Client SDK

Call App Functions from the client SDK with auth headers injected automatically.

client.functions is a hand-written helper surface. It is consistent across SDKs, but unlike the generated REST core, it is not produced directly from OpenAPI.

Supported Client SDKs

• JavaScript (@edgebase/web)
• React Native (@edgebase/react-native)
• Dart / Flutter
• Swift
• Kotlin
• Java
• C#
• C++

Setup

JavaScript

import { createClient } from '@edgebase/web';

const client = createClient('https://my-app.edgebase.dev');

Dart/Flutter

import 'package:edgebase_flutter/edgebase.dart';

final client = ClientEdgeBase('https://my-app.edgebase.dev');

Swift

import EdgeBase

let client = EdgeBaseClient("https://my-app.edgebase.dev")

Kotlin

import dev.edgebase.sdk.client.ClientEdgeBase

val client = ClientEdgeBase("https://my-app.edgebase.dev")

Java

import dev.edgebase.sdk.client.ClientEdgeBase;
import dev.edgebase.sdk.client.EdgeBase;

ClientEdgeBase client = EdgeBase.client("https://my-app.edgebase.dev");

C#

using EdgeBase;

var client = new EdgeBase("https://my-app.edgebase.dev");

C++

#include <edgebase/edgebase.h>

client::EdgeBase client("https://my-app.edgebase.dev");

Basic Calls

JavaScript

const result = await client.functions.post('send-email', {
  to: 'user@example.com',
  subject: 'Welcome!',
});

const users = await client.functions.get('users');
await client.functions.delete('users/abc123');

Dart/Flutter

final result = await client.functions.post('send-email', {
  'to': 'user@example.com',
  'subject': 'Welcome!',
});

final users = await client.functions.get('users');
await client.functions.delete('users/abc123');

Swift

let result = try await client.functions.post("send-email", body: [
    "to": "user@example.com",
    "subject": "Welcome!",
])

let users = try await client.functions.get("users")
try await client.functions.delete("users/abc123")

Kotlin

val result = client.functions.post("send-email", mapOf(
    "to" to "user@example.com",
    "subject" to "Welcome!"
))

val users = client.functions.get("users")
client.functions.delete("users/abc123")

Java

var result = client.functions().post("send-email", Map.of(
    "to", "user@example.com",
    "subject", "Welcome!"
));

var users = client.functions().get("users");
client.functions().delete("users/abc123");

C#

var result = await client.Functions.PostAsync("send-email", new {
    to = "user@example.com",
    subject = "Welcome!"
});

var users = await client.Functions.GetAsync("users");
await client.Functions.DeleteAsync("users/abc123");

C++

auto result = client.functions().post(
    "send-email",
    R"({"to":"user@example.com","subject":"Welcome!"})"
);

auto users = client.functions().get("users");
client.functions().del("users/abc123");

Generic Call

JavaScript

const result = await client.functions.call('my-function', {
  method: 'PUT',
  body: { name: 'Updated' },
});

Dart/Flutter

final result = await client.functions.call(
  'my-function',
  options: const FunctionCallOptions(
    method: 'PUT',
    body: {'name': 'Updated'},
  ),
);

Swift

let result = try await client.functions.call(
    "my-function",
    options: FunctionCallOptions(
        method: "PUT",
        body: ["name": "Updated"]
    )
)

Kotlin

val result = client.functions.call(
    "my-function",
    FunctionCallOptions(
        method = "PUT",
        body = mapOf("name" to "Updated")
    )
)

Java

var result = client.functions().call(
    "my-function",
    new FunctionsClient.FunctionCallOptions(
        "PUT",
        Map.of("name", "Updated"),
        null
    )
);

C#

var result = await client.Functions.CallAsync("my-function", new FunctionCallOptions {
    Method = "PUT",
    Body = new { name = "Updated" }
});

C++

auto result = client.functions().call(
    "my-function",
    "PUT",
    R"({"name":"Updated"})"
);

Authentication

If the user is signed in, the SDK sends the auth token automatically.

await client.auth.signIn({ email: 'user@test.com', password: 'pass123' });
const profile = await client.functions.get('me/profile');

Server function:

export const GET = defineFunction(async ({ auth, admin }) => {
  if (!auth) throw new FunctionError('unauthenticated', 'Login required');
  return admin.db('shared').table('profiles').get(auth.id);
});

Notes

• React Native uses the same functions API shape as the web SDK.
• C++ uses JSON strings for request bodies instead of language-level map serialization helpers.
• Function routes are always resolved under /api/functions/*.
