Run this to install Nesu as a global package:
$ npm install -g @rappopo/nesu
Go to your project folder, and invoke:
$ nesu
The first time Nesu starts, it’ll create an empty config.json
configuration file, transformer
and last_seq
folder in your project folder. Quit Nesu by pressing Ctrl-c
and start customizing its configurations (please see details below).
Go to your node.js application project folder, and type:
$ npm install --save @rappopo/nesu
Create an empty new js file, e.g.: nesu.js, and enter the following code:
var nesu = require('@rappopo/nesu')nesu()
Also create the config.json
configuration file in the same folder as nesu.js file above like this example below:
{"db": {"mydb1": {"idleTimeout": 0},"mydb2": {"cdb": {"url": "http://couchdb:5984","name": "mycouchdb1"},"es": {"url": "http://elasticsearch:9200","name": "myesindex1"},"bulkLimit": 500,"idleTimeout": 10}},"default": {"bulkLimit": 5000}}
And finaly:
$ node nesu.js
But most likely you’ll want to use a process manager like pm2.
Program will automatically create an empty config.js
file if missing. Two empty folders transformer
and last_seq
will also be created.
You might also want to change the configuration object above dynamically within your script, like this:
...nesu({ config: <config> })...
The value of <config>
will simply be merged with the above configuration file.
