Use async/await

[ai]

Logux Server 0.3 requires Node.js >= 10, so we are safe to use async/await instead of Promise

[ai]

Part of the works was done in #58

@chafilin can you show me links to the code, where you have problems in replacing Promise?

[ai]

@chafilin don’t forget about tests. They are the main users of .then.

This kind of Promises:

server/bind-backend-proxy.js

Line 106 in b47dccd

processing[meta.id] = new Promise((resolve, reject) => {

server/bind-backend-proxy.js

Line 42 in b47dccd

return new Promise((resolve, reject) => {

[ai]

Yeap. Let’s keep Promise in those 2 examples.

I am waiting for PR to replace then in tests.

The current list of .then in project

➜ rg "\.then"
server-client.js
275:      .then(result => {

base-server.js
388:        .then(() => Promise.all(before))

405:    promise = promise.then(() => {
410:      promise.then(() => {
420:    return promise.then(() => {
424:    }).then(() => {

960:            }).then(() => emitSubscribed())
964:        }).then(access => {

580:  app.destroy().then(() => {

46:    let processing = delay(500).then(() => {
50:      processing = processing.then(() => {
52:      }).then(() => {
58:      }).then(() => {
62:      processing = processing.then(() => {
64:      }).then(() => {
68:    processing.then(() => {

Seems like we have only a few lines to close this issue.

What is the reason for the forcePromise module? You can await promises and non-promises.

[ai]

API was created before await.

Good idea to remove it. Do you want to send PR?

[uncaught]

Hmm, I would, but one test fails and I don't know why.
The test reports about errors during channel authorization has this assertion:
expect(test.names).toEqual(['add', 'clean', 'error', 'add', 'clean'])
But test.names is ['add', 'error', 'add', 'clean', 'clean'] without the forcePromise.

1. I forgot to say you send PR to v0.6 branch instead of master
2. You can find reports content in test.reports. Comparing `test.reports before and after changes could help you with finding a difference. It is OK if the content is the same, but only the order was changed.
3. If it will become too complicated you can send failing PR, I will help with tests.
