular is JavaScript framework. It helps to write applications. But it does nothing with server side (except, of course, CLI and other stuff which NodeJS people likes to do).
JSON is not the only way to communicate between browser and the server. But in Angular it's easiest way.
You'll need something on the server (I suppose PHP script) which will receives data from your Angular app and will send back some feedback. In the case with PHP you'd learn how to receive JSON POST ($_POST and $_REQUEST will not work)
What I advise you in terms "how to learn Angular" is go to this step-by-step tutorial https://angular.io/tutorial
Run it twice or three times and you'll understand how works Promises, Observables, communications, templates, services and all other stuff.
It is possible to append the data to the new dataset to the JSON file create a service to read that JSON file using that service so to give you the basics of reading that JSON file
Config.service.ts
#Injectable()
export class ConfigService {
private static _config: any = {}
constructor(private _http: Http) { }
load() {
return new Promise((resolve, reject) => {
this._http.get('../assets/' + 'data.json')
.map(res => res.json())
.subscribe((data) => {
console.log("inside http get of the new service");
console.log(data);
ConfigService._config = data;
resolve(true);
},
(error: any) => {
console.error(error);
return Observable.throw(error.json().error || 'Server error');
});
});
}
// Gets a value of specified property in the configuration file
get(key: any) {
console.log("tell me the base :" + ConfigService._config['BASE_URL']);
return ConfigService._config[key];
}
}
export function ConfigFactory(config: ConfigService) {
return () => config.load();
}
export function init() {
return {
provide: APP_INITIALIZER,
useFactory: ConfigFactory,
deps: [ConfigService],
multi: true
}
}
const ConfigModule = {
init: init
}
export { ConfigModule };
add these lines in your main module
app.module.ts
import { CommonModule } from '#angular/common';
import { ConfigModule, ConfigService } from './config-service';
providers:[
ConfigService,
ConfigModule.init(),
]
Then, you can inject this service on any component or service that wants the data
Also, you have to add an assets folder under your app folder and place the data.json there.
I'm trying to authenticate using github.
I configured properly the callback, successRedirect and failureRedirect.
The successRedirect page is called. In this page I try to call the authenticate function.
client.authenticate({
strategy: 'github'
})
The promise resolve with a token but when I try to access a secured service, it returns an error. Then If I try to retry to access a second time to the service, it works.
Can someone explain me or provide me a working example.
My code:
const hello = client.service('hello');
function getVal(iter) {
console.log("Iter " + iter)
hello.get(1, {}).then((data) => {
console.log('User is logged');
console.dir(data)
}, (error) => {
console.dir(error)
getVal(iter + 1)
})
}
client.authenticate({
strategy: 'github'
}).then((token) => {
console.dir(token)
getVal(0)
}, (error) => console.dir(error));
In the logs I see that the first call to the service fails with an authentication error but not the second while I'm supposed to be logged (because it's in the configured success redirection)
My logs:
Object { accessToken: "eyJhbGciOiJIUzI1NiIsInR5cCI6ImFjY2…" }
Iter 0
{
className: "not-authenticated"
code: 401
……
}
Iter 1
User is logged
{…}
The oAuth2 client usage API shows that instead of calling authenticate you just have to link the user to /auth/github to kick of the oAuth flow:
Login With GitHub
I can't seem to find any documentation on how to actually use the postabck feature. Does it call functions on the server? What does ti do with the pasees value?
%[Button label here](postback:PAYLOAD_HERE) // What is the payload?
The payload is actually whatever you want!
Postback buttons can be used as triggers to your webhook. When a user taps on your postback button, a payload will be sent to your webhook with the following data:
{
"trigger": "postback",
"postbacks":[{
...
"action": {
"_id": "571530ee4fae94c32b78b170",
"type": "postback",
"text": "Read more",
"payload": "YOUR_PAYLOAD_HERE" // <---- your payload!
}
}],
...
}
For complete payload see this reference: http://docs.smooch.io/rest/#webhooks-payload
On your side, you could have automated messages, event scheduling or anything you want.
A simple payload could be TELL_ME_JOKE and on your backend, you could fetch your database for a joke, then send a message through the Smooch API to reply back.
Another payload could be RESERVE_MONDAY. When the user taps that button, your webhook receives RESERVE_MONDAY. Then you could use that value to know what to do next (call into your application to reserve that time slot).
Here's a simple Node.js implementation:
const express = require('express');
const SmoochCore = require('smooch-core');
const smoochApi = new SmoochCore({
keyId: 'some-key',
secret: 'some-secret',
scope: 'app'
});
express.Router().post('/smooch/webhooks', (req, res) => {
const smoochPayload = req.body.postbacks[0].action.payload;
const userId = req.body.appUser._id;
if (smoochPayload === 'TELL_ME_JOKE') {
smoochApi.conversations.sendMessage(userId, {
text: 'A cow walks into a bar...',
role: 'appMaker'
});
} else if (smoochPayload === 'RESERVE_MONDAY') {
CalendarController.reserve(userId, 'monday');
}
res.end();
});
Using the payload also allows you to use different button labels, but keep the same payload (ie. different translations).
Note: it could be anything even JSON if you want!
I hope this can help you!
The payload is what you want your bot to return. I'm not sure if my way of describing it is the best since I'm new at this. Think of it this way - If you have a button labeled %[Yes](postback:YES), then when the user clicks on the button that says yes, it will be just like they typed the word "yes."
I am looking to perform multiple actions upon receiving HTML(or EJS) form content using the POST method. I am using Node express, mongoose & mongoDB. Each of the below POST responses work individually but i am unsure how to proceed in updating multiple databases based on ONE SINGLE form submission.
// insert into passport db
app.post('/signup', passport.authenticate('local-signup',
{
successRedirect : '/index', // redirect to the secure profile section
failureRedirect : '/signup', // redirect back to the signup page if there is an error
failureFlash : true // allow flash messages
}));
//insert into my database here
[the content of in the second function is unimportant as that is working fine and has been stripped down for simplification.]
app.post('/signup', function( req, res )
{
new UserDB(
{
user_id : req.body.content,
first_name : req.body.fname,
}).save( function( err, mySite, count )
{
res.redirect( '/index' );
});
});
I have tried redirecting but the form content is not accessible after the redirect so only the first function stores the data (ie. only 1 database is filled).
How would i run both functions within
app.post('/signup',.....
{
...
});
?
Thanks in advance!
You can do this by making one function the callback of the other. This is easy because each function maintains the same Connect middleware signature, function(req, res, next), where req and res are the request and response objects created and manipulated by the application, and next is the next function to call at the end of the current function's execution.
According to the official documentation, passport.authenticate() is a normal piece of middleware. All you need to do is specify the middleware you want to be called next. Express queues middleware functions in the order in which you pass them into app.post. You can do something like this:
app.post('/signup', passport.authenticate('local-signup', {
failureRedirect : '/signup',
failureFlash : true
}),
function(req, res) {
new UserDB({
user_id : req.body.content,
first_name : req.body.fname,
}).save(function(err, mySite, count) {
res.redirect('/index');
});
});
Middleware is an extremely powerful feature of the Express framework and possibly the single most important one to master. This guide would be a great next step if you want to learn more.
