Quick Examples
Code 11 Example
import { SymbologyType, createStream } from 'symbology'
(async () => {
const { data } = await createStream({
symbology: SymbologyType.CODE11
}, '8765432164')
console.log('Result: ', data)
})()
This will log:
{
"data": "data:image/png+data;base64,PHN [...] eFd==",
"message": "Symbology successfully created.",
"code": 0
}
And the base64 PNG generated will look like:
MaxiCode Example
import { SymbologyType, createFile } from 'symbology'
(async () => {
const { data } = await createFile({
symbology: SymbologyType.MAXICODE,
option1: 2,
primary: '999999999840012',
fileName: 'maxiCodeExample.svg'
}, 'Secondary Message Here')
console.log('Result: ', data)
})()
This creates maxiCodeExample.svg
which looks like:
USPS Example
import { SymbologyType, createFile } from 'symbology'
(async () => {
const { data } = await createFile({
symbology: SymbologyType.ONECODE
fileName: 'uspsExample.eps'
}, '01234567094987654321-01234')
console.log('Result: ', data)
})()
This creates uspsExample.eps
which looks like:
