Wow, easily the best video education series I've ever watched. Production quality through the roof and presenter is clearly knowledgable and able to communicate in a fun and direct way. Thank You!
The whole series is great! I'm glad you aren't afraid of lengthy videos. The short videos on the channel are good too, but intermediate or more experienced developers want more details. Please keep this up! Also, I feel I laughed more than I should at the "moist" joke :)
Thank you for using a realistic use case like the restaurant app, with some decently complex data, instead of just a "to do app" like every other tutorial out there hah
I dunno what kinda docs you're taking about, but when I spent hours each night struggling to figure out these rules (which I eventually figured out), you answers all my questions in a single 20 min video.
Love the video! Thanks a lot for clear instructions. They have helped me a lot to improve my app!! It's nice to watch which gives an honest approach to the content.
So happy with this video. It really goes into proper depth and will definitely help me secure everything properly! The local emulator definitely deserves another episode though (or maybe an example on git?), as the documentation is quite hard to comprehend fully.
Love your entire series. Would love to see a video on perhaps the best ways to combine all the services together. For example in my current app, we are using realtime database, firestore, firebase authentication, storage and now cloud messaging. With so many products one could see how confusing the entire product ecosystem is...
So nice with a high-quality tutorial series where the presenter is SO good that he doesn't need to beg the viewer to subscribe; we'll do it anyway! And share! Can't wait for the next instalment.
Security Rules, like the noun, but also Security Rules! like the verb... All I know is Database Robin Williams Rules! Seriously thank you for making learning a new language much less intimidating
Great video, great episode: this answered a lot of questions I had regarding security for which I am grateful! I still have one concern regarding security due to the schemaless nature of the database. How can I prevent malicious users from spamming my database by writing data to 'fields' I haven't defined? Because from what I understand, anybody with 'write' access to a certain documents can make a function that writes random key:value pairs to the database and run it from a console. Is is possible to write a function that prevents all keys that aren't defined by me 'the programmer' to be written to the database?
When you have a "roles" map of uid => role, how can you validate to ensure only the owner can add/remove editors, but an editor can remove themselves from the map?
How do you handle when people put random irrelevant data in a document? Is there a way to whitelist which fields are allowed on a document? This could be a security problem if they predict a field that we would add later.
how to allow only some specific internal ip addresses from login into my firebase auth login we app?? please provide me some tips it is turning like a nightmare.
While running the Firestore Rules simulator, request.token seems to be null. And if at all we provide it using Custom Auth Provider, we need to provide "super_admin" it at the "token" level, which is not the case with actual real world situation, as the custom claim is in "customClaims" property of "token" property. TL;DR: With simulation -> "token":{ "super_admin":true } With real case -> "token":{ "customClaims":{ "super_admin":true } }
What if technically someone retrieved information from my app and created his own with the same credentials? He can send to my database the same requests as I do, e.g. send message. I am really confused by it because my project information is public on my website.
Is it true that using sub-collections basically is a kind of extra security? For example, you know that users can only get a sub-collection that belongs to a specific parent id, so unless they know all the parent ids and loop over that, there is no way they can just get a list of all the item in a sub-collection.
I don't know if something has changed at the moment, but it continues to appear in the documentation that the first thing we must put is "rules_version = '2';"; the truth is that it is the first error and it does not allow publishing only by placing that in the rules
if I choose to store my users info using the firebase auth user profile and use the user.diplayName field to store username, and on a Firestore collection('reviews') I have reference to the username. Say when I want to update a user's username (user.displayName), I also need to go and update all duplicated data on the reviews collection. My question is can I make a batch job that consists of a auth.updateProfile and a firestore.docRef.update?
I really like the idea of all these videos, but because I’m a bit of a noob developer, I have a hard time picturing the use cases in real apps. What has always helped is having super basic apps using these cases and watching what happens instead of just discussing what would happen.
Even though it's possible to create Security Rules on each document-attribute, is it possible for a client to add new fields in the update? I can't help but thinking about having all updates/create go theough a Cloud Function first to make more fine-grained validation.
is this any better or worse than using a node.js backend? It seems like a LOT of little rules to write when node.js would make it simpler or would it not?
Lets say i have school. teacher wants to create collection in document for specific students, and few documents for all students in calss . how can i model this ?? I cant assign roles at such granular control
Hi Guys. I implement Firestore within my Backend with Express and have all types of validations against Client side requests. Do i really still need to implement those rules ?
Commonly a large company would have front AND backend devs working on a project. (assuming a 'traditional' server backend is involved). But with Firestore, is this still the case?... for example, with Firebase (and cloud functions, security rules, etc.) typically would this mostly still be done by a backend developer? Or with Firebase is the intent for the front end devs to do this themselves (and thus essentially be full stack)?
Is Cloud Firestore a good selection for a bank account? Can it be safe and reliable to save people's money which is a number to the Cloud Firestore? My concern is reliability and security. Any suggestions?
hi sir, thanx for making this video. but i have some error i am facing right now. error is: Listen for Query(users/-M9hU8UJtjjJws3-_UYE) failed: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}. And query : future: Firestore.instance.collection("users").document(widget.profileID).get(), builder: (context, snapshot) . how to fix?
You mentioned leaking private data because you can only get a whole document, and so separating into a "private" document with security rule is needed. (e.g. you should not store user's sensitive data in the same document as public data) However when I look at REST API it looks like getting a partial document is supported by DocumentMask. firebase.google.com/docs/firestore/reference/rest/v1beta1/projects.databases.documents/get Is it just updated?
From my understanding, if your client is following the exact code of your app, this is correct, there's nothing to worry about. But let's pretend for a moment that the client is a malicious user. If all the private fields are grouped with the public fields, you can't have separate security rules for the fields. And thus, that malicious user who is able to request data by pretending to be sent from your app would get private data - something that you wouldn't want.
How can I make a collection of users with their email & displayName searchable, so you can search for your friend via email or displayName, but disallow someone from getting all these user documents with the email addresses and displayNames inside?
How can we stop users adding new properties for objects? E.g. I can validate the name and dob fields, but how do I stop them adding 50 new fields on an update for example?
It would be great if you showed the structure inside the firebase dashboard as well... I can't get shit to work... I assume reviews are a subcollection of a first-level document the first level documents all represent a restaurant, right?... and the 'score' is a field inside the subcollections documents? I can't get nothing to show at all.. even if I just check request.resource.data.score is number.... ive tried adding score as a number and put in 3 in all places where I can make a field, I even only have 1 main document, and 1 document in the sub-collection, so a total of 2 places where I have put in 3 as a number with a key as score ... but yet I'm denied access... The only thing that works for me is to check if the user is logged in... then I can access it all, no other rules work for me...
When I try to aply rules I get this error: No se han podido guardar las reglas: Línea 1: Parse error. Like this: service cloud.firestore { match /databases/{database}/documents { match /{document=**} { allow read, write: if false; } } }
It says that the video will cover a case where access will be based on some other data in some other collection but then never covers this part. "Some other data located in some other part of your db"
Hi brother can u help me pls. I have this security rules for an ecommerce site but why is it that the products are not showing unless I do allow access top the shallowest match path. This line below, knowing if I allow read access to this line then everyone can read all my documents even those I want to set private. match /{document=**} { allow read if false; // I have to set this to true before all products for selling by all users are displayed in the dashboards of any user. So I cannot do selective securty if I do set it to true since everything is allowed to be read. rules_version = '2'; service cloud.firestore {
match /databases/{database}/documents { match /{document=**} { allow read,create,update,delete: if false;
match /users/{uid}{ allow read; allow update:if request.auth.uid == uid;
match /users/{uid}/products { allow read; allow create: if request.auth.uid != null;

Never able to un-see.
I had the exact same thought straight away lmao. This guy is awesome

Wow, easily the best video education series I've ever watched. Production quality through the roof and presenter is clearly knowledgable and able to communicate in a fun and direct way. Thank You!
Who else noticed that little thread on his right shoulder?! 😁 By the way, a great video! 👍👍
Omg now I can't watch the video
I went directly to the comments to see if I were alone noticing it haha (25s passed so far...)
That's the only reason I scrolled down to see the comments
that thread broke the security rules and listening the video!!
how could you NOT, like the thumb bandage one...
The whole series is great! I'm glad you aren't afraid of lengthy videos. The short videos on the channel are good too, but intermediate or more experienced developers want more details. Please keep this up!
Also, I feel I laughed more than I should at the "moist" joke :)
To be honest, I never realized how 22 minutes passed, like in a snap
Tod always provide a great perspective to look at thing, and create product that is easier for us developer to use
Looking forward at early 2019 for Todd's video on #7- Hey we updated Firestore to support Geoqueries, collection group queries,OR queries. 😁
Thank you for using a realistic use case like the restaurant app, with some decently complex data, instead of just a "to do app" like every other tutorial out there hah
Glad it was helpful!

Just brilliant - so clear and simply explained - thank you!!!!
Best tutorial I have seen so far for learning the security rules :)
What an awesome video, and now I've seen there's an entire series from this guy. explained it perfectly for my ape brain. Thank you!
Finally a video that explains this. Thanks, you helped a lot 😁
Super awesome video thanks for making these and going into some detail!
Best videos series of this channel, as a developer I love it!
This is a great series. Please do a episode all about pagination.
Thanks Todd, super useful and relevant to my development efforts.
Excellent video, with a strong use case !
I love your explanations mate!
Great Series, the string cut the string.
Wow this is explained very well, nice vid
Your videos are a delight! Thank you :D
Glad you like them!

Very nicely presented and explained. 👍
Very useful tutorial! Thanks!
Best tutorials for Firebase.
this guy is awesome! I've become a fan
Club Databass 😂
Awesome video BTW, I learned a lot.
I like this guy. He's like my next-door uncle who always is funny and nice to people.
Man i like ur vids, always .
Great video! Keep it up!

ohhh thanks so much.. i had two days trying to understand ... thank you.
Super super useful!
This guy cracks me up
Amazing! But, where did you get that sick sticker for the laptop? 😍
this is great!!
This genuinely is one of the more enjoyable "tooling how to" videos that I've seen. Great work Todd and Firebase team!
6:54 best thing i heard all day
Did the example for matching google.com contain a bug because it also matches something@totallynotgoogle.com ?
When you have a "roles" map of uid => role, how can you validate to ensure only the owner can add/remove editors, but an editor can remove themselves from the map?
Super super helpful
haha, that IAM joke was really nice
How do i navigate to two worded collections like ‘user record’? ex: match/ user record/{urId}
Thank you very much.
Nice Videos!
It'd be great if Summary of rules/points can be given in description section.
How do you handle when people put random irrelevant data in a document? Is there a way to whitelist which fields are allowed on a document? This could be a security problem if they predict a field that we would add later.
how to allow only some specific internal ip addresses from login into my firebase auth login we app?? please provide me some tips it is turning like a nightmare.
really helpful thankssssssss
great tutorial. thank.

Normally, I would hate these corny jokes. But I love these.

If I write thorough security rules within Firestore, can I eliminate them from the client-side code entirely or should I have them in both places?
a biiiiiiiiiiiiiiig LIKEEEEE, thanks genius!!
Awesome video +++++ 😃
Happy to hear you enjoyed the video, Mohamed! Don't forget to check out the links in the description for more tips and tutorials 👍
If you access to a document field from a security rule, does it count as a read? 💸
I really like the idea of all these videos, but because I’m a bit of a noob developer, I have a hard time picturing the use cases in real apps. What has always helped is having super basic apps using these cases and watching what happens instead of just discussing what would happen.

I have a question when we use the get() method at 16:50, does that get call count to my readers in firestore?
yes
Finally an emoji in the title!
is this any better or worse than using a node.js backend? It seems like a LOT of little rules to write when node.js would make it simpler or would it not?
Lets say i have school. teacher wants to create collection in document for specific students, and few documents for all students in calss . how can i model this ?? I cant assign roles at such granular control
please you can explain how to use firebase database REST API
Could you do a video on Firestore pagination? Thank you very much for your video ;)
How about a crud datatable with sort, pagination and search, all server side
Quality content
Finally!

Great video! It would be even better if it was released few months ago when I was implementing security rules for my database.
Probably would've been best if you read the documentation :P
It would be the video if u even show the structure of firebase
my firestore work only in one device or on emulator.Whyyyyy?

This is awesome! We still need a backup solution that does not cost 1000$
Upvoted, even tho i cant get mine to work... only != null will work, all other rules will fuck me up
would have been great if you show us how the document snapshot looks like first
Thanks to Firestore Simulator!
