Hash drive

problem statement

Ipfs is awesome , but is it really required to open a web browser to upload files into filecoin. what if there is only one command like git push git pull to upload and get files

Solution 💡

Hashdrive solves the problem, we provide a CLI tool that user can download and use it anywhere , in any directory or filepath to upload the file just with one command ,

features📃

command	Description	argument
-t	updating the web3.storage API token	API_Token
-u	upload file to web3.storage	filename
-d	download file	filename
-ls	list all file structures in present directory	-
-pwd	returns the present working directory	-
-cd	change directory	folder name

File structures

We have decided to upload only files into the web3.storage , and store the file structure in a data file .This was required for ls, cd and pwd commands , where we have to traverse through the file structure, Due to this there were huge conflicts on the file storage and retrieval process.

• A Data file to manage entire file structure , and the CIDs of all files was made using solidity smart contract , so that the CIDs are safe and can't be accessed by any attackers

commands with multiple arguments

since our solution is a CLI application , one of the major problem that we faced was the situation when user enter multiple commands and functionalities at once

• closely studied the commands that need to be mutually excllusive , and those that can be used together , and made the logical conditions to support all the possible and valid command inputs

Downloading the file

for downloading files from ipfs we just have a get function , as a result whenever we type the function we open a webbrowser , hence the file does not directly get download but opens a webpage , from which we have to download

• used window.location to downloiad the file directly without the browser

PowerShell says "execution of scripts is disabled on this system."

while installing package as a cli tool , powershell raised an error due to the insufficient permissions

• Running the following command solved the problem Set-ExecutionPolicy RemoteSigned -Scope CurrentUser here we have signed the execution policy for the existing user , thereby alowing node to install the cli tool stack overflow link
