Gatsby-transformer-leasot NPM

gatsby-transformer-leasot

Uses leasot to parse select source files for TODO:, FIXME: and custom comments. Written in Typescript.

Example

// FIXME(Reference): improve example
// TODO: you can add a reference like this as well /Reference
// TODO: example without reference
const comeBackToImprove = () => console.log('Please improve me')

will be transformed to

{
  "todo": {
    "ref": "Reference",
    "line": 7,
    "value": "improve example",
    "file": {
      "relativePath": "README.md"
    }
  }
}

file will be a File reference, so you can query anything gatsby-source-filesystem provides

Live Example

Install

yarn add -D gatsby-transformer-leasot
# or
npm i -D gatsby-transformer-leasot

REQUIRES: gatsby-source-filesystem
You can use gatsby-theme-leasot for convenience.
Alternatively, since v1.2.0, you can bring your own source plugin and set the internalType accordingly.

Usage

{
  resolve: `gatsby-source-filesystem`,
  options: {
    path: __dirname,
    // has to match `sourceInstanceName` field in gatsby-transformer-leasot
    name: `leasot`,
    ignore: [
      // can be customized, it's just what works for me at the moment
      /\.*.*\/(node_modules|\.cache|public|static|dist|\.yarn)\/./,
      /\.*.\.(log|jpe?g|png|gif|ico|json|map|gz|pdf)/,
    ],
  },
},

// without options
`gatsby-transformer-leasot`,

// with options
{
  resolve: `gatsby-transformer-leasot`,
  options: {
    sourceInstanceName: `leasot`,
    // parse `NOTE:` in addition to `TODO:` & `FIXME:`
    customTags: [`NOTE`],
    mode: 'mdx',
  },
},

For mdx to work you have to wrap the value in MDXRenderer provided by gatsby-plugin-mdx

Query

allLeasot(
  sort: { fields: [todo___modifiedTime], order: DESC }
) {
  group(field: todo___tag) {
    fieldValue
    totalCount
    nodes {
      id
      todo {
        tag
        line
        ref
        value
        modifiedTime(formatString: "YYYY-MM-DD H:mm")
        file {
          relativePath
        }
      }
    }
  }
}

Note: The name allLeasot depends on the provided sourceInstanceName in the configs. So when you change it you have to change the name option of gatsby-source-filesystem accordingly, lets say todo then you query for allTodo or todo if you just want a single one.

All config options

name	type	default	description
sourceInstanceName	`string`	"leasot"	Has to match the `name` prop of `gatsby-source-filesystem`.
customTags	`array`	[]	Other tags to look for (besides todos and fixmes). Tags are case-insensitive and are strict matching, i.e PROD tag will match PROD but not PRODUCTS. More in Leasot's Docs
mode	`string`	"text"	Supports one of: `text`, `mdx`, `html`.
truncateLinks	`int`\|`object`	{length: 32,style: "smart"}	Provide `int` to change the length only. `style` can be one of: `smart`, `middle`, `end`.
associateParser	`object`	{}	Associate the filetypes with parsers. This allows adding support for new filetypes. More in Leasot's Docs
customParsers	`object`	{}	Extend the parsers by parserName, for example override the defaultParser or add a new parser. Leasot's Docs
internalType (since v1.2.0)	`string`	"File"	Has to match `node.internal.type`

modifiedTime works only locally as file time will be the same on CI

Provides its own Schema

That means if your sourced files don't contain anything for gatsby-transformer-leasot to parse it won't crash as Gatsby will be prepared. Also congratulations for finishing off all notes, fixmes & todos 🥳
