QUESTION
I want to convert an object structure to a structure which the Json-rules-engine can use.
I have this array as input, where A, B, C, D and E are some arbitrary condition.

I am using a CDN in Azure and its a Standard Verizon. Is it possible to do the Automatic Redirection from HTTP to HTTPS? I know that I can do this if the CDN is a Standard Azure CDN from Microsoft.
Set up the Standard rules engine for Azure CDN
it is possible to do this with a Standard Verizon CDN because the Rules Engine tab is not available to this.

I am attempting to use an Apollo Client on a node.js server to interface with another GraphQL API using the following code:
...ANSWER
Answered 2018-Jun-04 at 22:31It turns out that the ApolloClient
provided by the apollo-boost
library does not accept a link
option. Switching to use the vanilla apollo-client
allows you to specify your fetching mechanism.
Although apollo-boost
and apollo-client
both export an ApolloClient
in the docs, they take wildly different options.
QUESTION
I've been struggling with the following problem for the last few days and due to the very nature of a CDN and the manual review of each new rule, it takes me each time up to 4h to deploy a new rule.
As described in the following topic, I currently have my Angular application deployed to a storage account which has a single blob container called cdn
Within the root of this blob container, the whole dist
folder from my angular project has been copied via my CI setup.
The CDN profile has also been set up, to point at the origin-path
called /cdn
Unfortunately there is currently an ongoing issue that you can't directly access a default file.
What I would like is to redirect all incoming traffic from my Angular application to the
index.html
file. This in order to satisfy the routing for Angular.Furthermore I would like to let any request for static files (e.g images) through without any specific url rewritting.
I've seen various posts regarding this issue but none of the answer seem to cover my case or didn't in the deliver the expected result.
Currently I am using the rules engines feature of the Azure CDN from Verizon.
Regarding the patterns I used all the patterns mentioned in the following article, including which were mentioned in the comments.
I've also spent at least two days to find various other articles and stackoverflow articles but none of them worked for my case.
Furthermore I also created my own regex pattern but although they worked in my test environment, they would work once they were deployed to the CDN.
I usually ended up with one of the following results:
- Top level domain
https://myFancyWebsite.azureedge.net
wouldn't rewrite the url to theindex.html
and I would receive a http error404
- Top level domain would redirect to
index.html
but would stop working once I added a url pathhttps://myFancyWebsite.azureedge.net/login/callback
- once again a http error404
as soon as I started using/login/callback
- Top level domain would rewrite the url to something like
https://myFancyWebsite.azureedge.net/cdn/cdn/cdn/cdn/cdn/cdn/cdn/cdn/cdn/cdn ....
in an http error431
The offical documentation from Microsoft also didn't help in my case.
I am pretty sure I am not the first one who is deploying an Angular application to storage account and someone has run in the same issues as I have.
I am thankful for any information which points me in the right direction because at the moment I am definitely thinking about moving away from whole storage account deployment.
Update 1With the following source
pattern ((?:[^\?]*/)?)($|\?.*)
which was also mentioned in the article over here, I am able to handle at least the top level domain rewrite to the index.html
file.
Unfortunately, I still need an additional pattern to redirect from https://myFancyWebsite.azureedge.net/login/callback
to https://myFancyWebsite.azureedge.net/index.html
I am currently updating the regex pattern once or twice a day and once again it works on my test environment but stops working once I deploy it. I start to believe that Azure CDN is appending something to the URL after the top-level domain but I have no idea how to verify that.
https://regex101.com/r/KK0jCN/23
Update 3We are writting the year 3025 and I still have no clue why for example the following pattern isn't handling the url rewritting of the top domain.
...ANSWER
Answered 2018-Mar-29 at 07:08For your requirement, I tested this issue on my side. Per my test, you could try to leverage the following URL Rewrite rule:
Source pattern: (http[s]?://[^\?/#]+)(/(?!images)(?!scripts)[^\?#]*)?($|[\?#].*)
Destination pattern: $1/index.html$3
Note: For loading other files (.ico,.txt,.js,.css,etc) correctly, you need to move them into new virtual directories instead of the root of your blob container. For example, you could move image files into cdn\images
and move JavaScript files into cdn\scripts
, then the regular expression would ignore the related virtual folders.
Additionally, you could use Azure Web App to host your static website and choose the Free pricing tier or the Shared tier which would cost you $9.49 per month per instance. Details you could follow Pricing calculator.
UPDATE:
Based on Justin's answer, I checked this issue and found that for Blob storage origin type, the Source
and Destination
under URL Rewrite are talking about the request against the blob storage endpoint. So we need to set regular expression against the request path and query string for the blob endpoint.
Justin Gould has provided the answer for rewrite everything to cdn/index.html
. Based on your scenario, I have tested my rule and it could work on my side.

QUESTION
I'm using "jQuery Query Builder"(in UI) to generate a custom Object based on user inputs and I need to feed this Object as the input of the "json-rules-engine"(in Server) to generate a Result based on the conditions in the object. But the problem is Query Builder gives output in a different format and the Rules Engine takes the input in some other format.
I'm able to iterate through all the nodes of the Object and get the "keys/values" respectively. But I'm not able to use those "values" in order to generate a new Object with different structure.

I'm trying to build a form with conditional fields from a JSON schema using react-jsonschema-form and react-jsonschem-form-conditionals.
The components I'm rendering are a FormWithConditionals
and a FormModelInspector
. The latter is a very simple component that shows the form model.
The relevant source code is:
...ANSWER
Answered 2018-May-09 at 16:19The problem is pretty straightforward, you are creating a FormWithConditionals
component in your render method and in your onChange
handler you setState
which triggers a re-render and thus a new instance of FormWithConditionals
is created and hence it loses focus. You need to move this instance out of render method and perhaps out of the component itself since it uses static values.
As schema
, uiSchema
and rules
are passed as props to the ConditionalForm
, you can create an instance of FormWithConditionals
in constructor
function and use it in render like this
