Some times you want to send more then one postcard/letter/check at a time. Now you can.
- Installation
- Setup
- Basic Example
- Sending mail
- Creating addresses and bank accounts
- Handling responses
- Handling errors
- Testing
Install this the usual npm way. You need to have the node Lob library installed separately.
npm install lob-a-bunch --save
lob-a-bunch will modify an existing Lob object to give it the batching functionality.
const lobABunch = require('lob-a-bunch');
const Lob = require('lob')('YOUR API KEY');
lobABunch(Lob);To lessen the chance of conflicts or incompatibilities with the lob library use safe mode.
When using the batch functionality use batch instead of create with same payload.
lobABunch.safe(Lob);
Lob.addresses.batch([ ... ]) // instead of Lob.addresses.create
.then(() => {});
Now we're all set to use an array of recipients instead of just one.
Lob.postcards.create({
description: 'Demo Postcard job',
to: [ {
name: 'Harry Potter',
address_line1: '4 Privet Drive',
address_city: ', Elkridge',
address_state: 'MD',
address_zip: '21075',
overrides: {
data: { name: 'Harry' }
}
}, {
name: 'Ron Weasley',
address_line1: '123 Main Street',
address_city: 'Mountain View',
address_state: 'CA',
address_zip: '94041',
overrides: {
data: { name: 'Ron' }
}
} ],
front: '<html style="padding: 1in; font-size: 50;">Front HTML for {{name}}</html>',
back: '<html style="padding: 1in; font-size: 20;">Back HTML for {{name}}</html>',
data: { name: 'my favorite person' }
}).then((results) => {
console.log(results);
}).catch((err) => {
console.log(err);
});This should give use something like this back.

If a single object is passed in payload.to for sending mail or in creating an address or bank account the normal response is given. If an array is given in its place the response is as follows.
Response objects contain the listed values when given in the Promise or callback. The order of the responses is not guaranteed.
err.rejected_count- The number of requests that failed for any reason except rate limiting.err.accepted_count- The number of requests that succeeded.err.batch_count- The number of times the rate limit was hit and waited on.err.errors- An array of all the errors that came back. The errors are passed directly from lob with the added value of_requestwhich has the object sent to the API. This key only exists if there is one or more errors.err.data- An array of all the successful responses. These are purely passed through from lob.
The batch create functions will throw back an error only if no requests are successful and there is at least one error. The error has a results key which is identical to the response outline above.
Lob.postcards.create(...)
.catch((err) => {
console.log(err.results); // outputs { rejected_count: 3, ... }
});
