I'm new to firebase, and I'm doing a database for my discord.js bot. I know how to do almost everything, except i don't know how to get all the db data. Let me explain:
My database structure looks like this:
database structure
And i would like that when executing the showconfig command, it shows something like this:
announcementsChannel: "news",
autoRole: "false",
autoRoleName: "none",
// etc...
Is there any way to get every key and its value, and putting it all inside a message?
db.collection("users").get().then((querySnapshot) => {
querySnapshot.forEach((doc) => {
console.log(`${doc.id} => ${doc.data()}`);
});
});

I want to transfer the data into an array and my api response is like this
inside api response there is: locationslist :"[\"Location 2\",\"Location 2\"]"
How to get a clean response in react Js?
And I am also try a JSON.parse() it's give me error
This should do it just fine:
const localtionList = "[\"Location 2\",\"Location 2\"]";
console.log(JSON.parse(localtionList))
You are getting error because you are trying to parse JavaScript object using JSON.parse(). To fix the issue you need to pass JSON string to the JSON.parse() method like following:
const something = {
locationslist :"[\"Location 2\",\"Location 2\"]"
};
// This code will give error
console.log(JSON.parse(something));
// This will work fine because locationslist
// holds a JSON string
console.log(JSON.parse(something.locationslist));

My question is simple how can I pipe type date ?? meanes if the date in MongoDB looks like this :
2021-01-31T23:00:00.000+00:00
and in my case I want it to take this format 2021-01-31 no more
please how can I do it I'm using MEAN stack (MongoDB, Express js, Angular, Node js)
I want to do it without changing it into a string and get a substring is that possible?
Please help
With Angular, You need to use angular datePipe: https://angular.io/api/common/DatePipe
HTML side:
{{ yourDate | date:'yyyy-MM-dd' }}
If you want to convert it typescript side, you need to provide DatePipe in your appModule :
#NgModule({
....
providers:[DatePipe]
....
})
Then you can use it as service in your component:
constructor(datePipe: DatePipe) {}
...
function() {
const date = this.datePipe.transform(yourDate, 'yyyy-MM-dd')
}

I am new to discord.js coding, I have been trying to make a meme generator, any can help me?
You can use npm packages to generate memes.
for this command idea, I will use "random-discord"
First of all , install random-discord by using npm i random-discord random-discord Docs
and create new random-discord app with :
const { Random } = require('random-discord')
const random = new Random
finally, Add this code to your bot main file :
client.on('message', message => {
if(message.content.toLowerCase() === "meme") {
let meme = await random.getMeme()
message.channel.send(meme)
}
})

Looking at the example given here (http://underscorejs.org/#wrap), I don't really understand what wrap is doing ... Even more so, when the function is "wrapped" it feels the parameters have to be set (for example, what about doing hello('john')? Are there other examples available that explains what wrap is all about? What would be a typical use case for it?
Thanks!
C
_.wrap() can accept more parameters in callback function other than the function you have. For example to make your hello('John') example work we need some modification on the example code to be
var hello = function(name) { return "hello: " + name; };
hello = _.wrap(hello, function(func,name) {
return "before, " + func(name) + ", after";
});
hello('John');

i'm using aws-sdk in nodejs, this is the part of the code that delete the files:
var s3_params = {
Bucket: util.getEnvVar('AWS_S3_BUCKET'),
Delete: {Objects: [{Key: document.bucket_path }]}
};
s3.deleteObjects(s3_params, function (err, data) {
if (err) {
res.send(err);
} else {
res.send(data);
}
});
The response that return from amazon look fine, but when i look on the bucket inside the s3 interface the file still exist.
also try to use "deleteObject" method with no success.
Thanks.
The code looks good. Are you sure you are passing a Key of a file that exists? Beware that if you try to delete a Key that does not exist, AWS won't throw an error, check this question.
