roomba | A handy Ruby library for the Roomba Serial Command Interface | Wrapper library

I am attempting to share state between two components I have made. Based on my research I believe I will need to lift state up to an ancestor component and then trickle that state down to the other components. For reference, I have added a file uploader that will receive a json file, then I will have a logic file loop through json and then that data will be rendered into a table with the new values.

I am confused on how to share the state between these components and appreciate any critique.

FileUploader.js

This program adds table row for each client and inside that table row, a td for every value of the client (like name, ip, value, etc.). These values and client are set in a key/value object or dictionary called clientel.

I've set the program as follows:

In my years specifying and designing REST APIs, I'm increasingly finding that its very similar to designing a website where the user's journey and the actions and links are story-boarded and critical to the UX.

With my API designs currently, I return links in items and at the bottom of resources. They perform actions, mutate state or bring back other resources.

But its as if each link opens in a new tab; the client explores down a new route and their next options may narrow as they go.

If this were a website, it wouldn't necessarily be a good design. The user would have to either open links in new tabs or back-up the stack all the time to get things done.

Good sites are forward only, or indeed have a way to indicate a branch off the main flow, i.e. links automatically opening in new windows (via anchor tag target).

So should a good REST API be designed as if the client discards the current resource and advances to the next and is always advancing forward?

Or do we assume the client is building a map as it goes, like um a Roomba exploring our living room?

The thing with the map concept is that the knowledge that one should return to a previous resource, of the many it might know about, is in a sentient human, a guess. Computers are incapable of guessing and so its need programming, and this implies out-of-band static documentation and breaks REST.

I see this bug in console:

[Vue warn]: Property or method "product" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

My template id="productDetail" not receive the property "product" of the template id="product" I don't know how I can push this, please see my cod.

I'm trying to controll my Roomba vacuum cleaner by a RaspberryPi. But still having some problems.

I need to send a special command to the serial interface to start the vacuum cleaner. If I do this in the Bash it works fine:

I'm programming a part of a Web application in which I replace words from a text. I used the Replace function, but I replaced text that I do not want (below put an example). Now I have implemented a function that by splitting the text into words, but when I want to replace two contiguous words in the text. Obviously, it doesn't work.

The first option:

Use R.view dinamicly ...

I'm trying to use Pygame and Python 2.7 to control a Roomba connected to a Raspberry Pi. I'm connected to the Pi through Putty and controlling it through the Putty console. The problem I'm having is that I can't get a Pygame display to show, and Pygame keyboard input only works when the Pygame screen has focus. There's just no window opened when the code runs and Putty's console just sits there. Is there a way to open the Pygame window this way?

I have working code that doesn't use Pygame, but it uses a getch for input so you can only toggle movement through incoming characters, you can't get it to stop moving when you stop holding down the key.

Here is my basic code where I'm just trying to get Pygame to do ANYTHING when I press a key:
