`When should I use it
ZodAccelerator is useful when the schema is used multiple times during the same session. The time to build the custom function is about twice as long as its execution. If you only need to call your schema once, it might not be the best solution.How does it work
The function allows you to create a custom function based on the schema passed as an argument. The function will be used to create an instance of the ZodAcceleratorParser object. This makes its usage similar to Zod's.`ts
zodSchema.parse(...)
zodAccelerateSchema.parse(...)zodSchema.parseAsync(...)
zodAccelerateSchema.parseAsync(...)
zodSchema.safeParse(...)
zodAccelerateSchema.safeParse(...)
zodSchema.safeParseAsync(...)
zodAccelerateSchema.safeParseAsync(...)
`$3
To build the custom function, we have created a converter for each type. Not all types are supported. However, to avoid compatibility issues, when a type is not supported, ZodAccelerator directly uses the Zod schema. To find out which types are supported, go to the folder.$3
The functions created by ZodAccelerator have some key differences compared to Zod's basic functionality :
- In case of an issue, the schema analysis does not continue, it stops immediately.
- Errors are not as explicit.
- All secondary parameters, such as custom messages, may not be implemented everywhere (can be done on request).
- The Zod contexts of zodEffect are not as complete.$3
For each type that Zod provides, we have an algorithm that translates the information from the Zod schema into a string of code. At the end, the different relevant parts are assembled and interpreted using the eval function (no injection possible).$3
Would it be possible to build the schemas in a file and then call them instead of rebuilding them? Unfortunately, no. The construction is mandatory because, in addition to the content, we also build its context (this). In the case of a ZodEffect` type, for example, the associated function is stored in the context. Therefore, skipping the construction phase is not possible.
