To remap content, export the documents from Prismic using https://prismic.io/docs/import-export#export-tool, and dump them all into ./.dist.
Create a new folder for your new remapping action, and add a ./<ACTION>/remap.js file, where you'll build your filter and remapper.
Remappers should export a filter and map function, both of which take a
{filename: string, doc: PrismicDocument} object.
Once you're ready, run yarn remap --id <ACTION>
This will create two new folders inside ./<ACTION>/: premapped and remapped, containing all the JSON files from .dist/, before and after remapping.
It will also create two new JSON files, before.json and after.json, both containing an array made of all the JSON files from their respective folders.
You'll need to zip remapped and import it in Prismic using their Import tool.
As explained above, the premapped content gets saved into the remapper folder, under premapped.
Just zip that up and upload it to Prismic.
An example process of this could be
- Add new fields
- Write content mappers
- Write parsers for new fields
- PR
- Remap content to new fields and import into Prismic
- Remove old fields
- PR
- Batch sizing (we don't have enough content for this to be an issue).
- Think about version control of content to avoid not being able to roll back.
