PostgREST client-side library 🦀. This library provides an ORM interface to PostgREST.
Add this to your Cargo.toml:
[dependencies] postgrest = "1.0"
Simple example:
use postgrest::Postgrest; let client = Postgrest::new("https://your.postgrest.endpoint"); let resp = client .from("your_table") .select("*") .execute() .await?; let body = resp .text() .await?;
Simple example with JWT auth
use postgrest::Postgrest; let client = Postgrest::new("https://your.postgrest.endpoint"); let resp = client .from("your_table") .auth("VerySensitiveJWTValueAsStringOrStr") .select("*") .execute() .await?; let body = resp .text() .await?;
Simplified example using a custom header (e.g. for API gateway authentication with Supabase).
use postgrest::Postgrest; let client = Postgrest::new("https://your.supabase.endpoint/rest/v1") .insert_header("apikey", "ExampleAPIKeyValue"); // EXAMPLE ONLY! // Don't actually hard code this value, that's really bad. Use environment // variables like with the dotenv(https://crates.io/crates/dotenv) crate to inject let resp = client .from("your_table") .select("*") .execute() .await?; let body = resp .text() .await?;
Secure example with authenticated API gateway using the dotenv crate to correctly retrieve sensitive values.
use postgrest::Postgrest; use dotenv; dotenv::dotenv().ok(); let client = Postgrest::new("https://your.supabase.endpoint/rest/v1") .insert_header( "apikey", dotenv::var("SUPABASE_PUBLIC_API_KEY").unwrap()) let resp = client .from("your_table") .select("*") .execute() .await?; let body = resp .text() .await?;
if you have RLS enabled you're required to add an extra header for this libary to function correctly.
use postgrest::Postgrest; use dotenv; dotenv::dotenv().ok(); let client = Postgrest::new("https://your.supabase.endpoint/rest/v1/") .insert_header( "apikey", dotenv::var("SUPABASE_PUBLIC_API_KEY").unwrap()) .insert_header("Authorization", format!("Bearer {}", SERVICE_KEY)); let resp = client .from("your_table") .select("*") .execute() .await?; let body = resp .text() .await?;
These examples assume you've already initialized the client. The methods .from() and .rpc() initalizes the query builder inside the client.
Using filters:
let resp = client .from("your_table") .eq("country", "Germany") .gte("id", "20") .select("*") .execute() .await?;
Updating a table:
let resp = client .from("your_table") .eq("username", "soedirgo") .update("{\"organization\": \"supabase\"}") .execute() .await?;
Executing stored procedures:
let resp = client .rpc("add", "{\"a\": 1, \"b\": 2}") .execute() .await?;
Not enough filters:
let resp = client .from("countries") .eq("name", "New Zealand") // You can filter for equality... .gt("id", "20") .lt("id", "20") .gte("id", "20") .lte("id", "20") .like("name", "%United%") // ...do pattern matching... .ilike("name", "%United%") .is("name", "null") .in_("name", vec!["China", "France"]) .neq("name", "China") .fts("phrase", "The Fat Cats", Some("english")) // ...do full text search... .plfts("phrase", "The Fat Cats", None) .phfts("phrase", "The Fat Cats", Some("english")) .wfts("phrase", "The Fat Cats", None) .cs("countries", "(10,20)") .cd("countries", "(10,20)") .ov("population_range", "(100,500)") .sl("population_range", (100, 500)) // ...and range operations! .sr("population_range", (100, 500)) // Find out more about the filters at: .nxl("population_range", (100, 500)) // https://postgrest.org/en/stable/api.html#operators .nxr("population_range", (100, 500)) .adj("population_range", (100, 500)) .select("*") .execute() .await?;
