काम नहीं कर रहा है मैं अपने कोणीय 2 चश्मा चलाने के लिए कर्म-वेबपैक का उपयोग कर रहा हूं।कर्म वेबपैक स्रोतमैप

https://github.com/webpack/karma-webpack

जब मैं क्रोम में कर्म का उपयोग कर परीक्षण को अंजाम, मेरी ऐनक के लिए स्रोत फ़ाइलें डीबगर में पठनीय दिखाई देते हैं। हालांकि, परीक्षण फाइलों के तहत सिस्टम (मेरा आवेदन स्रोत) अपठनीय है।

मैं कर्म-स्रोतमैप-लोडर का उपयोग कर रहा हूं और निर्देश के अनुसार devtool 'इनलाइन-स्रोत-मानचित्र' पर सेट है। इस समस्या का कारण क्या हो सकता है?

यह बिल्ड AngularClass कोणीय 2-वेबपैक-स्टार्टर के बाद मॉडलिंग किया गया है। डीबगर में https://github.com/AngularClass/angular2-webpack-starter

यह मुद्दा istanbul-instrumenter-loader से आता है।

एक समाधान घड़ी मोड में परीक्षण चलाते समय कोड कवरेज उपकरण को छोड़ने के लिए कर्म और वेबपैक को कॉन्फ़िगर करना है।

अब, आप स्रोत टाइपप्रति फ़ाइल देख सके, जब npm run watch:test चल रहा होना चाहिए।

मैंने इन फ़ाइलों को अद्यतन किया है और निम्न त्रुटि प्राप्त करें: कॉन्फ़िगरेशन फ़ाइल में त्रुटि! [सिंटेक्स त्रुटि: ब्लॉक-स्कोप्ड घोषणाएं (चलो, कॉन्स्ट, फ़ंक्शन, कक्षा) अभी तक सख्त मोड के बाहर समर्थित नहीं है] सिंटेक्स त्रुटि: ब्लॉक-स्कोप्ड घोषणाएं (चलो, कॉन्स्ट, फ़ंक्शन, क्लास) अभी तक सख्त मोड –

यह this Stack Overflow question की तरह एक बहुत लग रहा है, और इसलिए यह वास्तव में एक ही समाधान हो सकता है।

वेबपैक, डिफ़ॉल्ट रूप से, वेबमाक को कर्मा तक पास नहीं करता है जब तक कि फ़ाइल एक्सटेंशन .js (या .jsx यदि आप प्रतिक्रिया का उपयोग कर रहे हैं)। इस तरह के सेटअप में, कर्म + वेबपैक सीधे टाइपस्क्रिप्ट से जावास्क्रिप्ट तक .ts फ़ाइलों (या .tsx) को सीधे ट्रांसफ़ाइल करता है और उन्हें उसी फ़ाइल नाम के अंतर्गत कार्य करता है।

मुझे एक समाधान मिला जो मेरे लिए on the GitHub Issues page for karma-webpack काम करता था। यह चाल वेबपैक कॉन्फ़िगरेशन में एक विस्तृत फ़ाइल फ़िल्टर के साथ webpack.SourceMapDevToolPlugin इंजेक्ट करना है। आपके लिए, ऐसा कुछ दिखना चाहिए:

var webpack = require('webpack'); 
// in your config.set: 
plugins: [ 
    // existing plugins go here 
    new webpack.SourceMapDevToolPlugin({ 
    filename: null, // if no value is provided the sourcemap is inlined 
    test: /\.(ts|js)($|\?)/i // process .js and .ts files only 
    }) 
] 

यह कोशिश करें और देखें कि यह समस्या को ठीक नहीं करता है या नहीं।

यह कोणीय 2-वेबपैक-स्टार्टर के साथ काम नहीं करता है, नतीजा यह है कि devtools में किसी भी स्रोत फ़ाइलों को देखने की क्षमता पूरी तरह से दूर हो जाती है (वेबपैक: // चला गया है) –

यह काम करता है। वेबपैक सामान को स्थानीयहोस्ट से उस 'बेस' निर्देशिका में ले जाया गया है, लेकिन इसे वर्कस्पेस में जोड़ने के बाद इससे कोई फर्क नहीं पड़ता। सबसे महत्वपूर्ण बात यह है कि काम टूटना! (कोणीय 4.3.6) –
