Specifying your OpenAPI description

To find out which endpoint to use, open the file Startup.cs and locate the code fragment that contains the text UseSwaggerUI. You should find this block of code:

if (env.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
    app.UseSwagger();
    app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "WebAPI v1"));
}

Use the endpoint you find and run the tool like this:

httprepl http://localhost:5000 --openapi /swagger/v1/swagger.json

If you do not find any references to swagger, then see None of the above worked, swagger isn't installed below, for how to install and configure swagger for your project.

Ignoring your environment

If specifying the Open API endpoint to use doesn't work, then you are not running your Web API in a development environment. So either use a development environment, or uncomment the if-statement while testing (to setup your environment for development, see Changing your environment below):

//if (env.IsDevelopment())
//{
    app.UseDeveloperExceptionPage();
    app.UseSwagger();
    app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "WebAPI v1"));
//}

Remember to restore the code you uncommented, if any, before you deploy to production.

Changing your environment

The profile your Web API is using, is specified in the file Properties\launchSettings.json. Open the file and search for ASPNETCORE_ENVIRONMENT. Then change the instances you find to:

"ASPNETCORE_ENVIRONMENT": "Development"

If this doesn't work, or the instances were already set to "Development", it means that you are not using any of the profiles specified in your launch settings. If no profile is used, ASPNETCORE_ENVIRONMENT defaults to "Production". When using the dotnet run command, the --launch-profile parameter lets you specify which profile to use:

dotnet run --launch-profile "name_of_profile"

As a last resort you can set the environment variable ASPNETCORE_ENVIRONMENT in the shell you are using, before you run the command dotnet run:

Bash

export ASPNETCORE_ENVIRONMENT=Development

CMD

set ASPNETCORE_ENVIRONMENT=Development

PowerShell

$env:ASPNETCORE_ENVIRONMENT='Development'

Then run the application without a profile :

dotnet run --no-launch-profile

The default ports, when running without a profile, should be 5000 or 5001. But read the output from the command, to see which ports it assigns to your Web API.

Please note, if you use VS Code to run your project, that VS Code may also have created launch settings in the .vscode\launch.json. It depends on how you have configured VS Code and what you allow it to do. I found some older articles, that claim that some extensions for VS Code, may interfere with the launch settings, but they didn't specify which ones.

None of the above worked, swagger isn't installed

I none of the above worked, it means you don't have swagger installed. Install swagger for your project and when done, try again.

Package Installation

Open your project in VS Code and run the following command from the Integrated Terminal and replace WebAPI.csproj with the name of your own project file:

dotnet add WebAPI.csproj package Swashbuckle.AspNetCore -v 5.6.3

You can of course run the command from outside VS Code, with your project folder as the current working directory.

Add and configure Swagger middleware

Add the Swagger generator to the services collection in the Startup.ConfigureServices method, as the last statement in the method:

public void ConfigureServices(IServiceCollection services)
{
    [... other code here ...]

    // Register the Swagger generator, defining 1 or more Swagger documents
    services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new OpenApiInfo { Title = "WebAPI", Version = "v1" });
    });

}

In the Startup.Configure method, enable the middleware for serving the generated JSON document and the Swagger UI, at the top of the method:

public void Configure(IApplicationBuilder app)
{
    // Enable middleware to serve generated Swagger as a JSON endpoint.
    app.UseSwagger();

    // Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.),
    // specifying the Swagger JSON endpoint.
    app.UseSwaggerUI(c =>
    {
        c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
    });

    [... other code here for setting up routing and the like ...]
}

QUESTION

What is a "closure" in Julia?

Asked 2022-Feb-03 at 18:34

I am learning how to write a Maximum Likelihood implementation in Julia and currently, I am following this material (highly recommended btw!). So the thing is I do not fully understand what a closure is in Julia nor when should I actually use it. Even after reading the official documentation the concept still remain a bit obscure to me.

For instance, in the tutorial, I mentioned the author defines the log-likelihood function as:

function log_likelihood(X, y, β)
    ll = 0.0
    @inbounds for i in eachindex(y)
        zᵢ = dot(X[i, :], β)
        c = -log1pexp(-zᵢ) # Conceptually equivalent to log(1 / (1 + exp(-zᵢ))) == -log(1 + exp(-zᵢ))
        ll += y[i] * c + (1 - y[i]) * (-zᵢ + c) # Conceptually equivalent to log(exp(-zᵢ) / (1 + exp(-zᵢ)))
    end
    ll
end

However, later he claims that

The log-likelihood as we've written is a function of both the data and the parameters, but mathematically it should only depend on the parameters. In addition to that mathematical reason for creating a new function, we want a function only of the parameters because the optimization algorithms in Optim assume the inputs have that property. To achieve both goals, we'll construct a closure that partially applies the log-likelihood function for us and negates it to give us the negative log-likelihood we want to minimize.

# Creating the closure
make_closures(X, y) = β -> -log_likelihood(X, y, β)
nll = make_closures(X, y)

# Define Initial Values equal to zero
β₀ = zeros(2 + 1)
# Ignite the optimization routine using `nll`
res = optimize(nll, β₀, LBFGS(), autodiff=:forward)

From the paragraph, I understand that we NEED to use it because it is how Optim's algorithm works, but I still don't get what is a closure in a broader sense. I will be more than grateful if someone could shed some light on this. Thank you very much.

ANSWER

Answered 2022-Feb-03 at 18:34

In the context you ask about you can think that closure is a function that references to some variables that are defined in its outer scope (for other cases see the answer by @phipsgabler). Here is a minimal example:

julia> function est_mean(x)
           function fun(m)
               return m - mean(x)
           end
           val = find_zero(fun, 0.0)
           @show val, mean(x)
           return fun # explicitly return the inner function to inspect it
       end
est_mean (generic function with 1 method)

julia> x = rand(10)
10-element Vector{Float64}:
 0.6699650145575134

 0.15751882823315777
 0.4227087678654101
 0.8594042895489912

julia> fun = est_mean(x)
(val, mean(x)) = (0.5463144770912497, 0.5463144770912497)
fun (generic function with 1 method)

julia> dump(fun)
fun (function of type var"#fun#3"{Vector{Float64}})
  x: Array{Float64}((10,)) [0.6699650145575134, 0.8208379672036165, 0.4299946498764684, 0.1321653923513042, 0.5552854476018734, 0.8729613266067378, 0.5423030870674236, 0.15751882823315777, 0.4227087678654101, 0.8594042895489912]

julia> fun.x
10-element Vector{Float64}:
 0.6699650145575134
 0.8208379672036165
 0.4299946498764684

 0.15751882823315777
 0.4227087678654101
 0.8594042895489912

julia> fun(10)
9.453685522908751

As you can see fun holds the reference to the x variable from the outer scope (in this case the scope introduced by the est_mean function). Moreover, I have shown you that you can even retrieve this value from outside of fun as its field (this is typically not recommended but I show this to you to prove that indeed fun stores a reference to the object x defined in its outer scope; it needs to store this reference as the variabe x is used inside the body of the fun function).

In the context of estimation, as you have noted, this is useful because find_zero in my case requires the function to take only one argument - the m variable in my case, while you want the return value to depend both on passed m and on x.

What is important that once x is captured in the fun closure it does not have to be in current scope. For instance when I call fun(10) the code executes correctly although we are outside of the scope of function est_mean. But this is not a problem because fun function has captured x variable.

Let me give one more example:

julia> function gen()
          x = []
          return v -> push!(x, v)
       end
gen (generic function with 1 method)

julia> fun2 = gen()
#4 (generic function with 1 method)

julia> fun2.x
Any[]

julia> fun2(1)
1-element Vector{Any}:
 1

julia> fun2.x
1-element Vector{Any}:
 1

julia> fun2(100)
2-element Vector{Any}:
   1
 100

julia> fun2.x
2-element Vector{Any}:
   1

Here you see that the x variable defined within gen function is captured by the anonymous function v -> push!(x, v) that I bind to the fun2 variable. Later when you call fun2 the object bound to the x variable gets updated (and can be referenced to) although it was defined in the gen function scope. Although we left the gen scope the object bound to the x variable outlives the scope because it is captured by the anonymous function we defined.

If something is unclear please comment.

QUESTION

running a vite dev server inside a docker container

Asked 2021-Dec-28 at 23:42

I have a Vue-cli app that I'm trying to convert to vite. I am using Docker to run the server. I looked at a couple tutorials and got vite to run in development mode without errors. However, the browser can't access the port. That is, when I'm on my macbook's command line (outside of Docker) I can't curl it:

$ curl localhost:8080
curl: (52) Empty reply from server

If I try localhost:8081 I get Failed to connect. In addition, if I run the webpack dev server it works normally so I know that my container's port is exposed.

Also, if I run curl in the same virtual machine that is running the vite server it works, so I know that vite is working.

Here are the details:

In package.json:

...
"dev": "vue-cli-service serve",
"vite": "vite",
...

The entire vite.config.ts file:

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

// https://vitejs.dev/config/
export default defineConfig({
    resolve: { alias: { '@': '/src' } },
    plugins: [vue()],
    server: {
        port: 8080
    }
})

The command that starts the container:

docker-compose run --publish 8080:8080 --rm app bash

The docker-compose.yml file:

version: '3.7'

services:
  app:
    image: myapp
    build: .
    container_name: myapp
    ports:
      - "8080:8080"

The Dockerfile:

FROM node:16.10.0

RUN npm install -g npm@8.1.3
RUN npm install -g @vue/cli@4.5.15

RUN mkdir /srv/app && chown node:node /srv/app

USER node

WORKDIR /srv/app

The command that I run inside the docker container for vite:

npm run vite

The command that I run inside the docker container for vue-cli:

npm run dev

So, to summarize: my setup works when running the vue-cli dev server but doesn't work when using the vite dev server.

ANSWER

Answered 2021-Nov-22 at 15:54

I figured it out. I needed to add a "host" attribute in the config, so now my vite.config.ts file is:

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

// https://vitejs.dev/config/
export default defineConfig({
    resolve: { alias: { '@': '/src' } },
    plugins: [vue()],
    server: {
        host: true,
        port: 8080
    }
})

ANSWER

Answered 2021-Dec-25 at 09:13

UPDATE:

For your firebase_core version is seems to be sufficient to pass the FirebaseOptions once you initialize firebase in your flutter code (and you don't need any script tags in your index.html):

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    // Replace with actual values
    options: FirebaseOptions(
      apiKey: "XXX",
      appId: "XXX",
      messagingSenderId: "XXX",
      projectId: "XXX",
    ),
  );
  runApp(MyApp());
}

Alternatively, one can also follow the updated official documentation and use the Firebase CLI to automatically create a firebase_options.dart file in your lib folder that will define the correct FirebaseOptions for you. The steps are:

Install Flutterfire CLI:

dart pub global activate flutterfire_cli

Configure Flutterfire (run in your project's root and go through the wizard selecting the correct Firebase project and target platforms):

flutterfire configure

Import the automatically generated firebase_options.dart file in your main.dart file and initialize Firebase as follows:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(MyApp());
}

PREVIOUS ANSWER:

From the docs:

The only way to currently add the Firebase SDKs to your Flutter web project is by importing the scripts from the Firebase content delivery network (CDN).

Therefore, please try to use script tags to import the relevant firebase components with version 8.6.1 as shown below (more info here):

  <script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-app.js"></script>
  <script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-analytics.js"></script>
  <script>
    var firebaseConfig = {
      apiKey: "xxx",
      authDomain: "xxx",
      projectId: "xx",
      storageBucket: "exxx",
      messagingSenderId: "xxx",
      appId: "xxx",
      measurementId: "xxx"
    };

    firebase.initializeApp(firebaseConfig);
    firebase.analytics();
  </script>

QUESTION

Approaches for using RTK-Query hooks inside functions?

Asked 2021-Dec-03 at 08:20

I've successfully written my application using Axios to fetch content. As of now, it's set up to fetch content when certain events happen (like the submit button has been clicked.) However, I'm experimenting with Redux's RTK-Query solution. This package generates hooks and in their examples, they provide simple component-level examples that call the hooks on mount.

How can I leverage these rtk-hooks (and hooks in general) so I can tie them to behaviors like onClick, onSubmit, and conditional events? I'm aware this conflicts with the rules-of-hooks guidelines, but I can't imagine RTK-Query would be so limited as to only allow component-level onMount API calls.

some related articles I'm reading while I try to figure this out / wait for a helpful example:

The second article seems somewhat relevant but I feel like its beating too far off the path and is making question if it's even worth having rtk-query installed. I might as well just use axios since it can be used anywhere in my components and logic. Can someone educate me on how to approach this problem? I'm new to rtk-query, it seems really cool but it also seems really restrictive in its implementation approaches.

Here is an example of my `api.ts` slice:

import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react';

const apiEndpoint = 'http://localhost:5000';

export const myApi = createApi({
  reducerPath: 'myApi',
  baseQuery: fetchBaseQuery({ baseUrl: apiEndpoint }),
  endpoints: builder => ({
    getFileById: builder.query<any, { id: string; fileId: string }>({
      query: arg => {
        const { id, fileId } = arg;
        return `/service/${id}/files/${fileId}`;
      },
    }),
  }),
});

// RTK Query will automatically generate hooks for each endpoint query
export const { useGetFileByIdQuery } = myApi;

generic example using axios:

const handleSubmit = async (): Promise<void> => {
    try {
      const getResponse = await axios.get('my-endpoint/abc/123');
    }
    catch (e) {
     ...
    }
}

ANSWER

Answered 2021-Sep-08 at 07:49

If you use a query, you would use local component state to set the query parameter

const [myState, setState] = useState(skipToken) // initialize with skipToken to skip at first
const result = useMyQuery(myState)

and in your click handler you then set the state

const changePage = () => {
  setState(5)
}

In your case though, you have a form submit and that sounds you want to use a "mutation", not a query. The point of mutations is that you are not really interested in the result long-term, but rather want to trigger a change on the server by sending data.

const [trigger, result] = useMyMutation()

that would be called like

const handleSubmit = () => {
  trigger(someValue)
}

QUESTION

Achieve Unique Column Width for each Cell in Different Rows with a GridPane?

Asked 2021-Nov-24 at 16:43

I am trying to model credit card data in JavaFx using a GridPane:

My model contains 3 rows (Note: each field is comprised of label + text field):

Row 1: First name and last name (4 fields)

Row 2: Credit card number (2 fields)

Row 3: Expiration date - month, year + CVV (6 fields)

See screenshot below:

I was reading this tutorial which states:

All cells in the same row will have the same height, and all cells in the same column will have the same width. Different rows can have different heights and different columns can have different widths.

Are there any workarounds to to have different size columns on a row by row basis in a GridPane?
