Graphql regex

Out of the box, GraphQL supports validating your inputs based on type information. For example, you can ensure that an argument is a particular scalar type, such as String or Int.

You can also enforce the shape of object arguments using input object types. The above enforces all fields are strings, and ensures they are not null. This means providing a field greater than characters will cause an error! Today, people most commonly write this kind of validation logic in their resolver functions or models.

This module exposes a constraint directive to decorate an SDL with validation rules. A full example can be found on the graphql-constraint-directive readme. More complex validation rules, such as those which rely on state e. In this case, as it's a string, the option of defining a format can be used. This particular constraint is validating that the value is an email address and it's characters at most.

Another way to write this could be to split it into multiple constraint directives. Note that directives are resolved right to left. For example, maxLength would be resolved before format in the following field definition: email: String!

On a different field, it is confirming the last name is a maximum of characters and also matches a regular expression. In this instance, alphanumeric only sorry double barrelled surnames! You could remove maxLength and perform this check within the expression. However, regex and. When a consumer sends a request which breaks these rules, the application will respond with an error message. If you wish to provide your own message, you can do that within the formatError option to Apollo Server.

Specifically, it says Expected type ConstraintStringeven though the field is defined as String! The constraint directive wraps each field with its own scalar type. When the value of each decorated field is parsed, the validation rules are executed.

This allows wrapped scalars to execute their own parseValue function, enabling support for custom scalar types! You can look at the code of graphql-constraint-directive as an example! To publish a custom directive as a module, ensure the custom directive class is exported as the main module entry.

I hope this inspires you to develop and publish your own custom directives! Sign in.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

This seems to run counter to the specwhich doesn't allow hyphens in names. Can you clarify what your intentions are here? This is a pretty treacherous way to allow a hyphen, buried in the middle like that.

Would be better to put the hyphen at the very beginning or end of the range; eg:. As wincent mentioned, this change would break compliance with the spec. Dashes are intentionally not supported as they're not valid characters in identifiers in most modern languages, and GraphQL is designed to be useful alongside as many different environments as possible. I would suggest creating an issue or PR against swagger-to-graphql in order to support swagger fields with characters outside of those supported by GraphQL field names.

Is there some place to discuss this restriction, or propose something more flexible? The interoperability story makes alot of sense from a platform implementation standpoint. However, it's severely limiting when trying to do interoperability with any real life existing data schemas especially json.

GraphQL queries always return predictable results. GraphQL queries access not just the properties of one resource but also smoothly follow references between them. Access the full capabilities of your data from a single endpoint. Know exactly what data you can request from your API without leaving your editor, highlight potential issues before sending a query, and take advantage of improved code intelligence. Aging fields can be deprecated and hidden from tools.

I want to add a field 'dmcSearch' to filter using a regex expression. Where can I start? I have been trying with something like:.

Your issue inspires me to simplify this process and create a declarative method for adding a filter to the resolver cause it's the common task for graphql-composer. Oh, if you don't use Relay wrapper, then your path should be: ViewerTC. So undefined returned if by this path is nothing exists. Can you provide screenshots from graphiql of Viewer type. I suppose that field dmcList does not have any args or has different name. Sure, here's the viewer, the dmclist and the filter:.

According to your screenshots code above should work. Maybe I am missing something. In the following code: resolveParams. In my case 'name'. Step 1: Extending resolve method of dmcList field. All args that exist in args. So you may change args. For your case, we removing regex from the query and add name. Be sure that Step 1 runs before Step 2because on the first step we also adding dmcList to the Viewer type. Otherwise ViewerTC. Step 2: adding field to InputType in args dmcList has args, one of them is filter.

So we adding field to it with name regex. Hi again, it still returns the error described before. Maybe if you can provide a working example. If not we can close this.

Also lexer can use the cache to save on memory allocations for named tokens in the managed heap:. By default the cache is not used. You can find some results of testing with and without the cache in this file. Keep in mind that the advantages and disadvantages of using the cache appear depending on the specific usage scenario, so it is strongly recommended that you obtain some metrics before and after using the cache to ensure that you achieve the desired result.
