Library and API to calculate CO2 emissions for personal mobility.

maasglobal, updated 🕥 2022-12-08 10:56:27

Sustainable Mobility API

This project consists of a Python library and HTTP API for estimating the environmental impact of personal mobility.

Estimator

The estimator consists of a Python library to calculate CO2 emissions for a transport trip based on the distance and mode. The library has been published to the Python Package Index as transport-co2.

The README in the estimator folder also have examples on the library responses, for various modes of transportation.

API

The API provides an HTTP(s) endpoint to estimate the CO2 emissions for a transport trip. Internally, the API relies on the "transport-co2" estimator library.

Please go into api folder to read more about running locally or deploying as docker container or serverless function.

Roadmap

This project is intended as a proof-of-concept and to generate feedback for future development. See our project roadmap for upcoming plans and ideas.

Bump jszip from 3.2.2 to 3.10.1 in /api

opened on 2022-09-08 12:28:51 by dependabot[bot]

Bumps jszip from 3.2.2 to 3.10.1.

Changelog

Sourced from jszip's changelog.

v3.10.1 2022-08-02

  • Add sponsorship files.
    • If you appreciate the time spent maintaining JSZip then I would really appreciate your sponsorship.
  • Consolidate metadata types and expose OnUpdateCallback #851 and #852
  • use const instead var in example from README.markdown #828
  • Switch manual download link to HTTPS #839

Internals:

  • Replace jshint with eslint #842
  • Add performance tests #834

v3.10.0 2022-05-20

  • Change setimmediate dependency to more efficient one. Fixes Stuk/jszip#617 (see #829)
  • Update types of currentFile metadata to include null (see #826)

v3.9.1 2022-04-06

  • Fix recursive definition of InputFileFormat introduced in 3.9.0.

v3.9.0 2022-04-04

  • Update types JSZip#loadAsync to accept a promise for data, and remove arguments from new JSZip() (see #752)
  • Update types for compressionOptions to JSZipFileOptions and JSZipGeneratorOptions (see #722)
  • Add types for generateInternalStream (see #774)

v3.8.0 2022-03-30

  • Santize filenames when files are loaded with loadAsync, to avoid "zip slip" attacks. The original filename is available on each zip entry as unsafeOriginalName. See the documentation. Many thanks to McCaulay Hudson for reporting.

v3.7.1 2021-08-05

  • Fix build of dist files.
    • Note: this version ensures the changes from 3.7.0 are actually included in the dist files. Thanks to Evan W for reporting.

v3.7.0 2021-07-23

  • Fix: Use a null prototype object for this.files (see #766)
    • This change might break existing code if it uses prototype methods on the .files property of a zip object, for example zip.files.toString(). This approach is taken to prevent files in the zip overriding object methods that would exist on a normal object.

v3.6.0 2021-02-09

  • Fix: redirect main to dist on browsers (see #742)
  • Fix duplicate require DataLengthProbe, utils (see #734)
  • Fix small error in read_zip.md (see #703)

v3.5.0 2020-05-31
