Configuring AWS Mobile Hub Project

The starter project gives instructions on how to do this from the command line, but some have reported bugs with awsmobile, so here's how to do it in the browser.

NoSQL Database

Enable.

Create a custom table named tasks. Make it Private.

Accept userId as Partition key.

Add an attribute taskId with type string and make it a Sort key

Add an attribute category with type string.

Add an attribute description with type string.

Add an attribute created with type number.

Create an index DateSorted with userId as Partition key and taskId as Sort key.

User Sign-In

Turn this on.

Set your password requirements.

Hosting and Streaming

Turn this on.

User File Storage

Turn this on.

Configuring S3

From the AWS Console, go to S3.

Select the bucket named <project name>-userfiles-mobilehub-<AWS resource number>

Go to the Permissions tab. Click on CORS Configuration. Paste the following into the editor and save.

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">

    <ExposeHeader>x-amz-id-2</ExposeHeader>
    <AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>

Integrating Changes into App

Go back to the command line for your project.

awsmobile pull

Answer yes, when asked "? sync corresponding contents in backend/ with #current-backend-info/"

Install dependencies

npm install

The following commands are needed due to breaking changes in aws-amplify 0.4.6. They may not be needed in the future.

npm install @types/zen-observable
npm install @types/paho-mqtt

Running the app

Now the app is configured and wired up to the AWS Mobile Hub and AWS services. To run the app in the browser, run

ionic serve

To run the app on device, first add a platform, and then run it:

ionic cordova platform add ios
ionic cordova run ios

Or open the platform-specific project in the relevant IDE:

open platforms/ios/MyApp.xcodeproj

Hosting app on Amazon S3

Since your Ionic app is just a web app, it can be hosted as a static website in an Amazon S3 bucket.

npm run build
awsmobile publish
