NodeJS "Single Executable Applications"[^1] are standalone CLI tools that embed
|
||||
bundled scripts in a special standalone copy of the NodeJS binary.
|
||||
|
||||
[SheetJS](https://sheetjs.com) is a JavaScript library for reading and writing
|
||||
data from spreadsheets.
|
||||
|
||||
This demo uses NodeJS SEA and SheetJS to create a standalone CLI tool for
|
||||
parsing spreadsheets and generating CSV rows.
|
||||
|
||||
:::info pass
|
||||
|
||||
It is strongly recommended to install NodeJS on systems using SheetJS libraries
|
||||
in command-line tools. This workaround should only be considered if a standalone
|
||||
binary is considered desirable.
|
||||
|
||||
:::
|
||||
|
||||
:::caution NodeJS SEA support is considered experimental.
|
||||
|
||||
Great open source software grows with user tests and reports. Any issues should
|
||||
be reported to the NodeJS single-executable project for further diagnosis.
|
||||
|
||||
:::
|
||||
|
||||
## Integration Details
|
||||
|
||||
The [SheetJS NodeJS module](/docs/getting-started/installation/nodejs) can be
|
||||
required from NodeJS SEA base scripts.
|
||||
|
||||
:::info pass
|
||||
|
||||
**NodeJS SEA does not support ECMAScript Modules!**
|
||||
|
||||
A CommonJS script is conveniently included in the SheetJS NodeJS module package.
|
||||
|
||||
:::
|
||||
|
||||
At a high level, single-executable applications are constructed in four steps:
|
||||
|
||||
1) Pre-process an existing NodeJS script, creating a SEA bundle.
|
||||
|
||||
2) Copy the NodeJS binary and remove any signatures.
|
||||
|
||||
3) Inject the SEA bundle into the unsigned NodeJS binary.
|
||||
|
||||
4) Re-sign the binary.
|
||||
|
||||
:::note pass
|
||||
|
||||
macOS and Windows enforce digital signatures. Both operating systems will warn
|
||||
users if a signed program is modified.
|
||||
|
||||
Existing signatures should be removed *before* injecting the SEA bundle. After
|
||||
injecting the SEA bundle, the binary should be resigned.
|
||||
|
||||
:::
|
||||
|
||||
### Script Requirements
|
||||
|
||||
Scripts that exclusively use SheetJS libraries and NodeJS built-in modules can
|
||||
be bundled using NodeJS SEA. Due to limitations in the SEA bundler, a special
|
||||
`require` function must be created manually:
|
||||
|
||||
```js
|
||||
const { createRequire } = require('node:module');
|
||||
require = createRequire(__filename);
|
||||
const { readFile, utils } = require("xlsx");
|
||||
```
|
||||
|
||||
For example, the following script accepts one command line argument, parses the
|
||||
specified file using the SheetJS `readFile` method[^2], generates CSV text from
|
||||
the first worksheet using `sheet_to_csv`[^3], and prints to terminal:
|
||||
|
||||
```js title="sheet2csv.js"
|
||||
// For NodeJS SEA, the CommonJS `require` must be used
|
||||
const { createRequire } = require('node:module');
|
||||
require = createRequire(__filename);
|
||||
const { readFile, utils } = require("xlsx");
|
||||
|
||||
// argv[2] is the first argument to the script
|
||||
const filename = process.argv[2];
|
||||
|
||||
// read file
|
||||
const wb = readFile(filename);
|
||||
|
||||
// generate CSV of first sheet
|
||||
const ws = wb.Sheets[wb.SheetNames[0]];
|
||||
const csv = utils.sheet_to_csv(ws);
|
||||
|
||||
// print to terminal
|
||||
console.log(csv);
|
||||
```
|
||||
|
||||
### SEA Bundles
|
||||
|
||||
SEA Bundles are blobs that represent the script and supporting libraries.
|
||||
|
||||
#### Configuration
|
||||
|
||||
SEA configuration is specified using a special JSON file. Assuming no special
|
||||
assets are bundled with the script, there are two relevant fields:
|
||||
|
||||
- `main` is a relative path to the entry script.
|
||||
- `output` is a relative path to the output file (typically ending in `.blob`)
|
||||
|
||||
For example, the following configuration specifies `sheet2csv.js` as the entry
|
||||
script and `sheet2csv.blob` as the output blob:
|
||||
|
||||
```js title="sheet2csv.json"
|
||||
{
|
||||
"main": "sheet2csv.js",
|
||||
"output": "sheet2csv.blob"
|
||||
}
|
||||
```
|
||||
|
||||
#### Construction
|
||||
|
||||
The main `node` program, with the command-line flag `--experimental-sea-config`,
|
||||
will generate a SEA bundle:
|
||||
|
||||
```bash
|
||||
node --experimental-sea-config sheet2csv.json
|
||||
```
|
||||
|
||||
The bundle will be written to the file specified in the `output` field of the
|
||||
SEA configuration file.
|
||||
|
||||
#### Injection
|
||||
|
||||
A special `postject` utility is used to add the SEA bundle to the NodeJS binary.
|
||||
The specific command depends on the operating system.
|
||||
|
||||
On macOS, assuming the copy of the NodeJS binary is named `sheet2csv` and the
|
||||
SEA bundle is named `sheet2csv.blob`, the following command injects the bundle:
|
||||
|
||||
```bash
|
||||
npx -y postject --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 --macho-segment-name NODE_SEA sheet2csv NODE_SEA_BLOB sheet2csv.blob
|
||||
```

||||

||||

|
||||
```bash
|
||||
mkdir sheetjs-sea
|
||||
cd sheetjs-sea
|
||||
npm init -y
|
||||
```
|
||||
|
||||
2) Save the [contents of the `sheet2csv.js` code block](#script-requirements)
|
||||
to `sheet2csv.js` in the project folder.
|
||||
|
||||
3) Install the SheetJS dependency:

### Script Test
|
||||
|
||||
:::caution pass
|
||||
|
||||
Before building the standalone app, the base script should be tested using the
|
||||
local NodeJS platform.
|
||||
|
||||
:::
|
||||
|
||||
4) Download the test file <https://sheetjs.com/pres.numbers>:
|
||||
|
||||
```bash
|
||||
curl -LO https://sheetjs.com/pres.numbers
|
||||
```
|
||||
|
||||
5) Run the script and pass `pres.numbers` as the first argument:
|
||||
|
||||
```bash
|
||||
node sheet2csv.js pres.numbers
|
||||
```
|
||||
|
||||
The script should display CSV contents from the first sheet:
|
||||
|
||||
```
|
||||

|
||||
Bill Clinton,42
|
||||
GeorgeW Bush,43
|
||||
Barack Obama,44
|
||||
Donald Trump,45
|
||||
Joseph Biden,46
|
||||
```
|
||||
|
||||
### SEA Bundle
|
||||
|
||||
6) Save the [contents of the `sheet2csv.json` code block](#configuration) to
|
||||
`sheet2csv.json` in the project folder.
|
||||
|
||||
7) Generate the SEA bundle:
|
||||
|
||||
```bash
|
||||
node --experimental-sea-config sheet2csv.json
|
||||
```
|
||||
|
||||
### SEA Injection
|
||||
|
||||
8) Create a local copy of the NodeJS binary. On macOS and Linux:
|
||||
|
||||
```bash
|
||||
cp `which node` sheet2csv
|
||||
```
|
||||
|
||||
<Tabs groupId="triple">
|
||||
<TabItem value="darwin-x64" label="MacOS">
|
||||
|
||||
9) Remove the code signature.
|
||||
|
||||
```bash
|
||||
codesign --remove-signature ./sheet2csv
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
<TabItem value="linux-x64" label="Linux">

|
||||
|
||||
10) Inject the SEA bundle.
|
||||
|
||||
<Tabs groupId="triple">

|
||||
```
|
||||
|
||||
11) Resign the binary. The following command performs macOS ad-hoc signing:
|
||||
|
||||
```bash
|
||||
codesign -s - ./sheet2csv
|
||||
```
|
||||
|
||||
</TabItem>
|
||||
<TabItem value="linux-x64" label="Linux">
|
||||
|
||||
```bash
|
||||
npx -y postject --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 sheet2csv NODE_SEA_BLOB sheet2csv.blob
|
||||
```
|
||||
|
||||
11) Observe that many Linux distributions do not enforce code signatures.
|
||||

</TabItem>
|
||||
</Tabs>
|
||||
|
||||
|
||||
### Standalone Test
|
||||
|
||||
12) Run the command and pass `pres.numbers` as the first argument:
|
||||
|
||||
```bash
|
||||
./sheet2csv pres.numbers
|
||||
```
|
||||
|
||||
The program should display the same CSV contents as the script (from step 5)
|
||||
|
||||
<Tabs groupId="triple">
|
||||
<TabItem value="darwin-x64" label="MacOS">
|
||||
|
||||
13) Validate the binary signature. On macOS:
|
||||
|
||||

[Deno](https://docs.deno.com/runtime/manual/tools/compiler) is a JavaScript
|
||||
runtime with support for compiling scripts into self-contained executables.
|
||||
|
||||
[SheetJS](https://sheetjs.com) is a JavaScript library for reading and writing
|
||||
data from spreadsheets.
|
||||
|
||||
This demo uses the Deno compiler and SheetJS to create a standalone CLI tool for
|
||||
parsing spreadsheets and generating CSV rows.
|
||||
|
||||
:::info pass
|
||||
|
||||
It is strongly recommended to install Deno on systems using SheetJS libraries in
|
||||
command-line tools. This workaround should only be considered if a standalone
|
||||
binary is considered desirable.
|
||||
|
||||
:::
|
||||
|
||||
:::caution Deno support is considered experimental.
|
||||
|
||||
Great open source software grows with user tests and reports. Any issues should
|
||||
be reported to the Deno project for further diagnosis.
|
||||
|
||||
:::
|
||||
|
||||
## Integration Details
|
||||
|
||||
The [SheetJS Deno module](/docs/getting-started/installation/deno) can be
|
||||
imported from Deno scripts.
|
||||
|
||||
`deno compile` generates a standalone executable that includes the entire JS
|
||||
runtime as well as user JS code.
|
||||
|
||||
### Script Requirements
|
||||
|
||||
Scripts that exclusively use SheetJS libraries and Deno built-in modules can be
|
||||
bundled using `deno compile`. The ESM script should be imported directly:
|
||||
|
||||
<CodeBlock language="ts">{`\
|
||||
// @deno-types="https://cdn.sheetjs.com/xlsx-${current}/package/types/index.d.ts"
|
||||
import * as XLSX from 'https://cdn.sheetjs.com/xlsx-${current}/package/xlsx.mjs';`}
|
||||
</CodeBlock>
|
||||
|
||||
For example, the following script accepts one command line argument, parses the
|
||||
specified file using the SheetJS `readFile` method[^1], generates CSV text from
|
||||
the first worksheet using `sheet_to_csv`[^2], and prints to terminal:
|
||||
|
||||
<CodeBlock language="ts" title="sheet2csv.ts">{`\
|
||||
// @deno-types="https://cdn.sheetjs.com/xlsx-${current}/package/types/index.d.ts"
|
||||
import * as XLSX from 'https://cdn.sheetjs.com/xlsx-${current}/package/xlsx.mjs';
|
||||
import * as cptable from 'https://cdn.sheetjs.com/xlsx-${current}/package/dist/cpexcel.full.mjs';
|
||||
XLSX.set_cptable(cptable);
|
||||
\n\
|
||||
/* Deno.args[0] is the first argument to the script */
|
||||
const filename = Deno.args[0];
|
||||
\n\
|
||||
/* read file */
|
||||
const wb = XLSX.readFile(filename);
|
||||
\n\
|
||||
/* generate CSV of first sheet */
|
||||
const ws = wb.Sheets[wb.SheetNames[0]];
|
||||
const csv = utils.sheet_to_csv(ws);
|
||||
\n\
|
||||
/* print to terminal */
|
||||
console.log(csv);`}
|
||||
</CodeBlock>
|
||||
|
||||
### Deno Permissions
|
||||
|
||||
The same permissions that apply to normal Deno scripts apply to the compiler:
|
||||
|
||||
- The `--allow-read` option must be specified to allow the program to read files
|
||||
from the filesystem with the SheetJS `readFile` [^3] method.
|
||||
|
||||
- The `--allow-write` option must be specified to allow the program to write
|
||||
files to the filesystem with the SheetJS `writeFile` [^4] method.
|
||||
|
||||
- The `--allow-net` option must be specified to allow the program to download
|
||||
and upload spreadsheets.
|
||||
|
||||
More flags can be found in the official permissions list[^5]

## How JSON and APIs Understand Time
|
||||
|
||||
JSON does not have a native representation for JavaScript Date objects.
|
||||
|
||||
Starting from a Date object, the `JSON.stringify` method will encode the object
|
||||
as a ISO 8601 date string. Applying `JSON.parse` to the result will return the
|
||||
string rather than a proper Date object.
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
ws(("new Date#40;#41;"\nObject))
|
||||
jstr[["'#quot;2001-01-01T00:00:00.000Z#quot;'"\nEncoded String]]
|
||||
js[["#quot;2001-01-01T00:00:00.000Z#quot;"\nJavaScript String]]
|
||||
ws --> |JSON\nstringify| jstr
|
||||
jstr --> |JSON.parse\n\n| js
|
||||
js --> |\nJSON.stringify| jstr
|
||||
```
|
||||
|
||||
SheetJS utility functions will not try to interpret those strings as dates.
|
||||
Instead, the strings will be translated to text.
|
||||
|
||||
In the following example, the "ISO Text" data will be converted to a string cell
|
||||
while the "Date Obj" data will be converted to a spreadsheet date.
|
||||
|
||||
```jsx live
|
||||
function SheetJSONDates() { return ( <button onClick={() => {
|
||||
const aoa = [
|
||||
["ISO Text", "2001-01-01T00:00:00.000Z"], // B1 will be text
|
||||
["Date Obj", new Date("2001-01-01T00:00:00.000Z")] // B2 will be a date
|
||||
];
|
||||
const ws = XLSX.utils.aoa_to_sheet(aoa);
|
||||
const wb = XLSX.utils.book_new(ws, "Data");
|
||||
XLSX.writeFile(wb, "SheetJSONDates.xlsx");
|
||||
}}>Click to Export Sample Data</button> ); }
|
||||
```
|
||||
|
||||
:::caution pass
|
||||
|
||||
Many API wrapper libraries return dates as strings instead of Date objects.
|
||||
|
||||
If the SheetJS operations generate string cells, review the documentation for
|
||||
the wrapper library to ensure the other library is properly handling dates.

||||

### Fixing Arrays of Objects
|
||||
|
||||
Many APIs will return data as JSON objects. When particular fields are known to
|
||||
contain date strings, they can be manually fixed.
|
||||
|
||||
For example, the [Export Tutorial](/docs/getting-started/examples/export) makes
|
||||
a final array of objects with birthdays stored as strings:
|
||||
|
||||
```js
|
||||
const rows = [
|
||||
{ name: "George Washington", birthday: "1732-02-22" },
|
||||
{ name: "John Adams", birthday: "1735-10-19" },
|
||||
// ... one row per President
|
||||
];
|
||||
```
|
||||
|
||||
If this dataset is exported, the `birthday` column will contain raw text values.
|
||||
A single `Array#map` operation can create a fixed dataset:
|
||||
|
||||
```js
|
||||
const new_rows = rows.map(({birthday, ...rest}) => ({birthday: new Date(birthday), ...rest}))
|
||||
```
