I am building a very simple cron job backup system for a friend's firebase app;
I have PHP code, using firebase-php that can communicate with the firebase and the API docs state that adding the'?format=export" parameter will retrieve a .json file. Cool, so far.
My question is this: What path (after the firebase URL) is required?
The API doc appears to state that it should be /.json but it returns a 404 /json/ works on the simulator, but also returns a 404 in testing
(note: looking for a single text file, similar to the "Export json" data dashboard, if possible)
Thanks in advance.
The path defined the portion of the Firebase data tree that is being loaded. That means that you can load /any/possible/string and it will return a value, though that value is likely to be null unless you've written data to that path. Also note that without a defined extension (i.e. .json) you'll be attempting to load Firebase's in-browser graphical debugger.
In short, if you're using the REST API, you'll always want to end your paths in .json, but nothing else is required, i.e. https://<your-firebase>.firebaseio.com/.json is perfectly valid, and would download your entire Firebase. The format=export parameter ensures that any Firebase priority values are preserved in your JSON output, under the key .priority at any node, where they would normally be excluded.

For a client I am building a static website rendered with nextjs and deployed on vercel. Everything on this website is static, so I don't need any database. However, this client wants to use the instagram API to show a gallery of their photos on two of their pages. This is with a custom design, so I can't use any embed code, but to the best of my knowledge I have to use the Instagram basic display API
To the problem at hand: I was wondering if there is some way to store a single variable without creating a whole database for it in vercel. I know I can use Environment Variables, but the problem is that the instagram api needs to change the access token every 2 months. To renew the access token for instagram, I was planning to write a CRON job that runs about every month to update this value.
I was wondering if it is possible to somehow store this single value on the deployed site without creating a database just for this single value. For example, is it somehow possible to change an environment variable from within a serverless function?
Any help in the right direction is appreciated!
Thanks
You go to Vercel: settings-> environment variables -> add your variable. In this variable you can store your Instagram API variable and in the code you use process.env.{variable}
Example:
you defined name of variable as instagramAPI in your local files (next.config.js or .env.local)
module.exports = {
env:{
instagramAPI : 'https://instagramapiexample.com'
},
}
you define instagramAPI (exactly the same name of the variable as in the code) on your vercel settings
In your code (local files) you call process.env.instagramAPI variable to have the value of the string.
Your code works as expected.
!IMPORTANT! if you have some secrets or passwords in your process.env.variables you newer saves it in next.config.js. For this purpose you saves your instagramAPI to .env.local (described in point 1). More info here
This question was previously closed, telling me to "update the question so it focuses on one problem only;" I don't know what the problem is, and if I did, I wouldn't be posting this question. Regardless, I'll make some clarifications here:
I was previously using just the normal Firebase module (the one imported using "npm i firebase"); everything worked perfectly before. The issue has to do with the authentication (as far as I am aware) with the Firebase Admin SDK. I don't understand how I'm supposed to send this to the Heroku build without revealing the service account key JSON file on my GitHub.
As for the GOOGLE_APPLICATION_CREDENTIALS path, is there a way where I don't have to set it every session? The Heroku app restarts once a day, and I would need to somehow automate this entry process (or skip it entirely). That's the way I currently understand it. Here's a quote from a previous answer:
When I set the GOOGLE_APPLICATION_CREDENTIALS path, doesn't this only set it on my local machine?
Environment variables only work on the individual machine and process where they have been set. If you want it set on another machine and process, you will have to arrange for that separately. According to the documentation:
Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the file path of the JSON file that contains your service account key. This variable only applies to your current shell session, so if you open a new session, set the variable again.
My main question here is as follows: "I implemented the Firebase Admin SDK incorrectly. How do I do it the right way?"
Even just posting a link to guides that would help would be appreciated (although I understand this is typically discouraged as links sometimes break).
Original:
Note: this is my first time using the Firebase Admin SDK, so I'm really not sure what I'm doing (although I have used Firebase quite a bit).
Recently, I decided I would go back to one of my older Discord bots and actually authenticate its requests to Firebase properly (I hadn't done this previously as I've never authenticated from a server before and didn't think it was possible). I discovered the Firebase Admin SDK, which sounded perfect for my needs (the bot is being hosted on Heroku, for the record).
I found this guide: https://firebase.google.com/docs/admin/setup, but there's a few things I can't wrap my head around (note that these are purely rhetorical, you don't need to answer them in your answer; I'm just providing them so you can understand my thought process):
When I set the GOOGLE_APPLICATION_CREDENTIALS path, doesn't this only set it on my local machine? I could also try running the export command on the server (using "heroku run" in the CLI), but then the path would be pointing to a file that doesn't exist on the server (since the service account key JSON file is on my local machine). Do I need to set an environment variable in Heroku or something?
How does "admin.credential.applicationDefault()" know how to get the credentials?
I can't find any other guides that make sense.
The way I currently have it setup must be wrong, since reads and writes fail silently.
Firebase setup code:
// Setup Firebase:
const admin = require('firebase-admin');
// Initialize Firebase:
admin.initializeApp({
credential: admin.credential.applicationDefault(),
databaseURL: "https://<APP>.firebaseio.com" // I removed the actual <APP> name to ask this question
});
let database = admin.database();
Things like database.ref("test").set("Hello World!"); don't change the data in the database, and no errors are thrown (I've also tried attaching a .then and a .catch to the end of this; still nothing). This was working before I switched over to the Firebase Admin SDK (I was just using the "firebase" module previously, rather than the "firebase-admin" module that I'm now using). The same goes for reading data.
Any help would be appreciated.
Here was my problem:
I was sending res.status(200) outside of the async firebase call, killing the request before firebase had a chance to finish. Somehow localhost allows this to work properly but when its hosted things go sideways.
so I had this
fireabse.database().ref('parent/foo').set('bar');
res.status(200)
I needed this:
firebase.database().ref('parent/foo').set('bar').then(() => {
res.status(200);
});
I have created a brand new free tier project, cloned Puppeteer Firebase Functions demo repository and only changed the default project name in .firebaserc file.
When I run the simple test or version functions I get the correct result. When I open the .com/screenshot page without any parameter I get correct ("Please provide a URL...") response.
But when I try any url, i.e. .com/screenshot?url=https://en.wikipedia.org/wiki/Google I get Error: net::ERR_NAME_RESOLUTION_FAILED at https://en.wikipedia.org/wiki/Google thrown in response.
I tried looking for any name resolution errors related to Puppeteer but I could not find anything. Could this be a problem of using free tier?
The free Spark payment plan restricts all outgoing connections except those API endpoints that are fully controlled by Google. As a result, I expect that puppeteer would not be able to make any outgoing connections to external web sites.
Hello I am trying to read a module with this code:
(: Entry point - must be a read-only query. :)
xdmp:invoke(
'/path/mydocument.xqy',
(xs:QName('var1'), 'test',
xs:QName('var2'), "response"))
I am new in MarkLogic, I am using groovy and the api to connect to it, but also I saw I can invoke the module with this and indeed I did but it returns me
your query returned an empty sequence
I want to know if I can query xs:QName('var1'), 'test', changing test with a wildcard or how can I get all the information from the file called /path/mydocument.xqy?
I tried to use this:
xdmp:document-get("/path/mydocument.xqy)
but it says the file is not found. Although, if I use invoke I can query it, but I don't know what are the values I have to pass. I was wondering if there is something like sql using %% or something to give me all the data.
To answer the first question: "I am trying to read a module "
IF the module is in the database, then you must query the Modules database in which the module resides.
If the module is in the filesystem then you cannot directly access its source as a document but you can by executing xdmp:filesystem-file()
Simplification:
With the Default configuration of the server and REST client, user placed modules are in the "Modules" database and user placed documents are in the "Documents" database. This means, if you do a GET (read a "Document") with no additional parameters, it will return documents from the "Documents" database. Assuming you are using the default configuration for client and server, this would result in the behavior you are seeing. E.g. your Module code is in the Modules database, doing a GET for it by name will search the Documents database and correctly not find it.
You don't mention, and I don't know, the groovy library being used, but the REST API itself and all implementations of general purpose ML REST client libraries I am familiar with have options for overriding the default database with another. If the groovy library supports that, then specify the "Modules" database for your query and it should return the module document. Note: content-type will be application/text not text/xml.
You can simplify things for testing by bypassing the libraries and simply use a browser and try a URL like this http://yourserver.com:8000/v1/documents?uri=/your/module.xqy&database=Modules
Ref: https://docs.marklogic.com/REST/GET/v1/documents
Making the appropriate changes to the path and server for your use.
If you are still confused, then you should start with the basic MarkLogic tutorials and work through them one by one. You will most likely succeed faster by doing this then jumping straight into coding you don't understand yet.
DETAIL:
Note: The default behaviour is to EXECUTE documents when doing a GET call, using the Modules database. Thus doing a GET of http://yourserver:8000/your/module.xqy will EXECUTE it not return its source.
You will notice the REST API has a uri query parameter. This is EXECUTING the REST API code on /v1/documents which in turn will read the document specified by the uri and database parameters and return it.
I guess I can use:
xdmp:invoke(/pview/get-pview-browse-profiles.xqy,
cts:and-query((
cts:element-value-query(
xs:QName("letter"),"*", "wildcarded"),
cts:element-value-query(
xs:QName("collection"),"*", "wildcarded"))))
although it doesn't return anything
I have users uploading files, and a Cloud Function responding by adding the uploaded file to the database, and planned on using the following path:
/files/{user-id}/{filename}
The reasoning being that if a file gets deleted, i can in the Cloud Function immediately get the reference to the database-reference.
However, i am not allowed to use certain characters in db-paths that are allowed in filenames (most specifically, a dot). How should this be set up, so that for a removed Storage-file I can immediately get the correct Database-path?
You could push() the path under /files/{uid} to create the entry, then orderByValue().equalTo(x) to find the entry later for deletion. This way, you won't have to worry about the contents of the file name.
