[info-arnav]

This PR adds a plugin directory with a basic dot-env support plugin.

I am not sure on how to go about it further. But provides a basic program in the plugin directory.

We need something like https://github.com/mrsteele/dotenv-webpack, just rewrite it on using cache (i.e. inputFileSystem) and more refactor

[info-arnav]

I have made some changes, add the caching to internal file system and refactored everything a bit

[alexander-akait]

It should be a plugin, no need to modify webpack-cli code

#3759

[info-arnav]

please ask more if you do not understand, the previous version was more correct

so, shall i rever it back to synchronous running and then make the changes suggested ?

[info-arnav]

@alexander-akait I tried to make changes, but like if i am using async then the tests arent executing and even the environment hooks are failing. Shall i make the other chaneges u said and revert stuff to a synchronous manner ?

[info-arnav]

@alexander-akait I have a asynchronous version as well, please let me know if i should upload that as well, if that is a major requirment.

[info-arnav]

@alexander-akait can you please guide me on where to get the types for the logger. For input file system the type can not be used as we are using readFileSync

[info-arnav]

@alexander-akait can you please guide me on where to get the types for the logger. For input file system the type can not be used as we are using readFileSync

please let me know about the hook also, as using initialize will remove the compilation object. so compilation.errors.push and compilation.cache wont work

@alexander-akait at line 58 I tried adding a

compiler.hooks.compilation.tap

inside the

compiler.hooks.initialize.tap

does that make sense ?

[info-arnav]

Also do you think adding a readFile in the compilation hook and SyncReadFile in the initilize hook makes sense ? As in we check if the compilation object was passed as an argument, if it was we proceed in an asynchronous way, else synchronous
