Convert issue form responses to JSON
This package can be used to parse GitHub issues into machine-readable JSON for processing. In particular, it is designed to work with issue forms to perform basic transformations on the issue body, resulting in a consistent JSON output.
Issues submitted using issue forms use a structured Markdown format. So long as the issue body is not heavily modified by the user, we can reliably parse the issue body into a JSON object.
npm i @github/issue-parserHere is a simple example of how to use this package in your project.
import{parseIssue}from'@github/issue-parser'constissue=parseIssue('<issue body>','<template>')Assuming the issue and template look like these examples:
The resulting issue object will look like the following:
{name: 'this-thing',nickname: 'thing',color: ['blue'],shape: ['square'],sounds: ['re','mi'],topics: [],description: 'This is a description.\n\nIt has multiple lines!',notes: '- Note\n- Another note\n- Lots of notes',code: 'const thing = new Thing()\nthing.doThing()','code-string': 'thing.toString()','is-thing': {selected: ['Yes'],unselected: ['No']},'is-thing-useful': {selected: ['Sometimes'],unselected: ['Yes','No']},'read-team': 'IssueOps-Demo-Readers','write-team': 'IssueOps-Demo-Writers'}This is the main function of the package. It takes two arguments:
issue: string- The body of the issue to be parsedtemplate: string- (Optional) The issue form template used to create the issueoptions?: { slugify?: boolean }- (Optional) Additional parsing options to use when processing the issue body
If the template value is provided, the package will attempt to transform the
issue response values into different types based on the type property of the
specific field in the template. If the template value is omitted, all parsed
values will be returned as strings. For information on the transformations that
are applied, see the Transformations section.
slugify: boolean- If set totrue, any parsed keys that are not found in the issue forms template (if provided) will be converted to slugs using the slugify package. Otherwise, the original header value will be used as the object key.
Parses an issue form template and returns an object. This can be used to match form responses in the issue body with the fields, so that you can perform additional validation.
When parsing an issue and the associated form template, this package will attempt to match field IDs with response values. If a match is found, the field ID will be used in the parsed object keys (instead of the header value from the markdown response). If no match is found, the header text is used as the object key.
For example, if you have the following issue form template:
name: Example Requestdescription: Submit an example requesttitle: '[Request] Example'body:
- type: inputid: nameattributes:
label: The Name of the Thingdescription: The name of the thing you want to create.placeholder: this-is-the-thingvalidations:
required: trueAnd the following issue body:
### The Name of the Thing
this-thing
### The Nickname of the Thing
thingThe resulting parsed issue would be:
The following transformations will take place for responses, depending on the input type. The type is inferred from the issue form template. For information on each specific type, see Syntax for GitHub's form schema.
Before:
This is a response
After (no change):
This is a response
Note
Empty lines are preserved in multiline responses.
Before:
First line :D
Third line!
After:
First line :D\n\nThird line!
Before:
red, blue, green
After:
["red", "blue", "green"]Before:
- [x] Pick me!
- [ ] Don't pick me D:
After:
{
"selected": ["Pick me!"],
"unselected": ["Don't pick me D:"]
}In the following situations, an input will be omitted from the output JSON:
| Scenario | Example |
|---|---|
| Invalid Heading | ## This is invalid |
| Empty Heading | ### |
This is a value | |
| No Value | ### This is a heading |
### This is another | |
This is a value |
Normally, if a form is submitted with empty field(s), they will be included in the issue body as one of the following, depending on the input type in the form template.
| Type | No Response |
|---|---|
dropdown | None |
input | _No response_ |
textarea | _No response_ |
### Dropdown Field
None
### Input or Textarea Field_No response_### Checkboxes Field-[ ] Item A
-[ ] Item BThese will be converted to one of the following, based on the type of input specified in the issue form template:
| Type | Output |
|---|---|
checkboxes | { "selected": [], "unselected": []} |
dropdown | [] |
input | undefined |
textarea | undefined |
{ // Uses the ID value from the issue form template as the key"name": "this-thing", // Uses the original header value from the issue body"The Nickname of the Thing": "thing" }
