ajv: Module not found: Error: Can't resolve 'nodent' when used in Angular 2 project (browser)

What version of Ajv are you using? Does the issue happen if you use the latest version? 4.8.0

Your code (please use options, schema and data as variables):

import * as Ajv from 'ajv';

... ...  ...

@Injectable()
export class ValidationService {
  ajv: Ajv.Ajv;

  constructor() {
      this.ajv = Ajv({ allErrors: true, verbose: false });
  }

  public validateSettings(settingsSchema: JsonSchema, settings: SettingsData): ValidationResult {
    let valid = this.ajv.validate(settingsSchema, settings);
    return {
        valid: valid,
        errors: this.ajv.errors
    };
  }
}

If I run this in chrome I get:

Module not found: Error: Can’t resolve ‘nodent’ in ‘/MyProject/projects/client/node_modules/ajv/lib’ resolve ‘nodent’ in ‘/MyProject/projects/client/node_modules/ajv/lib’ Parsed request is a module using description file: /MyProject/projects/client/node_modules/ajv/package.json (relative path: ./lib) Field ‘browser’ doesn’t contain a valid alias configuration after using description file: /MyProject/projects/client/node_modules/ajv/package.json (relative path: ./lib) resolve as module /MyProject/projects/client/node_modules/ajv/lib/node_modules doesn’t exist or is not a directory /MyProject/projects/client/node_modules/ajv/node_modules doesn’t exist or is not a directory /MyProject/projects/client/node_modules/node_modules doesn’t exist or is not a directory /MyProject/projects/node_modules doesn’t exist or is not a directory /MyProject/node_modules doesn’t exist or is not a directory /Users/mmc/repos/node_modules doesn’t exist or is not a directory /Users/mmc/node_modules doesn’t exist or is not a directory /Users/node_modules doesn’t exist or is not a directory /node_modules doesn’t exist or is not a directory looking for modules in /MyProject/projects/client/node_modules using description file: /MyProject/projects/client/package.json (relative path: ./node_modules) Field ‘browser’ doesn’t contain a valid alias configuration after using description file: /MyProject/projects/client/package.json (relative path: ./node_modules) using description file: /MyProject/projects/client/package.json (relative path: ./node_modules/nodent) as directory /MyProject/projects/client/node_modules/nodent doesn’t exist no extension Field ‘browser’ doesn’t contain a valid alias configuration /MyProject/projects/client/node_modules/nodent doesn’t exist Field ‘browser’ doesn’t contain a valid alias configuration /MyProject/projects/client/node_modules/nodent doesn’t exist .ts Field ‘browser’ doesn’t contain a valid alias configuration /MyProject/projects/client/node_modules/nodent.ts doesn’t exist .js Field ‘browser’ doesn’t contain a valid alias configuration /MyProject/projects/client/node_modules/nodent.js doesn’t exist [/MyProject/projects/client/node_modules/ajv/lib/node_modules] [/MyProject/projects/client/node_modules/ajv/node_modules] [/MyProject/projects/client/node_modules/node_modules] [/MyProject/projects/node_modules] [/MyProject/node_modules] [/node_modules] [/MyProject/projects/client/node_modules/nodent] [/MyProject/projects/client/node_modules/nodent] [/MyProject/projects/client/node_modules/nodent] [/MyProject/projects/client/node_modules/nodent.ts] [/MyProject/projects/client/node_modules/nodent.js] @ ./~/ajv/lib/async.js 116:26-48 @ ./~/ajv/lib/ajv.js @ ./src/app/shared/services/validation-service.ts @ ./src/app/app.module.ts @ ./src/app/index.ts @ ./src/main.ts @ multi main

5.0.1-beta.3 should resolve it, finally

@epoberezkin I discover something interesting. There is no warnings, if I type require path as variable instead of string.

There is strings from async.js and compile/index.js

      var regeneratorPath = 'regenerator';
      regenerator = require(regeneratorPath);


    var nodentPath = 'nodent';
    if (!nodent) nodent = require(nodentPath)({ log: false, dontInstallRequireHook: true });


    var jsBeautifyPath = 'js-beautify';
    try { beautify = require(jsBeautifyPath).js_beautify; }

Yes, sounds like the same workaround. I hope my more detailed outline of a solution can help other people though. On the long run it would be wonderful if Ajv works as is (with typescript) with angular 2 and other new web frameworks.

But thanks for your support in fixing this - it is nice to experience an OS project with such an impressive responsiveness on issues. Thanks.
