NBB: Ad-hoc CLJS Scripting on Node.js

Nbb

Not babashka. Node.js babashka!?

Ad-hoc CLJS scripting on Node.js.

Status

Experimental. Please report issues here.

Goals and features

Nbb's main goal is to make it easy to get started with ad hoc CLJS scripting on Node.js.

Additional goals and features are:

  • Fast startup without relying on a custom version of Node.js.
  • Small artifact (current size is around 1.2MB).
  • First class macros.
  • Support building small TUI apps using Reagent.
  • Complement babashka with libraries from the Node.js ecosystem.

Requirements

Nbb requires Node.js v12 or newer.

How does this tool work?

CLJS code is evaluated through SCI, the same interpreter that powers babashka. Because SCI works with advanced compilation, the bundle size, especially when combined with other dependencies, is smaller than what you get with self-hosted CLJS. That makes startup faster. The trade-off is that execution is less performant and that only a subset of CLJS is available (e.g. no deftype, yet).

Usage

Install from NPM:

Omit for a local install.

Try out an expression:

And then install some other NPM libraries to use in the script. E.g.:

Create a script which uses the NPM libraries:

Call the script:

Macros

Nbb has first class support for macros: you can define them right inside your file, like you are used to from JVM Clojure. Consider the macro to make working with promises more palatable:

Using this macro we can look async code more like sync code. Consider this puppeteer example:

Using this becomes:

See the puppeteer example for the full code.

Since v0.0.36, nbb includes promesa which is a library to deal with promises. The above macro is similar to .

Startup time

The baseline startup time for a script is about 170ms seconds on my laptop. When invoked via this adds another 300ms or so, so for faster startup, either use a globally installed or use to bypass .

Dependencies

NPM dependencies

Nbb does not depend on any NPM dependencies. All NPM libraries loaded by a script are resolved relative to that script. When using the Reagent module, React is resolved in the same way as any other NPM library.

Classpath

To load files from local paths or dependencies, you can use the argument. The current dir is added to the classpath automatically. So if there is a file relative to your current dir, then you can load it via . Note that uses the same naming conventions for namespaces and directories as other Clojure tools: in the namespace name becomes in the directory name.

To load dependencies from the Clojure ecosystem, you can use the Clojure CLI or babashka to download them and produce a classpath:

and then feed it to the argument:

Currently only reads from directories, not jar files, so you are encouraged to use git libs. Support for files will be added later.

Current file

The name of the file that is currently being executed is available via or on the metadata of vars:

Reagent

Nbb includes which will be lazily loaded when required. You can use this together with ink to create a TUI application:

:

Promesa

Working with callbacks and promises can become tedious. Since nbb v0.0.36 the namespace is included with the and macros. An example:

Also see API docs.

Js-interop

Since nbb v0.0.75 applied-science/js-interop is available:

Most of this library is supported in nbb, except the following:

  • destructuring using
  • property access using notation. In nbb, you must use keywords.

See the example of what is currently supported.

Examples

See the examples directory for small examples.

Also check out these projects built with nbb:

API

See API documentation.

JavaScript is a versatile platform that allows easy customization of client-side scripting tools. In some applications, it's useful to have some sort of spreadsheet interface that is easy to code and maintain. The SpreadJS client-side JavaScript spreadsheet component, part of the SpreadJS package, is perfect for this.

Import/Export to Excel in JavaScript

Set Up The JavaScript Spreadsheet Project

To start off we can use the SpreadJS files hosted on NPM. To do this, we can install using command line argument. Open up a command prompt and navigate to the location of your application. There, you can install the required files with one command.

In this case, we need the base Spread-Sheets library, Spread-ExcelIO, and jQuery:

npm i @grapecity/spread-sheets @grapecity/spread-excelio jquery

Once those are installed, we can add references to those script and css files in our code:

Then add a script to the page that initializes the Spread.Sheets component, and a div element to contain it (since the SpreadJS spreadsheet component utilizes a canvas, this is necessary to initialize the component):

Add Excel Import Code

We need to create an instance of the client-side ExcelIO component that we can use to actually open the file:

Then we need to add a function to import a file. In this example, we import a local file, but you can do the same thing with a file on a server. If you’re importing a file from a server, you need to reference the location. The following is an example of an input element where the user can enter the location of the file:

Once you have that, you can directly access that value in script code:

The following code for the import function just uses a local file for the "excelUrl" variable:

Regardless of whether you're referencing a file on a server or locally, you'll need to add the following to your script inside the $(document).ready function:

Adding Data To The Imported Excel File

In this tutorial, we import a local file that uses the “Profit loss statement” Excel template.

The Excel Template

Now we can use Spread.Sheets script to add another revenue line into this file. Let’s add a button to the page that will do just that:

We can write a function for the click event handler for that button to add a row and copy the style from the previous row in preparation for adding some data. To copy the style, we will need to use the copyTo function and pass in:

  • the origin and destination row and column indices
  • row and column count
  • the CopyToOptions value for style

All of the following script code for adding data and a Sparkline will be contained within this button click event handler. For most of the data, we can use the setValue function. This allows us to set a value in a sheet in Spread by passing in a row index, column index, and value:

Set a SUM formula in column P to match the other rows and set a percentage for column Q:

Lastly, we can copy the formulas from the previous rows to the new row for columns R through AD using the copyTo function again, this time using CopyToOptions.formula:

Adding A Sparkline

Now we can add a sparkline to match the other rows of data. To do this, we need to provide a range of cells to get the data from and some settings for the sparkline. In this case, we can specify:

  • the range of cells we just added data to
  • settings to make the sparkline look like the other sparklines in the same column

After that, we call the setSparkline method and specify:

  • a location for the sparkline
  • the location of the data
  • the orientation of the sparkline
  • the type of sparkline
  • the settings we created

If you were to try running the code now, it might seem a little slow because the workbook is repainting every time data is changed and styles are added. To drastically speed it up and increase performance, Spread.Sheets provides the ability to suspend painting and the calculation service. Let’s add the code to suspend both before adding a row and its data, and then resume both after:

Once we add that code, we can open the page in a web browser and see the Excel file load into Spread.Sheets with an added revenue row. Important: Keep in mind that Chrome doesn’t allow you to open local files for security purposes, so you need to use a web browser like Firefox to successfully run this code. Alternatively, if you load a file from a website URL, it should open fine in any browser.

The Excel Template

The page with a button for adding a revenue row

Adding Excel Export Code

Finally, we can add a button to export the file with the added row. To do this, we can use the client-side ExcelIO code built into Spread.Sheets:

That code gets the export file name from an exportFileName input element. We can define it and let users name the file like so:

Then we can add a button that calls this function:

The finished page after importing and editing an Excel file.

Once you add a revenue row, you can export the file using the Export File button. Make sure to add the FileSaver external library to allow users to save the file where they want:

When the file is successfully exported, you can open it in Excel and see that the file looks like it did when it was imported, except there is now an extra revenue line that we added.

The exported file loaded into Excel

This is just one example of how you can use SpreadJS JavaScript spreadsheets to add data to your Excel files and then export them back to Excel with simple JavaScript code.

Node is an open source server platform that runs on top of Google Chrome’s JavaScript engine called V8. Node includes basically everything needed to execute a program written in JavaScript. Ryan Dahl developed it in 2009. My blog post Why JavaScript is a pretty good overview of why I like and use JavaScript for many things.

Excel is a really commonly used spreadsheet program that lots of companies use to transmit data. While working at multiple market research companies, I’ve used it lots of times for final client deliverables. Excel has gotten very powerful over the last ten years and now includes a lot of machine learning like functionality.

Over the years, I’ve probably used dozens of Excel file creators and parsers. In pretty much every application or web service there becomes a need to output a file to Excel or csv. Finding a really good library that doesn’t require Excel to exist on the server can be really hard.

ExcelJS is a pretty good package for reading and manipulating Excel files. Prior to using ExcelJS I had spent a lot of time trying to get excel4node to work and it just never really things that I needed or wanted.

ExcelJS provides a pretty simple interface to generate pretty advanced Excel documents that can include things like formatting, borders, formulas, pivot tables and even some graphs. The big thing I like about ExcelJS is that I can update existing files and use them like a template, and it actually works with pivot tables. A lot of the open source Excel writers don’t work with pivot tables.

Let’s pretend we were working for the accounting department and needed to work on a way to report on the number of people that owe money. We cobble together some sort of query and get our data to look something like this:

Ok, it’s pretty simple sample data but it’s good enough to provide how easy it is to create a simple Excel based report. Let’s begin by getting the packages we need.

Getting Started – Installation

From the root of your project you can simply open a new terminal window and run “npm install exceljs”. After the installation is complete, we should see that our package.json file is updated. (If you don’t have a package.json file you can create one by running “npm init”)

It should include changes like:

In index.js or whatever file you’re using, it’s pretty easy to declare and begin using the file. You’ll need to include it at the top of the file like so

A workbook is an Excel file that contains many worksheets. You need to declare a new Workbook so that you have something to work in.

Note: I like to use Standard Style, so I don’t generally use semicolons and I let Prettier worry about silly things like tabs vs spaces. 🙂

Everything in Excel works off of the concept of a worksheet. A worksheet is a single page in the file. A really simple way of thinking of them is to think about the tabs at the bottom.

A second parameter can be optionally provided when creating the worksheet that can specify things like the tab colour to use, whether to show gridlines or other things.

Let’s say we wanted to create an Excel file that looked like the following, the code to do this isn’t really all that complex.

Excel works off of concepts called rows and cells. A row would be 1,2, 3,4, 5, etc. Anything horizontal is a row.

Looking vertically (or up and down) is a column. For example, “B” is a row.

A cell is a particular spot, it’s address is made up of a column and then a row number. For example “A1” is the first cell in a spreadsheet.

Worksheet Columns

ExcelJS has created a pretty helpful concept called columns off of the worksheet object. By using it we can easily dump an array into Excel without really having to do much manipulation.

Formatting the Header

The header in our example doesn’t really have too much formatting other than being bold and about as wide as the titles. Doing this is with a loop and taking advantage of the row functionality is pretty easy.

Inserting The Data Into Excel

To do this, I’m doing a for each on the data array and immediately putting the values into Excel.

One thing I can’t emphasize enough is that in Excel everything is 1 based, meaning that you must start with 1 instead of 0 when looping through arrays.

I’ve seen a lot of Excel newbies that spend a lot of time trying to debug why their sheet isn’t working because they forgot Excel is 1 based instead of 0 based.

You can see that I’m using destructuring (“…”) to put all of the existing values in and then I’m adding some custom formulas for each row.

Formatting Data

Formatting data is one of the most important parts of setting up an Excel sheet so that your users can easily grasp what they’re looking at and make wise decisions off of it. Formatting data means we’re adding the $, a percentage sign or maybe we’re switching it accounting style which

Data can be formatted at the column, row or cell levels. I generally try to keep formatting at the column level which means I try to keep the same data type in every column.

Columns need to use a number, which is also 1 based. To do this we basically convert the letter to a a number by its index in the English alphabet. So column A is 1, column B is 2, and so on.

Formatting Borders

Formatting cells in Excel with borders is a great way of drawing attention to things. Lots of companies have been using this for a long time, ie: newspapers, magazines, and web pages.

I like to start every project with outlining the rows, and table outline. ExcelJS has a number of border properties that it supports. The styles it supports are as follows:

  • thin
  • dotted
  • dashDot
  • hair
  • dashDotDot
  • slantDashDot
  • mediumDashed
  • mediumDashDotDot
  • mediumDashDot
  • medium
  • double
  • thick

I generally only use “thin” or “none”. Thin is the standard border that you normally see in Excel.

In the example, we set the top, bottom, left, and right border styles for each cell individually. I haven’t found a way to do this with a range and haven’t had a big enough file to need to do this more efficiently.

Saving the Excel File

Saving the Excel file is pretty easy , it just requires specifying a file name and a file path if needed.

Wrapping Things Up

I’ve created a git repo with all of the code for creating an Excel File with NodeJS and quite a few comments. You can see the repo on github: https://github.com/brcline/getting-started-with-exceljs

ExcelJS has some really great documentation and a really active community of supporters. For the most part, the API is very similar to the way things were done in VB6 / VBA so you should be able to steal ideas and examples from the past and be able to do some pretty sophisticated things.

How to open and save an Excel file to server in the Spreadsheet

Description

This Knowledge Base explains the way to save the Spreadsheet data as Excel file to server and load the Excel into the Spreadsheet.

Solution

You can use “openFromJson” and “saveAsJson” client side methods to achieve this requirement. If you save the spreadsheet as an Excel file to server, you need to send the file name, json data, content type, version type from client to server. If you open the Excel in spreadsheet, you need to send file name from client to server.
