fs.readFileSync is not a function

[Fayde]

Recently updating my angular dependencies to angular cli 1.1.1 and related packages to 4.2.2 and this is being thrown from mime.js, any ideas because i'm lost

I assume this is browser-side code, where the fs module is just shimmed with an empty object (or whatever).

That error is probably coming from mime's legacy support for the mime#load() method, here. I left that method in when I switched from reading the Apache configuration file to, instead, use the mime-db dataset (as types.json). This code was never really intended to be run in the browser, but apparently some module somewhere is trying to call into it...?

Easy way to identify the culprit is to edit your node_modules/mime/mime.js file and throw a console.trace() statement in there and see what shows up.

Can you think of any fix for this? I need to use the intimidate package for uploading a Buffer to S3, and it requires mime.

I'm also getting the error, and can't seem to find anywhere where mime#load() is called. I do see placed where mime#lookup() is called. Is lookup() vulnerable to the same issue?

[aarohmankad]

Okay so it seems mime itself is calling mime#load(). Is there any alternative method of writing the following piece of code that will allow mime to run in the browser?

@aarohmankad try doing npm install mime@latest. intimidate depends on "mime@^1.2.9". Forcing npm to install the latest version (which doesn't call mime.load() during initialization) may fix this issue.

@broofa It does fix the issue! I submitted a PR to intimidate to upgrade the mime version. Don't think it will be merged anytime soon though. (Last commit was 2015.)
