PiriConfigurable Data Mapping for mortalsDocumentation
(Stable|Latest) |Source Code|Task TrackerWhat is PiriPiri is a JSON to JSON mapper. That means that we read input JSON and create output JSON. How the output is created is based on instructions from a configuration file. The configuration file governs the the output structure and tells piri where in the input to find data and where to place it in the output. In addition to this Piri supports data transformation withdata casting,if conditions,combination of data from multiple placesand of course settingdefaultvalues.This enables you to change any input into the output you desire.Typical usecasesYouGETdata from api, but need to transform it for your backend systemPOSTing data to an api that needs data on a different format than what your system producesAll your backends speak different language? pipe it throughPiriCustomer delivers weirdly formatted data? UsePirito make it sexyHave CSV but need nicely structured JSON? make CSV into a JSON list and transform it withPiriHave XML but need to change it? make it into JSON, transform it withPiriand then dump it to XML again.Customers legacy system needs CSV. UsePirito transform your nicely structured JSON data into a JSON List that can be easily dumped to CSVOfficial Open Piri Solutionspiri-cli, commandline interface for file to file mapping.piri-web, One Click deploy Web REST API for Piri JSON mapping.Enterprise solutionsComing...GoalThe goal of this library is to make JSON to JSON transformation/mapping easy, configurable and documentable. We achieve this by using a simple but feature-rich JSON configuration which then also acts as documentation and as a contract between parties.WhyPiri was born because we really dislike mapping. Documenting whatever decisions made in your code so that some product owner understands it is alsono me gusto. Transforming data from one format to another is something software engineers do allmost daily... It should be easy! And documenting it shouldn't be something you have to worry about.After the Worst POC in History we never wanted to do mapping by scripts and code again. This lead to the idea that it should be possible to create a file which governs how the structure should look and how the data should be transformed. This would then be thesingle source of truthand with Piri we have achieved this.We believe that this will make collaboration between teams faster and easier. Use Piri to agree with data formats between Front-end and Back-end. Between the 3rd party system and your back-end. You can even use Piri for testing existing integrations ;-)FeaturesMapping with configuration File.JSON Schemavalidation of the config file.Structurally Transform JSONCombine multiple values to one.Default valuesIf statementsis, contains, notcastinginteger, decimal, iso dateContributingPlease seecontributeInstallationPackage is on pypi.
