Ability to programmatically upload contours about microdraw

This is another example
test.json.zip

hmm makes sense.

so on annotation load, client calculates hash. on subsequent saves, client calculates hashes. If the hash is different, it sends to the server to be saved.

I think it should be implemented in microdraw.js and not in save.js.
Perhaps with a new method, something like getUnsavedAnnotations() which returns (or resolves) all annotations with hashes different to the previous save.

This could also solve a widely requested feature in our institute: showing which annotation are modified, and show warning if user is about to navigate away.

[r03ert0]

the getUnsavedAnnotations idea is good!
I merged a PR for the programmatic upload. I haven't removed the hash stuff yet.

(i'll close the issue, because of PR #187 , but we can keep the discussion here)

[xgui3783]

commit looks great.

Curious as if req.body.action is still needed? we could simplify the code a lot.

[r03ert0]

it's true. It's kind of redundant with upload

@xgui3783 ? How and where would you add tests for the functions inside /api/index.js?
I have, for example, this one:

    it('should detect a proper annotation object as such', (done) => {
        const ann = [{annotation:{path:[
            "Path",
            {applyMatrix:true,segments:[[10,10],[20,20]],closed:true,fillColor:[1,0,0,1],strokeColor:[0,0,0],strokeScaling:false}
        ],"name": "Test"}}];
        assert(validateAnnotation(ann)).to.be.true;
        done();
    });

testing saveFromAPI ?

Hmm my approach would be changing

const saveFromAPI = function () {}

to

const saveFromAPI = function () {}
exports.saveFromAPI = saveFromAPI

then one can import the function like this:

const { saveFromAPI } = require('./api/index.js')
