Problem with requesting local files?

[guypursey]

I have noticed issues with using d3.request since moving my repository from D3 version 4.10.0 to version 4.10.2.

By examining my package-lock.json, I noticed one difference is that the former uses d3-request version 1.0.5 whereas the latter uses d3-request version 1.0.6.

The situation:

• I am using browserify and http-server to prepare and serve my file respectively.
• I have a file called index.html which I access via localhost:8080 when I'm building something.
• I have a file called filelist.json which I can access via localhost:8080/filelist.json while I'm building.
• I tried using d3.json() to access filelist.json from index.html and process the data.
• Initially I used error and data arguments in the d3.json() callback to throw any errors and start working with the data. However, I got an Unexpected token T at character 0 error.
• I removed the error throw and simply logged data in the console. This is when I saw that the T was the beginning of the line TypeError which was reporting that it could not access the file.
• The problem seems to be that d3.json() was attempting to access my file from the address localhost:80filelist.json, instead of the full and correct address.
• I tried this with other d3-request methods, like d3.tsv() and d3.request() itself. Same error thrown, albeit in slightly different guises depending on the function.

Since rolling back to D3 v4.10.0 I have not had this problem.

Duplicate of #24. Please see that issue for discussion on how to bundle D3 modules.

Thanks. Apologies for missing the previous issue on this. Will have a read.
