I'm using jovo framework (version 1.0.0) and I'm facing the following problem:
In app.js:
app.setHandler({
'NEW_USER': () => {
this.tell('Hello, I've just installed this skill.');
}
});
I get the following error when a user is new to the skill:
TypeError: this.tell is not a function
Can't I use this.tell in the NEW_USER?
System Environment:
Windows 10 Home
NodeJS: v8.9.1
I really appreciate any help you can provide.

When I test my React Native app that un my firebase config file
const auth = initializeAuth(app, {
persistence: getReactNativePersistence(AsyncStorage),
});
I get the error message: Cannot find module '#firebase/auth/react-native' from 'node_modules/firebase/auth/react-native/dist/index.cjs.js'
The app works fine in runtime, but doesn't seem to work during tests.
Any ideas to what this error could be caused by?
I was having the same issue this morning. Did you get it resolved?
I found that creating a file in the mocks directory called #firebase/auth/react-native.js and exporting a named function getReactNativePersistence resolved the issue (for now) for me. It's just a dummy function at this point, but my tests run.
__mocks__/#firebase/auth/react-native.js
export const getReactNativePersistence = () => {
return;
};
Am getting this error after following the steps mentioned in the nativescript-plugin-firebase readme file.
JS: firebase.init error: TypeError: Cannot read property 'database' of
undefined
https://github.com/EddyVerbruggen/nativescript-plugin-firebase
but i dont really understand nor do i know how to solve that.
the version of the plugin am using is : 6.4.0
with tns 4.1.2
EDIT: init code, from app.js
var firebase = require("nativescript-plugin-firebase");
firebase.init({ persist: true
// Optionally pass in properties for database, authentication and cloud messaging,
// see their respective docs.
}).then(
function (instance) {
console.log("firebase.init done");
},
function (error) {
console.log("firebase.init error: " + error);
}
);
I finally solved it by installing the plugin manually via the CLI (i initially installed it through NativeScript sidekick) apparently they didnt take in count the fact that some plugins may require some user inputs, to do write specific config file (which nativescript-plugin-firebase), so by installing it manually i got to provide the user input needed, it got configured and it worked!
I'm trying to use lambda to restore a table in dynamoDB,
but keep getting this error message.
TypeError: dynamodb.restoreTableFromBackup is not a function
Could anyone tell me how to fix it?Thanks~
http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html#restoreTableFromBackup-property
'use strict';
const AWS = require('aws-sdk');
const dynamodb = new AWS.DynamoDB({apiVersion: '2012-08-10'});
exports.handler = (event, context, callback) => {
const params = {
BackupArn: 'arn:aws:dynamodb:us-east-1/xxxxx',
TargetTableName: 'xxx',
};
dynamodb.restoreTableFromBackup(params, function (err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
};
I ran the code you provided in my own lambda and got the same result.
It seems the AWS SDK that is provided natively in Lambda isn't the latest version, with the restoreTableFromBackup function.
If I do the same test while using the latest available in npm, it seems to work fine.
As a work around, I suggest uploading your lambda as a zip file, and including the the node_modules/aws-sdk along with your code.
This will ensure it uses the latest aws-sdk which includes the restoreTableFromBackup function.
To assist further, I've written a walk through of how to use On-Demand backups / restore and how to schedule these backups.

In my angular-meteor app I'm using mdg:camera. I'm trying to update a field from the callback to show the image. Here's the code snippet:
this.addImageToPost = () => {
MeteorCamera.getPicture({
quality: 50
}, this.$bindToContext((err, data) => {
if (err) {
console.log(err);
return;
}
this.imgDataUrl = data;
}));
};
This has been working great. But now after I finished updating my app to use meteor 1.3 (with all the new updates to angular package and mdg:camera as well) this became broken with a "callback is not a function" error.
If I remove the "this.$bindToContext" part, I get a working code - only obviously it's not reactive.
Any idea what's going on? I wonder if the newest updates broke something...
Any help would be greatly appreciated!
After reviewing the new Mobile features with latest 1.0 version of Meteor, I'm not seeing where I would modify the Cordova code to add custom capabilities. For instance, I want to implement push notifications for my application on both iOS and Android. In both cases I would need to write some native code so that I could get devices registered and accept push notification messages.
Currently, I'm using MeteorRider to accomplish this and it works great. I have 3 separate projects for Meteor, Android and iOS. In the latter 2, I put the native code there necessary to accomplish this. One thing is for certain, you have to update the bootstrap classes in Cordova to allow registrations to work.
In Meteor 1.0, how would I go about accomplishing this with the out-of-the-box mobile feature?
Here's the objective-C code for accepting push notification registration responses that is required in Cordova's AppDelegate:
- (void) application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
NSLog( #"Device token is: %#", deviceToken);
// Convert to string that can be stored in DB
NSString *regId = [[deviceToken description] stringByReplacingOccurrencesOfString:#"<" withString:#""];
regId = [regId stringByReplacingOccurrencesOfString:#">" withString:#""];
regId = [regId stringByReplacingOccurrencesOfString: #" " withString: #""];
[[ApplePushNotificationService sharedInstance] application:application uploadDeviceToken:regId];
}
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
NSLog(#"Failed to get token, error: %#", error);
}
TL;DR : The cordova project is in the .meteor/local/cordova-build subfolder.
The default AppDelegate.m gets created in the .meteor/local/cordova-build/platforms/ios/***YOUR_APP_NAME***/Classes subfolder.
If you add a top-level folder called cordova-build-override to your meteor project, the directory tree that it contains will be added to the .meteor/local/cordova-build folder just before the build and compilation step.
So, put your custom AppDelegate.m in a new folder called cordova-build-override/platforms/ios/***YOUR_APP_NAME***/Classes .
mkdir -p cordova-build-override/platforms/ios/foo/Classes
cp .meteor/local/cordova-build/platforms/ios/foo/Classes/AppDelegate.m cordova-build-override/platforms/ios/foo/Classes
The Meteor-Cordova integration page on the GitHub Meteor wiki is the best place (so far) to find the details of cordova development with meteor.
You put your cordova-specific code in plain javascript. It's best not to modify the native code if at all possible; instead, see if you can write your own cordova plugin and use it from your meteor app. The cordova PushPlugin plugin might do what you're looking for, but if not, you can use it as a reference.
This example below will create a new iOS app that uses a non-meteor cordova plugin, from scratch.
NOTE: This is a bare minimum example. Look at the meteor cordova camera plugin for a full example. The code below is based on that plugin.
# create a meteor app foo
meteor create foo
cd foo
# add the iOS cordova platform
meteor add-platform ios
# create a new meteor package, foo-camera.
# NOTE: You need to substitute your own meteor.com developer ID here
meteor create --package your_meteor_developer_id:foo-camera
Now, edit the packages/your_meteor_developer_id:foo-camera/package.js file to add the following:
// Add the camera cordova plugin at version 0.3.3
Cordova.depends({
'org.apache.cordova.camera': '0.3.3'
});
EDIT 1: This causes the plugin to be downloaded to your cordova plugins folder.
You can refer to a git tarball instead of a version number e.g. :
Cordova.depends({
'com.phonegap.plugins.facebookconnect': 'https://github.com/Wizcorp/phonegap-facebook-plugin/tarball/0e61babb65bc1716b957b6294c7fdef3ce6ace79'
});

While we're at it, limit our code to run only on the client, and export our FooCamera object so it can be used in the rest of our meteor javascript:
Package.onUse(function(api) {
api.versionsFrom('1.0');
api.export('FooCamera');
api.addFiles('your_meteor_developer_id:foo-camera.js','client');
});
Edit 2:
If your cordova plugin needs special configuration, you can define this in your meteor app's
mobile configuration file. It will get copied into
your app's config.xml .
E.g.
// ===== mobile-config.js ======
// Set PhoneGap/Cordova preferences
App.setPreference('SOME_SPECIFIC_PLUGIN_KEY','SOME_SPECIFIC_PLUGIN_VAL');
Your app's config.xml will then eventually result in the following:
<preference name="SOME_SPECIFIC_PLUGIN_KEY" value="SOME_SPECIFIC_PLUGIN_VAL"/>
Next, edit the JavaScript file in your package ( packages/your_meteor_developer_id:foo-camera/your_meteor_developer_id:foo-camera.js ) to expose the cordova functionality in a meteor-like manner. Use the official meteor mobile package examples as a reference.
(the code below is stolen shamelessly from the meteor github repo ) :
FooCamera = {};
FooCamera.getPicture = function (options, callback) {
// if options are not passed
if (! callback) {
callback = options;
options = {};
}
var success = function (data) {
callback(null, "data:image/jpeg;base64," + data);
};
var failure = function (error) {
callback(new Meteor.Error("cordovaError", error));
};
// call the cordova plugin here, and pass the result to our callback.
navigator.camera.getPicture(success, failure,
_.extend(options, {
quality: options.quality || 49,
targetWidth: options.width || 640,
targetHeight: options.height || 480,
destinationType: Camera.DestinationType.DATA_URL
})
);
};
Now, add your new (local) package to your meteor app.
meteor add your_meteor_developer_id:foo-camera
Edit your application's main HTML and JS to use your new meteor package.
In your foo.html , replace the hello template with this:
<template name="hello">
<button>Take a Photo</button>
{{#if photo}}
<div>
<img src={{photo}} />
</div>
{{/if}}
</template>
In your foo.js , replace the button click event handler with this:
Template.hello.helpers({
photo: function () {
return Session.get("photo");
}
});
Template.hello.events({
'click button': function () {
var cameraOptions = {
width: 800,
height: 600
};
FooCamera.getPicture(cameraOptions, function (error, data) {
Session.set("photo", data);
});
}
});
Now, plug your device in, make sure it's on the same network as your computer, and start both the meteor server and the ios app.
meteor run ios-device
# If you want to just use the emulator, use the following instead.
# but of course the camera won't work on the emulator.
#meteor run ios
XCode will open. You may need to set up your certificates and provisioning profiles before running your app (from XCode).
In another terminal, tail the logs:
tail -f .meteor/local/cordova-build/platforms/ios/cordova/console.log
Finally, publish your excellent meteor cordova plugin so that everyone else can use it. Edit package.js as per the meteor docs. Then:
cd packages/your_meteor_developer_id\:foo-camera
meteor publish
