Adds caching via localstorage to the flag creation form, so that if you
(accidentally) close the form before submitting it, you'll retain (most)
of the same data when you reopen it.
Specifically, we'll store:
- name
- description
- type
- tags
- impression data
We can't store the project as it is now, because it gets overridden by
whatever is in the URL. However, this is probably a good thing. It means
that if you navigate to a different project and open the feature
creation form there, it'll retain everything from the last one, but
it'll use the current project.
The stored data is cleared when you successfully create a feature, so
that you don't get dangling data.
The data is also stored in a shared cache for all projects, so that you
don't have different caches per project.
The behavior of seeding the form is hidden behind a flag (that doesn't
exist yet). We'll still read and write to the cache if the flag is off,
but we won't use it to populate the feature form, so it has no
discernible impact on the user.
## Bug detected 🐛 ... and squashed
Working on this, I came to realize that there was a bug in how the
config button and use feature form hooks interacted. We (in this case
probably me) have assumed that it's fine to use a set for any option
checking in the config buttons. Also, we're using a set to store tags in
the feature form. But objects aren't compared by value in JS, so the set
will happily accept multiple instances of the same tag. Likewise, these
tags won't show up as selected in the dropdown because when the dropdown
checks if the set `has` the value, it's using reference equality.
To get around this, I have normalized the values of the Tags set to
strings (`<type>:<value>`), which are easily comparable.
We can iterate on this later if we need to.
## `useLocalStorageState`
In doing this, I have also made a change to the useLocalStorageState
hook:
the exposed "setState" function now writes to the localstorage
immediately. This is because the useEffect method might not have time to
save the data if the component unmounts (this was the case with the flag
dialog).
However, I have kept the useEffect because it gets run on component
mount and then only when it changes. This means that we will get double
saves to localstorage, but it'll be with the same data, so it's benign.
I've tried out two other uses of the hook (event timeline props and
environment columns in the project flags table) and see no discernible
difference in behavior.
## `useFeatureForm`
I have also made a change to the useFeatureForm hook and removed a
`useEffect` that would reset the name to whatever you passed in as the
initial name if you cleared it out. This essentially meant that you
couldn't clear the name completely, because it would just refill with
the initial name.
As far as I can tell, there is no need to have this sticking around
anymore. The hook is only used in two places: the flag creation dialog
and the flag edit page. The flag edit page doesn't allow you to change
the name anyway and it was causing issues in the dialog. It's likely a
holdover from the way something worked 3 years ago. Both the dialog and
the edit screen seem to work just fine with this change.
I have also changed the function parameters from ordered parameters to
an object. There's so many of them that even you don't think it's a good
idea to use objects when you have multiple params with the same type,
it's just nigh-impossible to remember the order by now.
## Minor changes
Additionally, I came across three issues that were causing react errors,
and have fixed them.
1. we'd forgotten to interpolate a variable and just used the variable
name in a string instead
2. an html attribute that doesn't exist (`aria-role` instead of `role`)
3. Providing a disabled button inside a tooltip. I've seen this one
around for ages and it prevented tooltips from working on disabled
buttons. The solution was wrapping it in a span.

frontend
This directory contains the Unleash Admin UI frontend app.
Run with a local instance of the unleash-api
Refer to the Contributing to Unleash guide for instructions. The frontend dev server runs (in port 3000) simultaneously with the backend dev server (in port 4242):
yarn install
yarn dev
Run with a sandbox instance of the Unleash API
Alternatively, instead of running unleash-api on localhost, you can use a remote instance:
cd ./frontend
yarn install
yarn run start:sandbox
Running end-to-end tests
We have a set of Cypress tests that run on the build before a PR can be merged so it's important that you check these yourself before submitting a PR. On the server the tests will run against the deployed Heroku app so this is what you probably want to test against:
yarn run start:sandbox
In a different shell, you can run the tests themselves:
yarn run e2e:heroku
If you need to test against patches against a local server instance, you'll need to run that, and then run the end to end tests using:
yarn run e2e
You may also need to test that a feature works against the enterprise version of unleash. Assuming the Heroku instance is still running, this can be done by:
yarn run start:enterprise
yarn run e2e
Generating the OpenAPI client
The frontend uses an OpenAPI client generated from the backend's OpenAPI spec. Whenever there are changes to the backend API, the client should be regenerated:
For now we only use generated types (src/openapi/models). We will use methods (src/openapi/apis) for new features soon.
yarn gen:api
rm -rf src/openapi/apis
clean up src/openapi/index.ts imports, only keep first line export * from './models';
This script assumes that you have a running instance of the enterprise backend at http://localhost:4242.
The new OpenAPI client will be generated from the runtime schema of this instance.
The target URL can be changed by setting the UNLEASH_OPENAPI_URL env var.
