Nano is a minimalistic client for CouchDB

does nano uses promises?

hi guys

I’m trying to understand search

can I search a field for instances of a string and return the doc?

is that how that works?

logs: (thing, callback) => {
      nano.db.use(‘mydb').search('log', 'logs', { message: ’searchstring’}, (err, data) => {
      callback(err, data);
    });
  },

where I have a field in my logs view called message

Error: missing handler: _search

so I guess I am doing something wrong

hmm

@tnguyen14 @felixsanz nano does not support promises. There are several wrappers that do.

@tnguyen14

@mcrummey do you recommend any of them?

@mcrummey

I use https://github.com/romeovs/nano-promises and https://github.com/OlavHN/co-nano

Tri Nguyen

@tnguyen14

ok thanks, I'll take a look

@mcrummey

for promises and generators(async/await)

hello. i'm trying to understand nano tests. I don't have a JS background, but I note that nano uses a mock lib. How are the functions tested? Is it using a real couchdb, or mocking responses, etc. Thanks.

Matt Crummey

@mcrummey

Hey Raymond, it looks like they have both mocked and unmocked tests.

npm run mocked && npm run unmocked

"npm test" runs the unmocked tests

Speaking of testing… I’m looking for a simple way to check for the presence of a specific database in couch for a mocha test.. Any ideas? db.head? db.use() then something?

In https://github.com/dscape/nano/blob/master/lib/nano.js#L64, it looks like (.*)@ is used to match the text up until the first occurrence of @ instead of the non-greedy (.*?)@. Seems reminiscent of the recent Lastpass vulnerability (e.g. https://foo:bar@host/foo/bar/@quux), though I can't see any way to exploit it beyond potentially hiding URL contents in logs. Was going to file, but figured I should pop in here first to see if I'm missing something.

Hey there! I'm making a database with nano currently

The current approach I'm taking with making user accounts is to create a new document in the users database

I have two special fields called "username" and "password"

How can I make it so that the password isn't stored as plain text?

Don't think it's safe that admins can view passwords right out in the open there lol

is there a way to find and modify a document? Like this mongo equivalent http://stackoverflow.com/questions/6997835/how-does-mongodb-deal-with-concurent-updates ???

@streunerlein

@vicmania2007 I do not quite understand your question - "find" works by Views, "modify" by regular HTTP request. "Concurrency" has been built into CouchDB 2.0 when used in a clustered environment.

(ok, last sentence is confusing: "Concurrency" is generally solved by CouchDBs Conflict Management, there is no locking, but there is a "relaxed" handling of conflicts)

@JelaniThompson CouchDB salts and hashes user passwords, so you enter them in plaintext but they will not get stored in plaintext (but hashed).

@vicmania2007

@streunerlein my question was how you will find a document and update it. looks like we have to use find method to find the document and update it using db

Db.insert

Nevermind I got the solution.

Thanks @streunerlein

Dominique Sandoz

@streunerlein

@vicmania2007 Yeah, because of CouchDBs architecture, you cannot really "find" documents like you would in other DBs. You find it by filtering a View that contains the document.

Alright, good luck
