Authentication from cli tools can be a bit of a bear, and I have to look it up every time. This is my reference guide for future me to remember how to easily do it.

I set up a fastapi server running on port 8000, it uses a basic auth with waylonwalker as the username and asdf as the password. The server follows along with what comes out of the docs. I have it setup to take basic auth, form username and password, or a bearer token for authentication.

curl #

The og of command line url tools.

# basic auth
curl -u 'waylonwalker:asdf' -X POST localhost:8000/token
# basic auth with password prompt
curl -u 'waylonwalker' -X POST localhost:8000/token
# token
curl -H 'Authorization: bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ3YXlsb253YWxrZXIiLCJleHAiOjE3MDI5NTI2MDJ9.GeYNt7DNal6LTiPoavJnqypaMt4vYeriXdq5lqu1ILg' -X POST localhost:8000/token

wget #

My go to if I want the result to go into a file.

# basic auth
wget -q -O - --auth-no-challenge --http-user=waylonwalker --http-password=asdf --post-data '' localhost:8000/token

# token
wget -q -O - --header="Authorization: bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ3YXlsb253YWxrZXIiLCJleHAiOjE3MDI5NTI2MDJ9.GeYNt7DNal6LTiPoavJnqypaMt4vYeriXdq5lqu1ILg" -O - --post-data '' localhost:8000/token

httpx #

http-prompt localhost:8000 --auth waylonwalker:asdf --spec openapi.json

I am working on fokais.com’s signup page, and I want to hide the form input during an htmx request. I was seeing some issues where I was able to prevent spamming the submit button, but was still able to get one extra hit on it.

It also felt like nothing was happening while sending the email to the user for verification. Now I get the form to disappear and a spinner to show during the request.

html">HTML #

Let’s start off with the form. It uses htmx to submit a post request to the post_request route. Note that there is a spinner in the post_request with the htmx-indicator class.

The intent is to hide the spinner until the request is running, and hide all of the form input during the request.

<form
  id="signup-form"
  hx-swap-oob="outerHTML"
  class="m-4 mx-auto mb-6 flex w-80 flex-col rounded-lg b p-4 shadow-xlc shadow-cyan-500/10"
  method="POST"
  action="{{ url_for('post_signup') }}"
  hx-post="{{ url_for('post_signup') }}"

Yes this is styled using tailwindcss.

CSS #

Let’s take a look at how we achieve switching between only spinner an only form inputs using css.

.htmx-indicator {
  @apply hidden;
  opacity: 0;
  transition: opacity 500ms ease-in;
}
.htmx-request button,
.htmx-request input[type="submit"],
.htmx-request input,
.htmx-request label {
  @apply hidden;
}
.htmx-request .htmx-indicator {
  opacity: 1;
  @apply block;
}
.htmx-request.htmx-indicator {
  opacity: 1;
  @apply block;
}
