[MMM-JaST] Just another Stock Ticker (new: version 2.x)

[justbob]

This module has been missing two things from the start, imho:

1.) Ability to rename “Portfolio:” to custom tag, just like we can set stocks.
2.) An option to add to portfolio cash amount.

Everyone likes seeing MagicMirror, but sometimes when guests come over, the last thing you want somebody from outside to see is that you actually have a portfolio, let alone the size of it.
Without it being seen, one can just say that they like to follow trends and keep things private.
I change the name of Portfolio to some made-up ticker and pretend it’s a ticker for some index, but it’s a drag to mess around with en.json file in translations folder every time there’s an update.

As for cash amount, sometimes there is unspecified amount of cash sitting in investors account. It’s not part of the portfolio per se, but being on investor account, it’s almost as good as being a part of portfolio.

Is there any chance of seeing 1.) and/or 2.) being implemented?

@justbob

Thank you for your feedback and ideas for improvement.

Do I understand your feature requests correctly?

1. You want a way to explicitly change the name of the portfolio to e.g. “my money pot:”?
2. Would you like a way to add a fixed value of money to the calculated portfolio assets consisting of shares?
   portfolioValue = extraMoney + calculatedPortfolioValueBasedOnSpecifiedShares

Technically this is possible.
However, unfortunately I don’t have the time to fulfill new requests at the moment due to other projects.

But I am always happy to receive pull requests or small motivating donations.

Dear fans and users of this module,

unfortunately Yahoo has switched off the Stock API in its previous form. The module is therefore currently unable to retrieve data (an error appears in the log).

The author of the library that Jast uses to retrieve data from Yahoo is working on a solution. At the moment, however, it is unclear whether there will/can be one.

I will monitor the progress of the development and keep you informed.

I am sorry that there is nothing else I can do at the moment but wait and see.

[Jalibu]

Update: The issue was fixed.

Please read the version’s release notes for instructions for updating this module.

@Jalibu Thank you for making the change to resolve the API format modification made by Yahoo. My timing was perfect. I was diagnosing the issue on my mirror when you updated your changes. They are working perfectly. Appreciate it.

I had tried to install MMM-Jast module several times but always get this error:
I run Magic Mirror on Raspberry Pi2B . Is this a problem?

@leonids you need to increase the swap space size

and maybe the heap size

for the heap size in config.js before the
modules:[

add

electronSwitches:{ "js-flags": "--max-old-space-size=8192"},

that will allocate 8 Meg of heap. you can make it bigger…

make sure you increase the swap space

I’ll leave that to a Google search for you

Thanks,
I have tried both of these things and nothing helped :(

@sdetweil
I have doubled swap space and added heap settings in config.js but it did not change anything, Still same crash as before

Maybe 1G RAM is too small for this program?
