Learn how to incorporate SAX parser into an Angular 2 project by utilizing TypeScript

Encountering challenges while trying to integrate the sax parser [parser.ts] into my project.

import sax = require("sax");
export class MyParser {
   //my parser code 
}

When attempting to utilize it [app.component.ts]:

import {MyParser} from './parser'
...
constructor(private http: Http, private parser: MyParser) {}

An error surfaces:

Evaluating http://localhost:3000/sax

This indicates that SystemJS is unable to locate the module. Despite sax being installed in node_modules and outlined in package.json. Typings were acquired using

typings install --ambient sax

However, numerous duplicate identifier warnings persist even though my tsconfig.json excludes

"exclude": [
  "node_modules",
  "typings/main",
  "typings/main.d.ts"
]

In his examples, isaacs employs code such as this

 tag.parent
tag.children

This functionality isn't supported by the typing (d.ts).

If anyone has successfully implemented sax with TS and ng2, your insights would be greatly appreciated!

Answer №1

It seems like the issue you're encountering is occurring during runtime. One potential solution is to adjust the configuration of SystemJS as follows:

<script>
  System.config({
    paths: {
      sax: './node_modules/sax/lib/sax.js'
    }
  })
</script>

By making this adjustment, you should now be able to successfully import Sax using the following code:

import {SAXParser} from 'sax';
