This package provides utilities for reading & writing Google Firestore documents with Julia using the REST API.

This package is unofficial and not sponsored or supported by Google.

1. Create a new Firebase project at https://firebase.google.com.
2. Create a Firestore Database in your project.
3. In your .julia/startup/config.jl file, add ENV["FIRESTORE_PROJECT"] = "<my_project_id>".

• Alternatively, use Firestore.set_project!(::String).

Firestore supports the following datatypes (in Julia-speak):

• Bool
• Int64
• Float64
• Nothing
• String
• DateTime
• Dict{String, SupportedType}
• Vector{SupportedType}

Firestore.jl will convert your data into the appropriate type if it is able to do so (e.g. OrderedDict -> Dict).

using Firestore
using Dates

doc = Dict(
    :x1 => 1,
    :x2 => "a string",
    :x3 => Dict(:sub1 => 1, :sub2 => [1, "two"]),
    :x4 => false,
    :x5 => nothing,
    :now => now(),
    :today => today(),
    :x7 => [1, "two", Dict("three" => 3)]
)

# `patch` will overwrite an existing doc whereas `createDocument` will not
Firestore.patch("test_collection/test_doc", doc)

Firestore.get("test_collection/test_doc")

Dict{Symbol, Any} with 8 entries:
  :today => DateTime("2021-03-29T00:00:00")
  :x2    => "a string"
  :x5    => nothing
  :x7    => Any[1, "two", Dict(:three=>3)]
  :x3    => Dict{Symbol, Any}(:sub2=>Any[1, "two"], :sub1=>1)
  :x4    => false
  :now   => DateTime("2021-03-29T14:21:17.409")
  :x1    => 1

• createDocument
• delete
• get
• patch

• NOTE: Currently only email/password-based auth is supported.

1. Go to your Firebase "Authentication" page:

• Under "Sign-In Method", enable the "Email/Password" provider.
• Under "Users", add your email and password.
• Add ENV["FIRESTORE_EMAIL"] = <your email> and ENV["FIRESTORE_PASSWORD"] = <your pw> to your ~/.julia/startup/config.jl file.

2. Go to your Project Settings (Click the cog next to "Project Overview") page:

• Add ENV["FIRESTORE_API_KEY"] = <Web API Key> to your ~/.julia/startup/config.jl

3. Go to your Firebase "Firestore Database" page:

• Copy/paste this to your "Rules":

// Allow read/write access on all documents to any user signed in to the application
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

4. Call get_token!() and now your requests are authenticated!
