Promise: a Promise that resolves with undefined.
copies( number, Optional): Specifies how many copies will be printed. While developing your application it is very useful to have a source of scales data to subscribe to, but it is inconvenient to have to actually plug in a scales device and occasionally put things on it to generate fresh data, so the PrintNode server provides a virtual scales device called PrintNode Test Scale attached to a computer id 0. 
printDialog ( boolean, Optional): displays the Print dialog for all the files indicated on this command line. silent ( boolean, Optional): Silences SumatraPDF's error messages. Supported names A2, A3, A4, A5, A6, letter, legal, tabloid, statement. paperSize ( string, Optional): Specifies the paper size. bin ( string, Optional): Select tray to print to. side ( string, Optional): Supported names duplex, duplexshort, duplexlong and simplex. monochrome ( boolean, Optional): Prints the document in black and white. scale ( string, Optional): Supported names noscale, shrink and fit. orientation ( string, Optional): Can provide 90-degree rotation of contents (NOT the rotation of paper which must be pre-set by the choice of printer defaults). subset ( string, Optional): Will print odd pages only when value is odd. The standard middleware for this is body. Then you may want to parse it as either url encoded or JSON if that's what it is. So the first thing you must do is make sure you assemble the stream of chunks into a complete piece of data. NODEJS PRINT PDF
pages ( string, Optional): Specifies which pages to print in the PDF document. So POST parameters arrive in the HTTP request body, and this is handled as a stream of data chunks by node.js. For example, type in the following line and press enter: CONSOLE > 5 '5' false > Note the difference in the outputs of the above two lines. NODEJS PRINT CODE
A global console instance configured to write to process.stdout and process.stderr. Node automatically prints the result of any line of JavaScript code without the need to instruct it to do so.
printer ( string, Optional): Send a file to the specified printer. A Console class with methods such as console.log(), console.error(), and console.warn() that can be used to write to any Node.js stream. Will throw an error if PDF not specified or not found. pdf ( string, Required): A path to the PDF file you want to print. log ) APIĪ function to print a PDF document.print(pdf) => Promise Get current directory with process.cwd() The process.cwd() method works just like the dirname variable. Use the require () Method to Print the Current Local Date-Time in NodeJS. the YYYY-MM-DD hh:mm:ss Combination Using the get Function in NodeJS. Use the getter Function to Get Specific Date Object in NodeJS. Password: "password", // corresponding passwordĭatabase: "studentsDB" // use the specified databaseĬon.Import from "pdf-to-printer" print ( "assets/pdf-sample.pdf" ). And just like that, you can get the current working directory in NodeJS. Use the new Date () Object to Create a New Date Object in NodeJS. User: "arjun", // user name to your mysql database If an uncaught exception gets thrown during the execution of your program, your program will crash. You can add multiple handlers, that can catch different kinds of errors. Host: "localhost", // ip address of server running mysql e in this example is the exception value. create a connection variable with the required details In this example, we will execute “SELECT FROM” SQL query, and we access the rows and column values using DOT operator.Įxample.js // Node.js MySQL Result Object Example We can access the records in Result Set as an array and properties of a record using DOT (.) Operator. MySQL DELETE FROM Query -Accessing properties of Result ObjectĮxample 1 – MySQL SELECT FROM Query – Accessing ResultSet. NODEJS PRINT UPDATE
MySQL UPDATE Query -Accessing properties of Result Object. MySQL INSERT INTO Query – Accessing properties of Result Object. MySQL SELECT FROM Query – Accessing ResultSet. NODEJS PRINT HOW TO
We shall see how to access properties of records in a result set and how to access properties of execution status with the help of following examples. Following table contents describe the result object for queries like select, insert, update and delete. The contents of Result Object depends on the SQL query made to MySQL Server. In this tutorial, we will go through Result objects returned by different SQL queries and how to access their properties using DOT operator.
