# Postman collection converter
Convert your Postman collections into different formats.
Very fast.
Offline.
Without 3rd-party dependencies.
These formats are supported for now: `http`, `curl`, `wget`.
> This project was quickly written in my spare time to solve one exact problem in one NDA-project, so it may
> contain stupid errors and (for sure) doesn't cover all possible cases according to collection schema.
> So feel free to propose your improvements.
## Supported features
* [collection schema **v2.1**](https://schema.postman.com/json/collection/v2.1.0/collection.json);
* export one or several collections (or even whole directories) into one or all of formats supported at the same time;
* all headers (including disabled for `http`-format);
* `json` body (forces header `Content-Type` to `application/json`);
* `formdata` body (including disabled fields for `http`-format; forces header `Content-Type` to `multipart/form-data`)
## Planned features
- support as many as possible/necessary of authentication kinds (_currently no ones_);
- support as many as possible/necessary of body formats (_currently json and formdata_);
- documentation generation support (markdown) with responce examples (if present);
- maybe some another convert formats (like httpie or something...);
- replace `{{vars}}` from folder;
- replace `{{vars}}` from environment;
- performance measurement;
- better logging;
- tests, phpcs, psalm, etc.;
- web version.
## Installation
```
composer global r axenov/pm-convert
```
Make sure your `~/.config/composer/vendor/bin` is in `$PATH` env:
```
echo $PATH | grep --color=auto 'composer'
# if not then execute this command and add it into ~/.profile:
export PATH="$PATH:~/.config/composer/vendor/bin"
```
## Usage
```
$ pm-convert --help
Postman collection converter
Usage:
./pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]
php pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]
composer pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]
./vendor/bin/pm-convert -f|-d PATH -o OUTPUT_PATH [ARGUMENTS] [FORMATS]
Possible ARGUMENTS:
-f, --file - a PATH to single collection located in PATH to convert from
-d, --dir - a directory with collections located in COLLECTION_FILEPATH to convert from
-o, --output - a directory OUTPUT_PATH to put results in
-p, --preserve - do not delete OUTPUT_PATH (if exists)
-h, --help - show this help message and exit
-v, --version - show version info and exit
If both -c and -d are specified then only unique set of files will be converted.
-f or -d are required to be specified at least once, but each may be specified multiple times.
PATH must be a valid path to readable json-file or directory.
OUTPUT_PATH must be a valid path to writeable directory.
If -o is specified several times then only last one will be applied.
Possible FORMATS:
--http - generate raw *.http files (default)
--curl - generate shell scripts with curl command
--wget - generate shell scripts with wget command
If no FORMATS specified then --http implied.
Any of FORMATS can be specified at the same time.
Example:
./pm-convert \
-f ~/dir1/first.postman_collection.json \
--directory ~/team \
--file ~/dir2/second.postman_collection.json \
-d ~/personal \
-o ~/postman_export
```
### Notice
Make sure every (I mean _every_) collection (not collection file), its folders and/or requests has unique names.
If not, you can rename them in Postman or convert collections with similar names into different directories.
Otherwise converted files may be overwritten by each other.
## License

## Disclaimer
I'm **not** affiliated with Postman, Inc. in any way.
I'm just a backend developer who is forced to use this javascripted gigachad-shitmonster.
So the goal of this project is to:
* take the data and its synchronization under own transparent control;
* easily migrate to something more RAM tolerant and productive, easier and free to use;
* get off the needle of the vendor lock, strict restrictions for teams and not to pay incredible $$$ for heavy useless WYSIWYGs;
* give YOU these opportunities.
