Problem details for HTTP APIs HTTP status codes are sometimes not sufficient to convey enough information about an error to be helpful. The RFC 7807 defines simple JSON and XML document formats to inform the client about a problem in a HTTP API. It's a great start point for reporting errors in your API. It also defines the application/problem+json and application/problem+xml media types.

Mailgun is primarily a developer’s tool so the best way use Mailgun is through our APIs.

The web API is now the most common meaning of the term API

"detail": [ { "loc": [ "body", "name" ], "message": "Field required" }, { "loc": [ "body", "email" ], "message": "'not-email' is not an 'email'" } ]

For example, let’s consider the type property. For most of the projects I am working on, it isn’t practical to have a webpage dedicated to each type of possible error.

For the instance property, the most practical way I’ve found of implementing this is to define a URN that encapsulates additional information regarding the error. Here is an example URN for reference. urn:companyname:api:error:protocol:badRequest:f29f57d7-e1f8-4643-b226-fa18f15e9b71

"type": "https://example.com/problems/request-parameters-missing"

ErrorResponse: description: Container object for one or more errors returned by the API. type: object required: - errors properties: errors: type: array items: $ref: '#/definitions/Error'

FetchErrorResponse: type: object properties: meta: $ref: '#/definitions/FetchMetaResponse' errors: $ref: '#/definitions/Error' example: { "meta": { "req_id": "d07c8b12-c95e-4a06-8424-92aac94bb445" }, "errors": [{ "code": "Unauthorized", "detail": "A valid bearer token is required", "status":"401" } ] }

The valueAsNumber IDL attribute represents the value of the element, interpreted as a number. On getting, if the valueAsNumber attribute does not apply, as defined for the input element's type attribute's current state, then return a Not-a-Number (NaN) value.

Capacitor's origins lie in Ionic's mission to provide a holistic framework for developing hybrid apps—apps that run on mobile devices, on desktops, and in the browser. It does not only replace Apache Cordova as a “bridge” to native platform access in new Ionic projects but also “provides a consistent, web-focused set of APIs”.

Capacitor is a framework that provides developers a coherent API set to access various features on different platforms. By doing so, it also simplifies using those features. Especially for web APIs that are hard to use or require multiple steps to set them up, Capacitor provides an easy-to-use interface.

Another problem I ran into was knowing when an element is removed. I had to add a MutationObserver on the current tooltip target so if it gets removed by Svelte while the tooltip is visible (e.g. if a click moves to another route) the tooltip isn't left hanging around on the screen. No mouseleave/mouseout events are dispatched on elements that are removed.
