Javascript bot programming using Gemini API, NodeJS and CryptoCompare - DISCUSSION

I can’t use gemini in germany… any recommendations for other exchanges that work in a simular way so i can follow the course?

[Leo1]

Hi Carlos, i have tried as per your instructions but i am still getting error message require is not defined. Please see my code below

My packages .json

Can you help, please?@thecil

[Leo1]

Bitfinex, the api is a bit more complex but they also have sandbox account.

hey @thecil
i’m having some network issues… is there a way to install yarn from a manually downloaded source code? e.g. from their github
OR
can i use the wget function from my local folder where we’ve been working for these assignments? or is it something that you can only access from another folder?

new problem
(edit: on a mac, btw)
eventually got the yarn to install locally*, but of course when i try yarn add gemini-api, it tells me the command “yarn” is not found… i tried sudo npm install yarn --global, but my user can’t get that access (“Missing write access to /usr/local/lib/node_modules”), and my master password isn’t working there…

by installed locally i mean

MyComputer:TA w filip and ivan users$ npm install yarn

MOST RECENT EDIT:
finally just used npm install gemini-api and got no errors so far…
i’d like to use your credentials @thecil (that i got from here Javascript bot programming using Gemini API, NodeJS and CryptoCompare - DISCUSSION) or ivan’s from the video in order to check that anything there is working and avoid having to go through the entire account setup process with gemini (i try to minimize the number of centralized accounts i use in order to avoid all the risks associated with centralization)
Please LET ME KNOW if that’s not ok! i’ll hold off for a day or two

[B_S]

fyi: “terminal” is the app he’s talkingabout in case you’re still wondering… i realize it’s a bit late, but i happened to be poking around haha

[thecil]

hey @Leo1, hope you are well.

Could you please share an screenshot about the console error that is showed to you?

Also please share your code in the following way so i can copy/paste easily

FAQ - How to post code in the forum

Thanks to @thecil for this guide How to post readable code in the forum You can use the “Preformatted Text” button to encapsulate any kind of code you want to show in your post. The demonstration, below, shows you how, and what the formatted code will look like: function formatText() { let words = "I'm a preformatted text button. Please use me wisely!"; } [image] [preformatted text]

@thecil, would it be worth it to solve some problems in this thread by you guys giving out some keys/credentials and telling people to head over to something like https://npm.runkit.com/gemini-api ? not having to download and install anything from terminal/powershell would certainly be helpful to me, and i don’t think would detract too much from the class, although i don’t know if that fits your guys’ goals…

if you’re not too busy, i’m also wondering what destructured means in this context (what is { getTIcker } literally in this case?):

// The methods are bound properly, so feel free to destructure them:
const { getTicker } = restClient;
getTicker('btcusd')
  .then(data =>
    console.log(`Last trade: $${data.last} / BTC`)
  )

[B_S]

i think i got one of those (on a mac) and it was fixed by adding a “catch line” like so after the .then…:

restClient.newOrder({amount: 10, price: 27000, side:"buy", symbol:"btcusd"})
.then(response => console.log(response))
.catch(console.log);

yeah i know it’s been a while, but just in case…!

[Leonard_Gohlke]

Thanks mate!
I ll have a try.

@thecil

global.fetch = require ("node-fetch");

is there anything wrong with the above code?
if not, why do i get the folllowing?

*****$ node tradebot4TA.js
trader_bot active
internal/modules/cjs/loader.js:1102
      throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);

require() of /******/node_modules/node-fetch/src/index.js from /*****/tradebot4TA.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /*****/node_modules/node-fetch/package.json.

ok NOW knowing that i did not yarn add node-fetch, but used npm i node-fetch… what difference does that make? (i haven’t been able to get yarn working, but npm worked for gemini and cryptocompare up until global.fetch…

[Leo1]

Hi @thecil thanks for coming back to me. I have found where the issue was. Basically in the package.json the type need to be changes to common.js instead of module as well. it is line 17 on my screenshot.
Hope it will help some lost soul in the future

[thecil]

Hey @B_S, hope you are great!

Please take a look to this reply, which is releated to the same issue that you have with the fetch module.

Javascript bot programming using Gemini API, NodeJS and CryptoCompare - DISCUSSION

Perfect, I have managed to run your code properly. I think the issue is on the module node-fetch at the latest version, I just switch the version dependency in your package.json so I force it to download the same version that I have in my old version, and it does the trick. [image] NOTE: please remember to delete your node_modules folder and then change the version on the dependecies and then npm install again. Then I was able to run your script properly [image] @Lehigr2, @PhilD…

733.12 seconds of updating node-fetch… and another 30 of running my new and improved trad-bot… it’s working all right!

[Leedecker425]

Hi, I can’t figure out how to get the npm package over to atom even though I followed the video and went through the correct steps on how to set up the npm package

[B_S]

whoooof, it’s a long road for some of these machine vagaries… this course in particular was subject to more of the “out-of-date” or machine-specific type of issues than the others i’ve tkaen; that said, i’m not sure how to help with this problem (i just tried installing to my local folder, which worked), but two big ones that came up for me were the node-fetch downgrade (just a couple posts above yours here), and yarn not wanting to play nice (so i skipped it and just used npm for the remainder of the course)… also using a vpn or similar might’ve been messing up my connectivity in the first place…

[thecil]

Hey @Leedecker425, hope you are well.

Could you please provide an screenshot about your issue? Which is the process that you are following to use npm?

Carlos Z

[skawal22]

@thecil, I am getting the same type of error. If i understand correctly, you suggested to remove this line from the code:

global.fetch = require('node-fetch');

removing this line i get

referenceerror: fetch is not defined.

Didnt attach snapshots because its pretty similar to @Riki 's error messages

[skawal22]

@thecil, ignore my previous comment. I followed this post and found the solution.

Thanks,
Sk

// Hello bot-mongers

I’m stuck at the “yarn add gemini-api” step in powershell.
all the steps in the “Gemini Yarn Install” video worked fine up to this point.
Further more, I am unable to find the webpage Ivan uses to copy “yarn add gemini-api” from.

edit: resolved. If u encounter this prob too, check out reply #77 in this thread.
