This is a playground to test JavaScript. It runs a completely standard copy of Node.js on a virtual server created just for you. Every one of npm’s 300,000+ packages are pre-installed, so try it out:
const Ajv = require("ajv");
const ajv = new Ajv({
"allErrors": true,
"jsonPointers": true
});
require('ajv-errors')(ajv);
const schema = {
"type":"object",
"properties": {
"foo": {
"type":"string",
"if":{
"maxLength":5
},
"then":{
"enum":["bar"],
"errorMessage":{
"enum":"foo must be 'bar'"
}
},
"else":false,
"errorMessage":{
"_":"if-clause failed."
}
}
}
}
let validate = ajv.compile(schema);
console.log(validate({"foo":"baz"}));
console.log("Errors:",ajv.errorsText(validate.errors));
