Wondering how to get started with security rules in your Cloud Firestore database? On this episode of Get to Know Cloud Firestore, Todd shows you how to make sure your clients only have access to the documents they're supposed to see, so you can do that whole "serverless computing" thing. Watch to find out about data validation, resource objects, custom auth claims, and much more!

how could you NOT, like the thumb bandage one...

[@RaphaelMattosatContextaWare]

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 :)

[@mayukhchakraborty5364]

To be honest, I never realized how 22 minutes passed, like in a snap

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!

Looking forward at early 2019 for Todd's video on #7- Hey we updated Firestore to support Geoqueries, collection group queries,OR queries. 😁

[@1002CK]

Tod always provide a great perspective to look at thing, and create product that is easier for us developer to use

[@Saturn2888]

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.

[@LuisCastillo-qh8wm]

Best videos series of this channel, as a developer I love it!

[@digitalml]

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...

[@gwapster13]

This is a great series. Please do a episode all about pagination.

Did the example for matching google.com contain a bug because it also matches [e-mail] ?

[@erwin_AI584]

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.

If you access to a document field from a security rule, does it count as a read? 💸

[@asdfghyter]

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.

[@hexadcml]

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

Excellent video, with a strong use case !

[@mdtamjeed]

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 } }

[@mymusicloversworld]

Very nicely presented and explained. 👍

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.

[@LarsRyeJeppesen]

Super super helpful

[@JBuchmann]

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)?

[@adebolalateef9094]

my exact question rn! seeing it's not being answered, I have to go elsewhere 😪

[@saikumarreddyatluri3332]

It would be the video if u even show the structure of firebase

[@apayrus]

Please, open the ability to translate subtitles to other languages. This material is interesting for many peoples. Not only for English speakers.

[@sutikshnadubey]

Nice Videos! It'd be great if Summary of rules/points can be given in description section.

[@Squad2ND]

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.

[@josefsantamaria]

[@adamm3122]

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.

[@thanhtung2922]

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 ?

[@jelmer-7790]

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?

[@AonghasAnderson]

Super super useful!

[@abdouseck4894]

This is awesome! We still need a backup solution that does not cost 1000$

[@connelhooley]

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?

[@nimamc]

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.

[@alexandregagne4151]

Could you do a video on Firestore pagination? Thank you very much for your video ;)

[@rubenheymans1988]

How about a crud datatable with sort, pagination and search, all server side

[@alexeyiskrov2845]

Great video! It would be even better if it was released few months ago when I was implementing security rules for my database.

[@b5a5m5]

Probably would've been best if you read the documentation :P

[@paoluccij]

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

[@bitculator]

Upvoted, even tho i cant get mine to work... only != null will work, all other rules will fuck me up

[@dabblewriter]

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?

[@dinushkam2444]

hidden got you in Firebase

[@zzong8035]

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?

[@kimduer6194]

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?

[@Jb67912]

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?

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; match /users/{uid}/products/{product}{ allow read; allow create: if request.auth.uid != null; allow delete,update: if request.auth.uid == uid; } } } } } }

How can i block any http get request even if i havent written any rules???

[@bitculator]

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...
