ember-cli-deploy is an index-adapter for Couchbase. This ember-cli addon lets you deploy your ember-cli app's index.html to a couchbase server.
First you must configure the addon using config/deploy.json. Here's
a sample config (note its missing configuration for an asset-adapter).
module.exports = {
development: {
buildEnv: 'development',
store: {
type: 'couchbase',
host: 'couchbase://development.couchbase.server.local',
bucketName: '<mybucketname>'
},
},
production: {
store: {
type: 'couchbase',
host: 'couchbase://production.couchbase.server.com',
bucketName: '<mybucketname>'
},
}
}
When you do ember deploy:index -e production, it will
- Upload the contents of the index.html to the key
<project-name>:<sha>as a doc{ content: "<html>...." }. - Then it will update the manifest with details of the freshly deployed index.html without activating it.
The aforementioned manifest is a doc stored in couchbase keyed by
<project-name>:index.html:manifest. It is of the form
{
current: "<project-name>:<sha>",
revisions: ["<project-name>:<sha>", "<project-name>:<sha>", "<project-name>:<sha>"]
}Currently you can override the manifest's revisions size, but it
defaults to 10. What that means is that it keeps track of the last
10 deploys.
Here's a simple ExpressJS + Couchbase Node.js SDK example. Note it
uses GET parameter index_key to reference which <sha> version of
index.html to display.
var express = require("express"),
couchbase = require("couchbase"),
cbConfig = { host: 'couchbase://127.0.0.1', bucketName: 'default' },
cbClient = new couchbase.Cluster(cbConfig.host),
cbBucket = cbClient.openBucket(cbConfig.bucketName, cbConfig.password, function(err) {
if (err) {
console.log("Error connecting to bucket!");
} else {
console.log("Connected to bucket!");
}
});
var app = express();
app.get("/", function(req, res) {
// Send back index.html
var projectName = "my-express-project";
var indexKey = req.query.index_key;
var manifestKey = projectName + ":index.html:manifest";
cbBucket.get(manifestKey, function(err, manifestDoc) {
if (err) {
console.log(manifestKey + " not found!");
res.status(200).send("BRB");
} else {
var indexDocKey = null;
if (indexKey) {
indexDocKey = projectName + ":" + indexKey;
} else {
indexDocKey = manifestDoc.value.current;
}
console.log("Serving version `" + indexDocKey + "`");
cbBucket.get(indexDocKey, function(err, indexDoc) {
if (err) {
console.log(indexDocKey + " not found!");
res.status(200).send("Check yo self, before you wreck yoself!");
} else {
res.status(200).send(indexDoc.value.content);
}
});
}
});
});
app.listen(3000);
This has been tested with Node.js v0.10.25, Couchbase v3.0.1, ExpressJS v4.12.3
