It was a term invented by framework developers to infer that using their framework would magically create a RESTful application. Add a comment. Active Oldest Votes. In theory there is no difference, in practice some intermediary caches are configured to not cache representations that have query string parameters. The Overflow Blog. Does ES6 make JavaScript frameworks obsolete? Podcast Do polyglots have an edge when it comes to mastering programming That is exactly I will do in my application using Laravel if I have that similar case.
So I made a post API like this:. Pass required job request in the body. If a job name is known, pass it as the job-type. I have a question regarding the rest api. When I have a product and a pricing domain and want to search for a product priced by pricing, how do I determine the uri? For example, I have a product with an id of 1 and pricing policies A and B.
How do I get the uri to retrieve a product with id 1 priced through pricing A? Hey wonjin what about query parameter? I would think avoid second option as it as a verb and the recommendation is to avoid any verb or action. You are talking about the current team, then delete the user from the team. I would have an email field in the user table. If they have multiple emails, always designate one as primary. I will have a verification email as a different resource.
Hello, I am answering the second question. I think it would be more readable if you remove send- from the URI. My mentor advises me not to use verbs, but nouns. So the request will be:. For a set of product ids, pass them as query parameter to filter i. Is there any discussion of an API standards definition for base object classes? It would be nice if there was a universally recognized Person class that I could extend to meet my needs.
I have a question regarding naming of resource. If I want to fetch all the document-links in a document based on the type and version.
You can simplify it to links from document-links, as you want. A very good guide on naming! It is worth mentioning that hierarchical URLs may lead to problems if we possibly at a later stage want to enable filtering that span document-links of different document-ids. How can we represent such collection? We will not get support in standards like OpenAPI and in many server-side implementation frameworks you would have to do some workaround because it does not fit with out-of-the-box functionality.
Thank you for a very interesting article. One of the very few that talk about a controller archetype. Here is my question to you. You have a list of all courses available to the students for Fall This includes the course title, description, number of credits, pre-requisits … etc. At the same time, you want to access the courses for which a particular student has registered for fall Those would include the ID of the course, the grade, the grades for each homework, grades for each exam ….
Second URI: Grades belong to each student so they could be a collection under students. These are filtered by semester. Grades could also be their own collection maybe you want to get all grades for visualization? Hi there, Thanks for this rules list. I think, those aforementioned conventions are enough, so as to comply with uniform interface constraint.
The difference is to access secured resources, it must follow authentication mechanism which is a common practice. Excuse me, I have a question about hierarchical relationships. How to define the number of layers, whether the parameter in the path are counted as one layer.
I am curious to know why you want to count the number of layers in the URI. But, anyway, for the given case, there are 3 layers, as the forward slashes are used to define relationships. I think it is fair for the store archetype to use singular nouns.
It is not designed to be an access point for individual items in it, which means URL pattern like the following is not used in general:. In fact, in your later controller examples, you used singular nouns cart and playlist for store as well:. Nice catch on the two examples of controller resource. Hey, Regarding using query component to filter URI collection — how should I do it if I want only managed-devices that has region field exists?
Maybe you can use a specific parameter to denote that the parameter is to be used for region field existence, e. Great article thank you, I have a question for naming of resource: — There are two api in my project.
One of them is sending single message to my service. The other one sending multiple message to my service. How to naming of them correctly? Without understanding the whole use-case, it would not be correct to suggest appropriate naming.
It should be accept 1 to N messages. How to name Controller? Focus on resource naming. Servers must have the freedom to control their own namespace. Instead, allow servers to instruct clients on how to construct appropriate URIs, such as is done in HTML forms and URI templates, by defining those instructions within media types and link relations. Thanks for sharing your thoughts. It is right that URIs should be instructed to clients through hypermedia.
Or please share an example if there is a gap. Fielding confirms this in his dissertation: At no time whatsoever do the server or client software need to know or understand the meaning of a URI — they merely act as a conduit through which the creator of a resource a human naming authority can associate representations with the semantics identified by the URI. There are resources. A countably infinite set of resources bound only by restrictions on URL length.
Or not? Please, provide argumentation. Option 1. My question would be the reason why you have two URIs for the same resource? Use one of them. Query strings are meant to sort collections, not to get a single document. Option 1 cant work as the API wouldnt know which field to parse as.
Pick your identifier and stick with it. Ensure you have Node. Create a new package. Run npm install from the command line to fetch the dependencies, then create an index. The web service API code can therefore be changed to allow access from any client-side script running on any domain:. Alternatively, an Express. The success of REST owes much to its simplicity. All are valid options to fetch data for user The number of combinations increase further when you have more complex operations.
That can be difficult to achieve on large codebases with many developers. However, this increases the workload, as multiple APIs are maintained. Older APIs can eventually be scrapped, but the process requires careful planning.
The Joke API shown above is open : any system can fetch a joke without authorization. This is not viable for APIs which access private data or permit update and delete requests.
Yes, this is sometimes true. But not always. Blindly adding filtering and pagination strikes me as premature optimization. Conversely, if the expected collection size is large, or the normal use case is to want only a small subset of records, or design requirements state that you never want the consumer to be able to know the entire collection, then you should add these features.
In that sense, no service that returns structured data where the consumer needs to have a specific understanding of the structure is actually RESTful. But that ship has long since sailed.
JSON is a concise, fairly readable, widely used format for data persistence and transfer. The only rule is that you must state what the content is in the content-type header field.
The API call did, in fact, succeed our back-end code ran, computed a result, and returned it to the caller. Here are some of the problems in trying to specify best practices in this area:. But what if there is no department named deptID?
Bad Request or Not Found? Caching is a valuable and interesting topic. Absolutely not. Some problem domains are not amenable to caching. Still others will not benefit sufficiently from the extra complexity of caching to make the effort worthwhile.
JSON is not native to html but forms are. I disagree with your explanation of collections being plural or singular. You usually have on path for drilling down further into a resource.
Thank you for writing this response, I hope people who read this article get to read this comment as well! It reduces the cognitive load for users of the API. However, I think some commonly accepted conventions are needed to make the API easy to understand.
Really helpful, one aspect I think that is missing is good practice to structure your JSON data while accepting and responding. This article barely scratches the surface of REST, and there are some things mentioned that are debatable. I believe the one thing that is not debatable and is definitely just plain wrong, and very bad practice, is associating any of your design of your REST API with your underlying database.
You want to be able to change your database design without having to redesign your API. So not only is it wrong that you said you should model your API based on your database tables, you should go one step further and make sure you design your API completely independently of any database design. Could you give some example or at least point to a site where this concept is explained?
I appreciate your help in this matter. Separation of the code that does the querying from the code that handles API responses is how you achieve this. I would have avoided shooting my own leg a couple of times if I would have known the things listed in this one. Sad to see the article mention caching but not cache headers[1], error codes but not problem details[2], and nested resources but not hypermedia[3].
The advice that IS here seems solid though, and it would make the life of an API consumer much easier if it were consistently followed! If you are dealing with really large dataset, you should not filter results on the server but you should form appropriate query to the DATABASE, and the database should handle you filtered results that you can serve via your API.
Why on earth do you return req. I know, you want to read what you send, but this is not even logically correct. You could log sseparately for the body you sent but not putting it into response.
This is nonsense. When Express 4. The syntax then changed from app. You can use express. Some basic things are missing in this article which is essential now days e. Great article an even better comments. JSON with the proper header for response is also something that improved things.
All in all quite interesting. Having defined contracts answers many ambiguities as well as allows for clients to be autogenerated, making much of the conventions still desirable, but not as necessary especially for edge cases. Well, these express,. These are weird substnaces. The only Language of web is PHP. Why does the sort query string value contain two values delimited by comma.
You can have multiple query string values eg. I suppose there are some reasons to process on the server side, for example turning a date of birth into an age so nobody sees it. Any thoughts?
