Utility functions for using Joi without using Joi.
Joiless lives on npm, so just install it via the command line and you're good to go.
$ npm install --save joi joiless
You need to install
joi itself as this module does not include it as a production dependency (so you can use your own
joi version). If you try a version which has an issue caused by the module, please file an issue.
Here's an example (both of these are identical, and are in fact a test case in this repo):
const Joi = ;const Joiless = ;// Joi versionlet joiSpec = Joidescription'The date (in milliseconds) that this crash last appeared';// Joiless versionlet joilessSpec = Joiless;
The translation is simple; the key is the function called on the Joi chain, and the value is the value passed into the Joi chain call.
- If you pass an Array as a value, it's applied to the Joi function - if you wish to pass an Array as an argument, use
[ [ <your_array> ] ].
- If you want to call a function with no arguments, either pass
undefinedas the value, or you can use the
afterhook (whichever you prefer):
const Joiless = ;// via undefinedJoiless;// via afterJoiless
Attaching Child References
If you make a complex schema, you can use
attach to hook the child keys onto the parent.
For example, in the snippet below you can reference
Record.Username to pull back the username spec. This is done using
get, it doesn't store the value twice.
const Joiless = ;// define the specconst Record = Joiless;// attach the childrenJoiless;
Sometimes you wish to define a base schema, and then extend it to override some of the parent stuff. Naturally, the
spec API doesn't fit here, so I added an
Extension is easy, you just pass the schema to extend as first arg, and your spec overrides in the second argument.
const Joi = ;const Joiless = ;// define the base speclet base = Joiless;// define our extensionlet extended = Joiless;// run validationJoi; // failsJoi; // passes
