Code samples

This declaration will create a MarkLogic database and a collection:

var db = marklogic.createDatabaseClient(conn);
 
// create Collection countries
var q = marklogic.queryBuilder;
db.documents.query(
    q.where(
        q.collection('countries'),
        q.value('region', 'Africa'),
        q.or(
            q.word('background', 'France'),
            q.word('Legal system', 'French')
        )
    )
).result(function(documents) {
    documents.forEach(function(document){ 
        console.log(JSON.stringify(document)); 
    });
});

This declaration will create a MarkLogic collection “fake data” and a useDeleteLink to the collection “fake data”:

db.documents.removeAll({collection: 'fake data'})
            .result()
            .then(response => console.log('Removed collection ' + response.collection))
            .catch(error => console.log(error));

This declaration will create a MarkLogic collection “fake data” and a useInsertLink to the collection “fake data”:

db.documents.write(
  data.map((item) => {
    return {
      uri: `/${item.guid}.json`,
      contentType: 'application/json',
      collections: ['fake data'],
      content: item
    }
  })
)
.result()
.then(response => console.dir(JSON.stringify(response)))
.catch(error => console.error(error));
