feature: Implement request transformation between HAR and Firecamp formats

[Nishchit14]

Description:

Firecamp currently does not have the ability to transform HTTP request/response data between the HAR (HTTP Archive) format and Firecamp's internal request format.

This feature request is to implement bidirectional conversion:

• [ ] HAR to Firecamp request: Parse a HAR request object and convert it to a Firecamp request object
• [ ] Firecamp request to HAR: Take a Firecamp request object and convert it to a HAR request object

This will allow:

• Importing HAR files from other tools (like browser developer tools) into Firecamp for editing/replay
• Exporting requests edited in Firecamp out to HAR format for use in other tools
• Prepare a code snippet for the request

The implementation should include:

• Mapping of all relevant fields between the two formats
• Helper functions for HAR -> Firecamp and Firecamp -> HAR conversions
• Unit tests validating bidirectional conversion

This feature will enable better interoperability with external tools for importing and exporting HTTP request data.

Hey @Nishchit14 would like to contribute , though I have not much knowledge about the above issue.

[Nishchit14]

The business logic of this feature is around HAR and Firecamp API Request transformation. Firecamp Rest Request and HAR both have JSON format. We need to create two transformer functions

Converts formats

1. HAR Request to Firecamp Rest Request
2. Firecamp Rest Request to HAR Request

Getting started steps would be

1. create a new package under the packages/*, folder name firecamp-har and package name in package.json with @firecamp/firecamp-har, you can copy the existing package to start with typescript boilerplate
2. start building transformer business logic
3. write jest tests
4. submit PR.

for any kind of help feel free to ask on Discord's contribution channel.

@note: only transform request to request, do not consider whole collection transformation as of now.

@Nishchit14 are you asking to implement a toll to convert a har to fire format and vice verse?

[Nishchit14]

@jatingodnani yes, format conversion from HAR to Firecamp and Firecamp to HAR.

[jatingodnani]

@Nishchit14 where to implement this

[Nishchit14]

@jatingodnani please read this https://github.com/firecamp-dev/firecamp/issues/115#issuecomment-1767796283, specific this section Getting started steps would be

[jatingodnani]

@Nishchit14 can you pls tell me is this correct?or i am missing something

[jatingodnani]

@Nishchit14 check this above

[Nishchit14]

@jatingodnani Refer this https://github.com/firecamp-dev/firecamp/pull/120#issuecomment-1770504239

I appreciate your efforts to understand this issue. I need some time to prepare a minimum package so you can start. also the HAR <=> Firecamp comparison looks good at first sight but I prefer to have json in PR so I can review it properly.

[jatingodnani]

@Nishchit14 can you pls checkk and review is it correct conversion

[Nishchit14]

@jatingodnani yes, it looks correct.

[jatingodnani]

@Nishchit14 i am ready to take this issue.
