npm ci command not working. When I'm installing the cat tracker web application

[kirit]

Hey, I'm trying to install the cat tracker application. When I'm executing the npm ci command. It is prompting the following error

ubuntu@ip-172-31-25-55:~/aws/nrf-asset-tracker-firmware-aws/cat-tracker-web-app$ npm ci
npm ERR! fsevents not accessible from jest-haste-map

npm ERR! A complete log of this run can be found in:
npm ERR! /home/ubuntu/.npm/_logs/2021-05-29T15_17_05_201Z-debug.log

Can anyone help me in solving this.

Which version of Node.js and NPM do you have?

After upgrading to NPM v7, it is still in the same place:

Can you explain what "implement the CAT Tracker" means? What do you want to implement?

In the link https://nordicsemiconductor.github.io/asset-tracker-cloud-docs/saga/docs/aws/Customization/Index.html#aws-customization. There are two ways to customize the nRF Asset Tracker. The video shows to modify the data using heart rate sensor data

Markus Tacker (he/him) said:

Where can I edit the changes in the code to modify/edit.

If I want to change the display, let's say, I want to add the Calendar range in the display. Where can I make the changes. Like source code?

[Markus Tacker (he/him)]

You would modify the Web Application: github.com/.../asset-tracker-cloud-app-js

I just spent some time on the provided link.  I understood

I'll explain in a detailed way, What I'm trying to do

so far, I was working on the server(Ubuntu CLI ) installed on the windows

Can I Install the Visual Studio and clone the project and start editing the code?

Once I'm working on it, How can I test it during the development process?

Yes.

Copy the `.env.local` you have created on the server to your local machine and run `npm start`, this will launch the development server of the web app.

[kirit]

Perfect, I'd start working on it. 

I'll ask you one thing, All these days I was also parallelly working on the AWS CloudWatchLogs and the Lambda. I'm trying to store the data in the database. Once it is stored, I wanted to build an application like a dashboard view, Calendar view. 

Now, By looking at the CAT Tracker application, Can I achieve all these? like having a dashboard view, some data displaying. For reference, I have just attached a screenshot of it. 

Can you please let me know?

[Markus Tacker (he/him)]

Yes, the modification provides an example for adding on sensor, but you can totally modify the web application to your needs, if you like.

[kirit]

Perfect, Thanks.

I was working on modifying the code as per the dashboard. Once it is done, I'll try to test the code. Let you know about any updates.

[Markus Tacker (he/him)]

Alright, would you mind accepting a solution for your original problem until then?

[kirit]

Sure

[kirit]

Markus,

I have a question. How do I connect data which I'm fetching from the nRF Asset tracker to the CAT Tracker. In order to see in the application.

Is there any way to connect it?

Can you please let me know?
