I'm working on a meteor mobile app that displays information about local places of interest and one of the things that I want to show is the weather in each location. I've currently got my locations stored with latlng coordinates and they're searchable by radius. I'd like to use the openweathermap api to pull in some useful 'current conditions' information so that when a user looks at an entry they can see basic weather data. Ideally I'd like to limit the number of outgoing requests to keep the pages snappy (and API requests down)
I'm wondering if I can create a server collection of weather data that I update regularly, server-side (hourly?) that my clients then query (perhaps using a mongo $near lookup?) - that way all of my data is being handled within meteor, rather than each client going out to grab the latest data from the API. I don't want to have to iterate through all of the locations in my list and do a separate call out to the api for each as I have approx. 400 locations(!). I'm afraid I'm new to API requests (and meteor itself) so apologies if this is a poorly phrased question.
I'm not entirely sure if this is doable, or if it's even the best approach - any advice (and links to any useful code snippets!) would be greatly appreciated!
EDIT / UPDATE!
OK I haven't managed to get this working yet but I some more useful details on the data!
If I make a request to the openweather API I can get data back for all of their locations (which I would like to add/update to a collection). I could then do regular lookup, instead of making a client request straight out to them every time a user looks at a location. The JSON data looks like this:
{
"message":"accurate",
"cod":"200",
"count":50,
"list":[
{
"id":2643076,
"name":"Marazion",
"coord":{
"lon":-5.47505,
"lat":50.125561
},
"main":{
"temp":292.15,
"pressure":1016,
"humidity":68,
"temp_min":292.15,
"temp_max":292.15
},
"dt":1403707800,
"wind":{
"speed":8.7,
"deg":110,
"gust":13.9
},
"sys":{
"country":""
},
"clouds":{
"all":75
},
"weather":[
{
"id":721,
"main":"Haze",
"description":"haze",
"icon":"50d"
}
]
}, ...
Ideally I'd like to build my own local 'weather' collection that I can search using mongo's $near (to keep outbound requests down, and speed up), but I don't know if this will be possible because the format that the data comes back in - I think I'd need to structure my location data like this in order to use a geo search:
"location": {
"type": "Point",
"coordinates": [-5.47505,50.125561]
}
My questions are:
How can I build that collection (I've seen this - could I do something similar and update existing entries in the collection on a regular basis?)
Does it just need to live on the server, or client too?
Do I need to manipulate the data in order to get a geo search to work?
Is this even the right way to approach it??
EDIT/UPDATE2
Is this question too long/much? It feels like it. Maybe I should split it out.
Yes easily possible. Because your question is so large I'll give you a high level explanation of what I think you need to do.
You need to create a collection where you're gonna save the weather data in.
A request worker that requests new data and updates the collection on a set interval. Use something like cron-tick for scheduling the interval.
Requesting data should only happen server side and I can recommend the request npm package for that.
Meteor.publish the weather collection and have the client subscribe to that, with optionally a filter for it's location.
You should now be getting the weather data on your client and should be able to get freaky with it.

I have nextjs app with sentry. I want to add new api route, for example api/status, but I want to exclude it from being sent to sentry as it will clutter logs really fast and use my qouta.
I did a small research and it seems that there is an array of urls you can exclude from being tracked. It's called denyUrls. Read more. I have tried to add my url to this array, but it still tracks this url as part of events:
Sentry.init({
...
denyUrls: [
/api\/status/i,
],
...
});
Am I configuring something wrong or this array is not for the purpose of filtering everts.
If so, what's the best way to filter those? Other option I found which I will try next is beforeSend but it feels a bit overkill to simply exclude url. denyUrls feels like much better fit for what I am trying to achieve
I had the same issue and contacted the support for it. I am directly quoting the support here.
The BeforeSend and DenyUrl are options to filter error events, not transactions. For transaction events, please use the tracesSampler function as described on the page: https://docs.sentry.io/platforms/javascript/guides/nextjs/configuration/sampling/#setting-a-sampling-function.
Here is an example to drop all transactions that match a certain name:
tracesSampler: samplingContext => {
if(samplingContext.transactionContext.name == "GET /api/health"){
return 0.0 // never send transactions with name GET /api/health
}
return 0.2 // sampling for all other transactions
}
Note that you might need to customise the function above to better match your scenario.
I hope it will help you ;)
Have a nice day.
I am trying to make some further adjustments to an address text field. But the problem is that its made with airtable. I want to get the input of that address and use it to get some data from zillow API for the user. How can I do this? I have viewed the source HTML and I only see the airtable script.
This probably went unanswered for being too vague. I'll try to leave some pointers if anyone stumbles upon this in the future.
Are you the host of the WP page? do you have access to the Airtable base in question? Is the "frontend" viewable? Airtable's API is pretty well-documented, simple as it may be. Whatever you need, if it's from a shared view, it can be fetched with a curl request.
Other than that,if the base is public, or shared publicly, and particularly if you need this data at a steady rate or in larger quantities, you'd be better off requesting access and collecting the information with a script from the Scripting app. Since ES6, this is as trivial as doing something like
let query = await base.getTable
(cursor.activeTableId)
.selectRecordsAsync()
let payload, selectAll = query.records.map(rec => rec.name),
selectAll ?
payload = { records: JSON.stringify(selectAll) }
: console.error('something went wrong')
remoteFetchAsync(('your scraping endpoint', payload)=>
//rock'n'roll past this point
})
I've been attempting to log activity on a mobile-like device using the Google Analytics Measurement Protocol. All of these attempts have validated using the validation URL, and I can see activity when I look at the real-time reports on the Analytics website. But when I look at the Home or Overview reports for the day - no activity is shown.
The view is set for "All Mobile App Data".
The POST body looks something like this:
v=1&tid=UA-000000000-1&ds=app&qt=1601&uid=uid-zzzzz&t=screenview&cd=Foo&an=Foo%20App%20Name&aid=com.example.foo&aiid=com.example.foo&av=0.0.1&ua=Mozilla%2F5.0%20(Linux%3B%20Android%207.0%3B%20SM-G930V%20Build%2FNRD90M)%20AppleWebKit%2F537.36%20(KHTML%2C%20like%20Gecko)%20Chrome%2F59.0.3071.125%20Mobile%20Safari%2F537.36
The ua field is just a pre-defined string. I found that if I omitted it, the Real Time monitoring listed the hits as desktop hits, although I was in a Mobile report and the ds field was "app".
Am I missing a field that is required? Is there some reason why it is showing up in the real-time report, but not in a daily report? Is there some other way to diagnose why the data is vanishing, or confirm the data is actually being captured?
When i check the debug endpoint the hit is valid

I cannot use one of the mobile libraries from Firebase - this is not one of the platforms they support. I do not wish to pretend this is a web page - there is no associated hostname or path. I do not wish to use Events since I can't do event Behavior Flow, which is one of the things I'm interested in seeing.
I'm aware that it can sometimes take "a day or so" for results to first appear. The site was setup over five days ago at this point, and has received data during that time.
Good thought about the anti-spam setting, however the setting appears to be correct:
I've also tried using GET instead of POST - no change, it still shows the hit in real-time, but then it vanishes.
However, I know that it can record hits permanently. There were two hits from a spammer in Russia that have shown up in the daily report (I wasn't there to see it show up in real-time). I don't know what they did, but would love to find out since it might help figure out how I can add a record.
In the real-time reports, it correctly points out the data center all the hits are coming from. Perhaps that is filtering it out somewhere out of my control?
Try adding Cid I know it says this is an optional parameter but for mobile accounts I belive it may be required.
Client ID
Optional.
This field is required if User ID (uid) is not specified in the request. This anonymously identifies a particular user, device, or browser instance. For the web, this is generally stored as a first-party cookie with a two-year expiration. For mobile apps, this is randomly generated for each particular instance of an application install. The value of this field should be a random UUID (version 4) as described in http://www.ietf.org/rfc/rfc4122.txt.
Example value: 35009a79-1a05-49d7-b876-2b884d0f825b
Although this says it needs to be a UUIDv4, it does work with other UUIDs (I've tested it with a v5, which is a hash against the value used for the uid parameter).
Whenever I encounter code snippets on the web, I see something like
Meteor.subscribe('posts', 'bob-smith');
The client can then display all posts of "bob-smith".
The subscription returns several documents.
What I need, in contrast, is a single-document subscription in order to show an article's body field. I would like to filter by (article) id:
Meteor.subscribe('articles', articleId);
But I got suspicious when I searched the web for similar examples: I cannot find even one single-document subscription example.
What is the reason for that? Why does nobody use single-document subscriptions?
Oh but people do!
This is not against any best practice that I know of.
For example, here is a code sample from the github repository of Telescope where you can see a publication for retrieving a single user based on his or her id.
Here is another one for retrieving a single post, and here is the subscription for it.
It is actually sane to subscribe only to the data that you need at a given moment in your app. If you are writing a single post page, you should make a single post publication/subscription for it, such as:
Meteor.publish('singleArticle', function (articleId) {
return Articles.find({_id: articleId});
});
// Then, from an iron-router route for example:
Meteor.subscribe('singleArticle', this.params.articleId);
A common pattern that uses a single document subscription is a parameterized route, ex: /posts/:_id - you'll see these in many iron:router answers here.
I want to build a realtime quiz game which randomly matches two players (according to their winning rate if they are logged in). I've read through the book Discover Meteor and have a basic understanding of the framework, but I just have no idea of how to implement the matching part. Anyone know how to do that?
if you want to match users who have scores close to each other, you can do something like this : mongodb - Find document with closest integer value
The Meteor code for those Mongo queries is very similar, but there are some subtle differences that are kind of tricky. In Meteor, it would look something like this :
SP // "selected player" = the User you want to match someone up with
var score = SP.score; // selected player's score
var queryLow = {score: {$lte:score},_id:{$ne:SP._id}};
var queryHigh = {score:{$gte:score},_id:{$ne:SP._id}};
// "L" is the player with the closest lower score
var L=Players.findOne(queryLow,{sort:{score:-1},limit:1});
// "H" is the player with the closest higher score
var H=Players.findOne(queryHigh,{sort:{score:1},limit:1});
so, now you have references to the players with scores right above and right below the 'selected player'. In terms of making it random, perhaps start with a simple algorithm like "match me with the next available player who's score is closest" , then if it's too predictable and boring you can throw some randomness into the algorithm.
you can view the above Meteor code working live here http://meteorpad.com/pad/4umMP4iY8AkB9ct2d/ClosestScore
and you can Fork it and mess about with the queries to see how it works.
good luck! Meteor is great, I really like it.
If you add the package peppelg:random-opponent-matcher to your application, you can match together opponents like this:
On the server, you need to have an instance of RandomOpponentMatcher like this:
new RandomOpponentMatcher('my-matcher', {name: 'fifo'}, function(user1, user2){
// Create the match/game they should play.
})
The function you pass to RandomOpponentMatcher will get called when two users been matched to play against each other. In it, you'll probably want to create the match the users should play against each other (this package does only match opponents together, it does not contain any functionality for playing games/matches).
On the client, you need to create an instance of RandomOpponentMatcher as well, but you only pass the name to it (the same name as you used on the server):
myMatcher = new RandomOpponentMatcher('my-matcher')
Then when the users is logged in and which to be matched with a random opponent, all you need to do is to call the add method. For example:
<template name="myTemplate">
<button class="clickMatchesWithOpponent">Match me with someone!</button>
</template>
Template.myTemplate.events({
'click .clickMatchesWithOpponent': function(event, template){
myMatcher.add()
}
})
When two different logged in users has clicked on the button, the function you passed to RandomOpponentMatcher on the server will get called.
One implementation might be as follows:
A user somehow triggers a 'looking for game' event that sets an attribute on user.profile.lookingForGame to true. The event then makes a call to a server side Meteor method which queries for all other online users looking for games.
From there you it really depends on how you want to handle users once they 'match'.
To determine all online users, try using the User Status package:
https://github.com/mizzao/meteor-user-status
Once added, any online user will have an attribute in the profile object of 'online'. You can use this to query for all online users.
