edge.yaml config ideas

By default no config is required when developing and deploying, however providing such a file would allow the CLI to hook onto various options:

Support multiple entry points. For example, lib/admin.dart could deploy as it's own standalone function. Currently, only a single entrypoint is supported.

[BUG] Supabase: Cannot read request.body contents

In Supabase functions Request.body cannot be read ever.

Taking this as a base example it always return "Body not used" (independently if you send body in your post request or not:

Example cURL:

curl  -X POST -d '{"message":"This is a test"}' http://localhost:54321/functions/v1/dart_edge

main.dart

import 'package:supabase_functions/supabase_functions.dart';

void main() {
  SupabaseFunctions(fetch: (request) {
    if (request.bodyUsed) {
      return Response("Body used! - Contents: ${request.body}");
    } else {
      return Response("Body not used");
    }
  });
}

If you try to read the body directly there is an error:

import 'package:supabase_functions/supabase_functions.dart';

void main() {
  SupabaseFunctions(fetch: (request) {
    if (request.body != null) { // accesing body directly
      return Response("Body used! - Contents: ${request.body}");
    } else {
      return Response("Body not used");
    }
  });
}

Not working as per superbase Docs

I have fallowed the docs of superbase to run dart edge in superbase platform. but even hello world function also not working

doc: https://supabase.com/docs/guides/functions/dart-edge

Support Firebase / GCP Cloud Functions

Support for Firebase or GCP cloud functions would be incredible. A lot of developers use Firebase as their preferred BaaS.

Happy to assist should someone be able to point me in the right direction.

Cannot use `SupabaseClient` without dart:html or dart:io in Supabase Edge functions

Describe the bug
The SupabaseClient constructor throws "Cannot create a client without dart:html or dart:io." error when used in Supabase Dart Edge functions with the supabase_functions package.
An error message looks like the following:

[Error] ub {
  a: "Cannot create a client without dart:html or dart:io.",
  "$thrownJsError": Unsupported operation: Cannot create a client without dart:html or dart:io.

}

To Reproduce
main.dart:

import 'package:edge_http_client/edge_http_client.dart';
import 'package:supabase/supabase.dart';
import 'package:supabase_functions/supabase_functions.dart';

void main() {
  SupabaseFunctions(fetch: (request) {
    final supabaseUrl = Deno.env.get('SUPABASE_URL')!;
    final supabaseKey = Deno.env.get('SUPABASE_SERVICE_ROLE_KEY')!;

    // This SupabaseClient constructor throws an error:
    SupabaseClient(
      supabaseUrl,
      supabaseKey,
      httpClient: EdgeHttpClient(),
    );

    return Response('OK');
  });
}

Cloudflare Workers not working on Dart 3.3?

Since I found the project recently we are on Dart 3.3 but I got a lot of errors without changing anything, then tried to updated some version on pubspec.yaml but nothing changed on errors:

I followed dart pub site instructions for Cloudflare Workers, everything worked fine til I asked to build:

⚡ dart run edge build cloudflare_workers --dev

I'm using Sonoma.

Since I found this project very promising I'm to help fix any issue if possible. Thank you.

Cloudflare workers template (feedback)

Just some things I've noticed when using the template;

generated pubspec.yaml has hardcoded name
generated wrangler.toml has hardcoded name
generated pubspec.yaml should have publish_to: none by default
.gitignore has .vercel in it
a basic readme would be nice
adding the default analysis_options.yaml would be nice
Uint8List should be valid body type, PR: #10

Support Netlify Edge Functions

Netlify offers an integration integartions to work with the Netlify CLI. We've got a package setup to handle this integration but it needs some love. There's a few things to figure out:

Netlify CLI first scans for generated functions, and then runs the provided build command. This means it first starts with no functions, or old ones & serves them. Once that's complete, it then runs the compiler, detects a new function and reloads. This causes a bit of a janky developer experience.

Another issue seems to be that Netlify isn't detecting file changes from a process, and thus doesn't reload the server. Manually saving the file triggers a build, so need to investigate what's going on there.

An error occurred: NoSuchMethodError: method not found: 'constructor' on null

Randomly when executing a function cold, it will throw this error. I do not seem to see this error after a function is warmed, but if it goes cold and requires first boot again, this is sometimes thrown. Very hard to track from my end, but seems something is being called before everything is fully loaded into memory in some situations?

docs(cloudflare/request-properties): Invalid property access

Looks like request.cf property does not expose ipAddress.

Fix would be to do request.headers['cf-connecting-ip'] instead.

dart_edge/docs/platform/cloudflare/request-properties.mdx

Line 15 in 18ae5d6

print('IP Adress: ${request.cf.ipAddress}');

Error while accessing empty KV keys

While accessing non existing kv keys, currently it's throwing an error.
Unhandled Promise Rejection: Error: TypeError: null: type 'JSNull' is not a subtype of type 'FutureOr<String>'

I'm no expert in these, but a better idea would be to make the return type of get from kvNamespace from Future<String> to Future<String?> . Then we can check if the key exists by checking if the value is null.

edge is not able to execute dart to js commands in Ubuntu [ Linux OS] [ Supabase edge functions]

and when i run exact command in teriminal it's working fine

dart compile js -O4 --no-frequency-based-minification --server-mode -o /home/rr-reddy/StudioProjects/milkman_edge_project/supabase/functions/task1/main.dart.js /home/rr-reddy/StudioProjects/milkman_edge_project/lib/task1.dart

serving edge functions in supabase is also not wokring

Small workaround is adding dart command with full path as below ( line no: 7)

How to fetch environment variables?

const testEnvVar = String.fromEnvironment(
    'SUPABASE_URL',
    defaultValue: 'defaultVal',
  );

The env var SUPABASE_URL comes built in as a default secret, per https://supabase.com/docs/guides/functions/secrets, yet defaultVal is returned.

UnsupportedError occurs when using the HTTP package on the Supabase platform

I am running on Supabase Edge.

As far as I understand from Fetching Data, it is possible to fetch data using two approaches, Fetch and HTTP Package.

However, the sample does not describe how to use it with platforms such as Supabase or Vercel using http.runWithClient.

When I tried writing the following code, an UnsupportedError occurred:

UnsupportedError {
  message: "Cannot create a client without dart:html or dart:io.",
  "$thrownJsError": Unsupported operation: Cannot create a client without dart:html or dart:io.

}

Reproducible code

void main() {
  http.runWithClient(() async {
    SupabaseFunctions(fetch: (request) async {
      // Get IP address
      final response = await http.get(
        Uri.parse('http://httpbin.org/ip'),
        headers: {'Content-Type': 'application/json'},
      );
      if (response.statusCode == 200) {
        final json = response.body as Map<String, dynamic>?;
        print(json);
        return Response.json(json);
      }
      return Response.error();
    });
  }, () => EdgeHttpClient());
}

Is my usage incorrect? Or is the HTTP package not yet supported in Supabase?
It was available with the Fetch API.

I want to use packages like dart_openai | Dart Package, but since their internal implementation depends on http, I cannot use them without resolving the above issue.

Thanks.

Provide out of the box `fetch` HttpOverride

The fetch API is very much a JavaScript concept, so for Dart developers it might be a bit confusing and not intuitive to use. It's most likely they'll reach for a library such as dio or http, however these all use the underlying XMLHttpRequest interface which isn't available on edge runtimes.

In theory, we can use a HttpOverride which internally uses the fetch API, and attach this as an override when using a provider. Then all Dart HTTP libraries should work as expected via the fetch API.

How to use it in Docker

Multiple functions support ?

I've browsed around but I'm not sure to understand how it is intended to be used to use multiple functions. Do we need one dart project for each function ?

Migrate to `typings` as `js_bindings` is discontinued

js_bindings is extensively used throughout the repo, but it's discontinued in favour of typings.

Typings also has Deno bindings generated so a lot of code is not needed anymore.

`edge build supabase_functions` doesn't compile anything.

dart_edge/packages/edge/lib/src/commands/build_commands/build_supabase.dart

Line 58 in 8227854

Future<void> runBuild() async {}

The runBuild method is empty. I'm not sure but shouldn't it be something like

 Future<void> runBuild() async {
    final functionDirectory = Directory(
      p.join(Directory.current.path, 'supabase', 'functions', 'dart_edge'),
    );

    final compiler = Compiler(
      logger: logger,
      entryPoint: p.join(Directory.current.path, 'lib', 'main.dart'),
      outputDirectory: functionDirectory.path,
      outputFileName: 'main.dart.js',
      level: CompilerLevel.O1,
    );

    await compiler.compile();
}

How to implement functions logging (`print()` or whatever else)

Plain print() calls now generate INFO messages on Supabase.

How can we implement a full logging system with different logging levels?

cloudflare: `Response.json()` errors (type error)

Reproduction:

Not sure if misunderstanding the API though, it's typed as Object? however with no code docs so not clear what it should be? Even Response.json("{}") errors

Can I create a new DART edge project within an existing Flutter project?

Can I create a new DART edge project as a sub folder within an existing Flutter project? This is because I want to reuse data model classes already defined in the Flutter project.

Support for Vercel Storage

Vercel has recently added its own suite of managed, serverless storage products:

Vercel KV: Durable Redis
Vercel Postgres: Serverless SQL
Vercel Blob: Large file storage
Vercel Edge Config: Global, low-latency data store

It would be nice if Dart Edge supported these new APIs, to assist developers who want to build Vercel applications with Dart Edge.

How to make multi-part/form-data request in edge_http_client package?

Hey guys, loving this package in the edge function. but any plans to add muliPartRequest to the package?

Missing some query string params when multiple are used with supabase_edge_functions

I've deployed this after compiling it with edge build supabase_functions --dev as the main isn't working.

However , I expected to get all the query params with the following call:

import 'package:edge/edge.dart';
import 'package:supabase_functions/supabase_functions.dart';


void main() {
    SupabaseFunctions(fetch: (request) async {
        final text = request.url.queryParameters['text'] ?? 'Hello, world!';
        final height = request.url.queryParameters['height'] ?? '630';
        final length = request.url.queryParameters['length'] ?? '1200';
        final pattern = request.url.queryParameters['pattern'] ?? '';
        final pcolor = request.url.queryParameters['pcolor'] ?? '#040703';
        final scolor = request.url.queryParameters['scolor'] ?? '#055C13';
        final text_color = request.url.queryParameters['text_color'] ?? '#FFFFFF';
        final svg = generateOGImage(text, int.parse(height), int.parse(length), pattern, pcolor, scolor, text_color);
        final headers = Headers({'Content-Type': 'text/plain', 'Cache-Control': 'public, max-age=3600'});
        String all_query_string = 'Text: $text \nHeight: $height \nLength: $length \nPattern: $pattern \nPrimary Color: $pcolor \nSecondary Color: $scolor \nText Color: $text_color'; 
        return Response(utf8.encode(all_query_string),
        status: 200,
        headers: headers
                       );
    });
}

For example a call to:

https://jpzwvyukydqlzwgvncyj.functions.supabase.co/dart_edge?pattern=surf&scolor=#FFFFFF&text_color=#FF0000&text=generate%20images%20with%20dart%20edge

Should return:

Text: Generate images with dart edge
Height: 630 
Length: 1200 
Pattern: surf 
Primary Color: #040703 
Secondary Color:  #FFFFFF
Text Color: #FF0000

I get the following:

Text: Hello, world! 
Height: 630 
Length: 1200 
Pattern: surf 
Primary Color: #040703 
Secondary Color:  
Text Color: #FFFFFF

Another example as it seems that terms disappear and even get swapped randomly:

https://jpzwvyukydqlzwgvncyj.functions.supabase.co/dart_edge?pattern=surf&height=800&text=generate%20images%20with%20dart%20edge&pcolor=#100000&scolor=#FFF&text_color=#FF0000

Expected results:

Text: generate images with dart edge 
Height: 800 
Length: 1200 
Pattern: surf 
Primary Color: #100000
Secondary Color:  #FFF
Text Color: #FF0000

Actual results:

Text: generate images with dart edge 
Height: 800 
Length: 1200 
Pattern: surf 
Primary Color:  
Secondary Color: #055C13 
Text Color: #FFFFFF

Send an email inside a Edge function

Hi,
I can send an email using SMTP in Typescript.

import { SMTPClient } from "https://deno.land/x/denomailer/mod.ts";
....
  const smtp = new SMTPClient({
    connection: {
      hostname: Deno.env.get('_SMTP_HOSTNAME')!,
      port: Number(Deno.env.get('_SMTP_PORT')!),
      tls: true,
      auth: {
        username: Deno.env.get('_SMTP_USERNAME')!,
        password: Deno.env.get('_SMTP_PASSWORD')!,
      },
    },
  });
...
await smtp.send({ ....})

However I would prefer to use Dart on the Edge functions.
I tried to use the mailer library but it doesn't work. issue
What is the best way to achieve this?
I can't seem to find a solution in the web, which is weird because I thought it would be a usual feature.
Am I overlooking something?
Thank you for any tips

Info: The unavailable library 'dart:html' is imported through these packages:

    package:supabase_edge_functions_example => package:dart_openai => package:fetch_client => package:fetch_api => dart:html

Any edge function that references packages that nest dart:html should trigger this.

https://github.com/anasfik/openai
uses
https://github.com/Zekfad/fetch_client
uses
https://github.com/Zekfad/fetch_api

Example:

create new edge function

dart pub add fetch_api

import 'package:supabase_functions/supabase_functions.dart';
import 'package:fetch_api/fetch_api.dart' as api;

void main() {
  SupabaseFunctions(fetch: (request) {
    void main() async {
      // Simple cors request
      final response = await fetch(
        Resource('https://api.restful-api.dev/objects/1'),
      );

      print(await response.text());
    }

    return Response("Hello from Supabase Edge Functions!");
  });
}

This all makes sense in that dart_edge has created a custom fetch client, but some packages use custom fetch clients as well. I am attempted to get the dart_openai package to work, which uses conditional importing of the referenced fetch package here:

https://github.com/anasfik/openai/blob/aa42ccee89c0fef5b4102eceee11d28890d0bcdb/lib/src/core/networking/client.dart

if I remove the conditional import so that it only sees the http_client_io, the package will compile as an edge function. If the conditional import is present based on dart.library.io, or even refactoring the imports to look like this

import 'package:dart_openai/src/core/utils/http_client_io.dart'
    if (dart.library.js) 'package:dart_openai/src/core/utils/http_client_web.dart'
    if (dart.library.io) 'package:dart_openai/src/core/utils/http_client_io.dart';

I run into the error referenced above as the import takes the web path. I am not sure if this is directly a dart_edge issue, but thought I would start here as it is likely similar imports / nesting of dart:html will be found across the package ecosystem.

How to send http request?

I tried to use this library: https://pub.dev/packages/http but it gives me an error. What else I can use?

main.dart.js -- Generated file improper usage of .toString

After generating my edge function, I received

error: Uncaught TypeError: Cannot read properties of undefined (reading 'toString')
      t1.toString;

      t1 = A._asStringQ(self.Deno.env.get("OPENAI_API_KEY"));
      t1.toString;

I'm not sure if the code generation is directly handled by dart edge. As you can see, the root of this comes from a Deno.env variable. It may be more proper to always add these to a empty string. The issue is fixed after removing

t1.toString;

I think this happens because of the way this library maps the String value to the OpenAI type --
OpenAI.apiKey = edge.Deno.env.get('OPENAI_API_KEY')!;

the occurrence of this convention might be rare, but this issue will at minimum serve to help others know they can simply remove the .toString from generated code.
