AJV taking too long for compile schema

Hi, i am using ajv for validate huge jsons.

I’m parsing 1000 lines to json and sending to ajv.compile but is taking about 30,40 secons to compile, it is normal take too long?

I used to had this working fine, but since last weekend the compile is almost impossible to use. I’ll post my method of validation , if it is something wrong please tell me, i dont know what to do anymore. `export function validateSchema( arrayJson: Array<iSchema>, schema: any, file: Files, maxErrors: number, numErrors: number, callback: Function ) { Arrayerror = []; let teste = 0; try { for (var values of arrayJson) { if (numErrors >= maxErrors) { break; } const ajvTeste = new Ajv({ strict: false, allErrors: true, }); require(“ajv-keywords”)(ajvTeste); addFormats(ajvTeste); AjvErrors(ajvTeste);

  let validate2 = ajvTeste.compile(schema);

  if (validate2(values)) {
    teste++;
  } else {
    ErrorFields =
      validate2.errors &&
      validate2.errors?.map((vals) => {
        return vals.dataPath;
      });
  }

  if (ajvTeste.errorsText(validate2.errors) !== "No errors") {
    numErrors++;
    Arrayerror.push({
      line: values.seq,
      errors: ajvTeste.errorsText(validate2.errors).split(","),
      campo: Array.prototype.join.call(ErrorFields).split(","),
      file: file,
      layout: values.tabela,
      full_line_error: values.linha,
    });
  }
}
return callback(Arrayerror, numErrors);

} catch (e) { console.log(“w”); } }`

This depends on which frameworks you use and how your application is structured, Ajv doesn’t prescribe any specific steps other than API it exposes.

There are some recipes here: https://ajv.js.org/guide/managing-schemas.html
