General CLI interaction

Set up an empty project

If you don't want to maintain your user flows in the same repository the following steps describe how to setup a new project. You can skip this steps and go directly to the setup below.

  1. Create a new folder e.g. user-flow-demo for the user flows and initialize npm: npm init

run

npm version

to check it.
You should see 'user-flow-demo': '1.0.0', as first line.

Make sure you have the CLI installed:

npm i @push-based/user-flow --save-dev

now you can run it directly with user-flow. Test it:

npx user-flow --version

Prompts and interaction

We provide general interaction through the keyboard or stdin directly for testing and other crazy hacks.

Multiselect choices

These key combinations can be used on multiple choice prompts.For more details see enquirer - multiselect

command description
space Toggle the currently selected choice when options.multiple is true.
number Move the pointer to the choice at the given index. Also toggles the selected choice when options.multiple is true.
a Toggle all choices to be enabled or disabled.
i Invert the current selection of choices.
g Toggle the current choice group.

Multiple choices in the CLI

To assign multiple choices to a multiselect CLI param you have to use the param multiple times.

e.g. to select multiple formats for the collect output write:

@npx @push-based/user-flow collect -f=md -f=json

Negation

any boolean parameter of the CLI can be negated by adding --no- in front of the parameter name. A good example is the dryRun parameter. You can negate it as follow: --no-dryRun.

Report Formats and Viewer

You can either export the report as HTML or JSON format. The html file can be opened in any browser.

Use the .user-flowrc.json property persist.format and give an array as value. e.g. ['html'] or ['html', 'json'].

You can also use the CLI option --format to choose a format.

  • single format: @push-based/user-flow collect --format html
  • multiple formats: @push-based/user-flow collect --format html --format json

🤓 DX Tip:
For a faster development process you can use the --openReport or -e option to automatically open the report in the browser. The CLI will serve either the HTML report or opens the lighthouse report viewer if only a JSON format is available and displays it there. e.g. @push-based/user-flow collect --openReport

The json file can be drag & dropped into the lighthouse viewer. This format is very good for programmatic processing and foundation for most of the features of this lib. Lighthouse Viewer - File drop area

Debugging

@push-based/user-flow ships with small helpers for logging and debugging.

logVerbose

A function that logs the passed string only if the CIL options --verbose or -vis true.

Usage

./order-coffee.uf.mts

import { logVerbose } from "@push-based/user-flow";
// ...

logVerbose('test');

npx user-flow collect logs nothing
npx user-flow collect --verbose logs "test"
