Who the hell are you?

+ + + +
+
+

What the hell is this?

+ +
+
+ +
+
+ + +
+
+

In the beginning.

+

+ There was SQL. +

+

+ And it was okay. +

+
+
+

And then...

+

There was noSQL!

+

And it scaled and it was all javascripty and all the hipsters loved it and everyone was happy. +

+

It's like SQL for NoSQL

+
+

Deletin' stuff

+

+
+
+
+

+ 

+> create collection nag_old_users
+> insert into nag_old_users select {username: username, email: email} from user where last_login < (new Date()).getTime()-1000*60*60*24*7
+
+

And put it over here!

+
+
+

Want to see my awesome LALR recursive descent parser?

+ +
+
+

Nope!

+ 

+handle /delete from (\S+)(?: where (.*))?/, (db, expr, cb) ->
+  query = "update #{db} set _deleted = true"
+  query += " where #{expr}" if expr
+  processExpr query, cb
+
+
+
+

There I fixed it.

+ +
+
+ +
+
+

noDB

+

So you want to add some persistence to your simple web app.

+
+
+

Okay so just require that each user have a couch installation.

+

Or make redis a dependency. Probably include some build scripts or something to make it easier since it's the only thing in the app that needs to be compiled.

+ +

Maybe it would be easier to build SQLite?

+
+
+

Nope!

+ +
+
+

noDB

+

SQL < noSQL < noDB

+
+
+

Super simple

+ 

+var users = JSON.parse(fs.readFileSync('data/users.json'))
+
+users.push({name: "newguy"});
+fs.writeFileSync('data/users.json', JSON.stringify(users));
+res.send('success');
+
+
+
+

Session storage too!

+ 

+var store = new express.session.MemoryStore;
+store.sessions = JSON.parse(fs.readFileSync('data/sessions.json'));
+
+setInterval(function(){
+  fs.writeFileSync('data/sessions.json', JSON.stringify(store.sessions));
+}, 2000);
+
+
+
+

It's basically Redis

+ It's not really +
+
+

But it is:

+
    +
  • Deployable
    • +
  • Dependency free
    • +
  • Easily backed up
    • +
  • Debuggable
    • +
+
+
+

Databases: Fixed

+ +
+
+ +
+
+

I would like to make some information available on the internet.

+
+
+

So find a shared hosting provider or something.

+

But they're kind of crappy

+
+
+

So I'll just run my own

+

On nginx or express or something!

+

But load balancing and updates and bugs and oh no.

+
+
+

Oh I know!

+ +
+
+ +
+
+
+ Augh. I wish I could just shove all this right on Akamai +
+
+
+

...

+
+
+

...

+
+

...

+
+
+

Why not?

+
+
+

Step 0: Generate static site

+

Use whatever you want. We really like Jade.

Rackspace == Akamai

+

It's cheap. 18c per GB

+

You don't have to deal directly with Akamai. Keep your soul!

+

http://www.rackspace.com/cloud/public/files/

+
+ +
+

Getting it there

+

There's a node library for that.

+

https://github.com/nodejitsu/node-cloudfiles

+
+ +
+

There's also some tooling for that.

+

https://github.com/PinionTech/cloud-loader

+
+ +
+

Relax

+

Never ever care about whether your website is up.

+

Go do something useful instead.

+
+

Yeah, it's harder to do pretty URLs.

+
+
+

So fixed

+ +
+
+
+

It's not always the right thing to just fix it

+

But sometimes it is

What the hell is this?

- -

In the beginning.

- There was SQL. -

-

-
-

And then...

-

There was noSQL!

And it scaled and it was all javascripty and all the hipsters loved it and everyone was happy. -

Why don't we take all the data...

- 

-> create collection nag_old_users
-> insert into nag_old_users select {username: username, email: email} from user where last_login < (new Date()).getTime()-1000*60*60*24*7
-
-

And put it over here!

-
-
-

Want to see my awesome LALR recursive descent parser?

- -
-
-

Nope!

- 

-handle /delete from (\S+)(?: where (.*))?/, (db, expr, cb) ->
-  query = "update #{db} set _deleted = true"
-  query += " where #{expr}" if expr
-  processExpr query, cb
-
-
-
-

There I fixed it.

- -
-
- -
-
-

noDB

-

So you want to add some persistence to your simple web app.

-
-
-

Okay so just require that each user have a couch installation.

-

Or make redis a dependency. Probably include some build scripts or something to make it easier since it's the only thing in the app that needs to be compiled.

- -

Maybe it would be easier to build SQLite?

-
-
-

Nope!

- -
-
-

noDB

-

SQL < noSQL < noDB

-
-
-

Super simple

- 

-var users = JSON.parse(fs.readFileSync('data/users.json'))
-
-users.push({name: "newguy"});
-fs.writeFileSync('data/users.json', JSON.stringify(users));
-res.send('success');
-
-
-
-

Session storage too!

- 

-var store = new express.session.MemoryStore;
-store.sessions = JSON.parse(fs.readFileSync('data/sessions.json'));
-
-setInterval(function(){
-  fs.writeFileSync('data/sessions.json', JSON.stringify(store.sessions));
-}, 2000);
-
-
-
-

It's basically Redis

- It's not really -
-
-

But it is:

-
    -
  • Deployable
    • -
  • Dependency free
    • -
  • Easily backed up
    • -
  • Debuggable
    • -
-
-
-

Databases: Fixed

- -
-
- -
-
-

I would like to make some information available on the internet.

-
-
-

So find a shared hosting provider or something.

-

But they're kind of crappy

-
-
-

So I'll just run my own

-

On nginx or express or something!

-

But load balancing and updates and bugs and oh no.

-
-
-

Oh I know!

- -
-
- -
-
-
- Augh. I wish I could just shove all this right on Akamai -
-

Step 0: Generate static site

Use whatever you want. We really like Jade.

Rackspace == Akamai

-

It's cheap. 18c per GB

-

You don't have to deal directly with Akamai. Keep your soul!

-

http://www.rackspace.com/cloud/public/files/

-
- -
-

Getting it there

-

There's a node library for that.

-

https://github.com/nodejitsu/node-cloudfiles

-
- -
-

There's also some tooling for that.

Relax

-

Never ever care about whether your website is up.

-

Go do something useful instead.

-
-

Yeah, it's harder to do pretty URLs.

So fixed

It's not always the right thing to just fix it
