MARC record implementation in javascript
``
npm install marc-record-js
`
The tests contains multiple examples on how to use the module.
`
var Record = require('marc-record-js');
// Create empty record
var myRecord = new Record();// You can also make a record from string representation
var myRecord = Record.fromString(recordString);
recordString can be obtained with
function.
`
myRecord.toString()
The output of is human-readable. Example:
`
LDR leader
001 28474
100 ‡aExample Author
245 0 ‡aExample Title
500 # ‡aNote‡bSecond subfield
$3
// set record leader
myRecord.setLeader("00000cam^a22001817i^4500");// insert controlfields to the record. Proper ordering is handled automatically.
myRecord.insertControlField({
tag: "001"
value: "007045872"
});
// or using array as a parameter
myRecord.insertControlField(["001", "007045872"]});
// There is also appendControlField, which will append a controlfield to the end of the record.
// insert datafields to the record. Proper ordering is handled automatically.
myRecord.appendField({
tag: "245",
ind1: "",
ind2: "",
subfields: [
{
code: "a"
value: "The title of the book"
},
{
code: "c",
value: "Some author"
}
]
});
// or using array as a parameter
// Format is [tag,ind1,ind2,sub1code,sub1value,sub2code,sub2value,...subNcode,subNvalue]
myRecord.insertField(["245","","", "a","The title of the book'","b","Some author"]});
$3
Get array of controlfields:
myRecord.getControlfields();
Get array of datafields:
myRecord.getDatafields();
Record object has an attribute called
which contains an array of it's fields:
`
myRecord.fields
Check if record is deleted:
myRecord.isDeleted()
$3
A deep copy of the record can be made by passing the fields from a record to the constructor of new record:
var deepClonedRecord = Record.clone(myRecord);
$3
Record.isEqual(record1, record2); // true if records are deeply equal.
Alternative form for equality comparison:
record1.equalsTo(record2);
$3
Check if record contains a data field with specific value
record.containsFieldWithValue('245', 'b', 'Test field', 'c', 'Test content')
Check if record contains a control field with specific value
record.containsFieldWithValue('003', 'some value')
