ClassificationFS API

API definition

https://storage.googleapis.com/pint-internal-static-hosting/classificationFS/docsCLFS.html

Use in your app along with other tools:

const APIdefinition = require("classificationfs/APIdefinition");

Installation

npm install @naugtur/classificationfs

ClassificationFS SDK

Usage

const CLFSSDK = require("classificationfs/sdk");
CLFSSDK.use(options);

options

option	description
router	an express router to add the app to
protocol	optional, defaults to "https"
handlers	an object with handlers implementing operations on CLFS, see below for details
fileStreamErrorHandler	a function to call when file content streaming errors out. signature: (err, req, res)
authorization	an object related to Egnyte Protect oAuth process, see below for details
flags	a map of boolean flags to be returned in discovery
basePath	optional - if the router is mounted on a certain path, pass it here so that url generation tools work correctly

handlers

You must implement at least getDiff or getFolder. To generate URLs to subfolders in getFolder, use req.helpers.folderURL - it'll generate URLs pointing to the same folder endpoint with the id you choose to pass coming in as a param. If getDiff or getFolder returns external file content URLs, that's all. Otherwise, getFile needs to be implemented to return the file stream and you can use req.helpers.fileURL to generate those URLs when listing folders. report defaults to just console-logging the request body of the report. If you need something else, provide an implementation.
cleanUp handles a request coming in from Egnyte when the source gets removed - it's optional and can be used to clean up any mappings or data.

getDiff,getFolder,cleanUp and report return:

{
  body: JSON; //optional
  headers: {
  } //optional
}

getFile returns:

{
    stream: file content stream reference //required
    headers: {} //optional
}

helpers

req passed to the handler has an additional non-standard field helpers with the following:

folderUrl({ id }) => APPURL/fs/${id}
fileUrl({ id }) => APPURL/download/${id}
discoveryUrl({ storageId }) => APPURL/${storageId}
buildURL(anythingAtTheEnd) => APPURL/${anythingAtTheEnd}

Scaffolding of an app

const CLFSSDK = require("classificationfs/sdk");
const express = require("express");

const app = express();

const { router, startAuth, getUrlHelpers } = CLFSSDK.use({
  router: express.Router(),
  authorization: {
    oauthCredentials: {
      clientId: "CLIENT_ID",
      clientSecret: "CLIENT_SECRET",
    },
    onError: ({ error, res }) => {
    
    },
    tokenReceiver: ({ token, authProcessId, res, helpers }) => {
    
    }
  },
  handlers: {
    async getFolder(req) {
      const id = req.params.folderId;

      req.helpers.folderURL({id:"someother folder id"})
      req.helpers.fileURL({id:"someother file id"})

      return { body: JSONbody };
    },
    async getDiff(req) {
      const cursor = req.query.cursor;

      req.helpers.fileURL({id:"someother file id"})

      return { body: JSONbody };
    },
    async getFile(req) {
      const id = req.params.fileId;
      return {
        stream: storage.createReadStream(id),
        headers: {
          "content-type": "application/octet-stream",
          "content-disposition": "attachment"
        }
      };
    }
    async report(req) {
      console.log(req.body)
    }
  }
});
app.use(router);
app.listen(1337);

Mock server

npm install -g @naugtur/classificationfs
classificationfs-mock 8080

OR

npx -p @naugtur/classificationfs classificationfs-mock 8080

Port number is optional, defaults to 3000

I need it to be HTTPS

The best way to go is to expose the mock via ngrok. Install ngrok and run

ngrok http 3000

it will proxy your http server over to a https URL.

Working with the repository

To run mockserver from repository, just do:

node mockserver/cli.js

Edit the API definitions in their respective folders

install node.js for tooling to work, then run npm install in the repo folder.

run npm start to generate html docs run npm test to validate if the definition is syntactically correct.
