refactor: [M3-7380] - Use `volumes/types` endpoint for pricing data #10376

mjac0bs · 2024-04-12T16:56:19Z

Description 📝

API is now returning pricing data through the /volumes/types endpoint.

In this PR, prices can be dynamically displayed for base region pricing and DC-specific region pricing, using the prices returned in the new endpoint, for Volumes.

Changes 🔄

Created the necessary api-v4 endpoint, query, and interface to use the volumes/types endpoint.
Modified getDCSpecificPriceByType to optionally accept a size param, if size is a factor of price and updated util unit test accordingly.
Created the necessary factory and endpoint in the MSW to support a mocked response to the API endpoint.
Added UX for error handling in the unlikely event that pricing cannot be calculated: disable create button and display tooltip error.
Added loading state for display prices.
Updated create-volume-smoke.spec.ts to test create volume error flows.

Note: I did not update the resize or clone Cypress tests to test those error flows. These existing specs run slowly since they have to create a linode and I'm not sure it's worth it for an edge-case like this, so held off doing that and will talk to Joe when he returns.

Preview 📷

The only visual changes should be loading state for pricing and the disabled Create Volume, Resize Volume, and Clone Volume buttons if the price is invalid (e.g. undefined).

How to test 🧪

Prerequisites

(How to setup test environment)

Check out this PR and yarn up.
All new types endpoints are all in prod, so use the prod environment.
Have an existing linode or create one.

Verification steps

(How to verify changes)

Go to http://localhost:3000/volumes/create.
Fill out the form.
Verify price calculation is correct by testing different options for the Region and comparing with prod.
Confirm:
- There are no regressions in decimal point value or calculations displayed in the UI.
- $0 is a valid region price if returned from the API, the user sees $0 pricing, and a volume can be created. (Update the mock data to test this.)
- A user can still create a Volume.
- If price cannot be calculated (e.g. it is undefined), the Summary displays the unknown price ($--.--) string, the Create button is disabled, and a tooltip displays on hover. (Blocking network requests is one method.)
- When a region is not yet selected, the Create button is still enabled. (Pricing can't be calculated yet; we don't know if the price is invalid.)
- Loading state functions as expected.
Additionally, confirm the above when creating or resizing a volume from a linode:
- via Linode Details > Storage > Create Volume
- via Linode Details > Storage > Clone (the volume you created in the last step)
- via Linode Details > Storage > Resize (the volume you created)

This cleaned up an unrelated inconsistency in our error notice. important does not work without a variant prop, and we shouldn't useimportant here, anyway, to be consistent with how we displayed these errors elsewhere. I added the error variant that was missing.

I think we want to use the warning variant for permissions banners, cause it's not technically an error

I went back to check what we've done in other "Restricted User Access" PRs and it does look like we're using an error with this. I'm going to keep it an error here for consistency.

Billing access PR: #10201
Nodebalancer PR: #10095

If we want to discuss error vs warning for these restricted access notices, let's bring it up with UX in cafe, @abailly-akamai. (cc @jaalah-akamai)

Did a little bit of renaming for clarity here and also added loading state to the price display for volumes create page to improve the slow network or error experience.

We can remove getDynamicVolumePrice entirely now that we have price data in the /types endpoint; we just have to allow an optional size to be passed into getDCSpecificPriceByType. Test coverage is updated here accordingly.
