### Express Setup
|
||||
|
||||
The following commands are required in order to test the [Express](https://github.com/expressjs/express) demo:
|
||||
|

```bash
|

npm install express printj xlsx express-formidable
|

node express.js

```
|

### Koa Setup

|
||||
The following commands are required in order to test the [Koa](https://github.com/koajs/koa) demo:

### Hapi Setup

**Note: Hapi demo as written only works with Hapi version 16 and below.**

|
||||
The following commands are required in order to test the [Hapi](https://github.com/hapijs/hapi) demo:

## command-line utility with micro
|
||||
|
||||
The npm module ships with the `xlsx` command line tool. For global installs, the
|
||||
script `bin/xlsx.njs` is added to a directory in `PATH`. For local installs, the
|
||||
appropriate script or symbolic link is set up in `node_modules/.bin/`.
|
||||
|
||||
The `--arrays` option directs `xlsx` to generate an array of arrays that can be
|
||||
parsed by the server. To generate files, the `json2csv` module exports the JS
|
||||
array of arrays to a CSV, the server writes the file, and the `xlsx` command is
|
||||
used to generate files of different formats.
