Contentful Migrate Tool

npm contentful-migration version Build Status Downloads

Manage your Contentful schema by creating incremental scripted changes. This project is based on the ideas exposed in Contentful's CMS as Code article

Scripts are written using Contentful's migration tool syntax. Ex:

module.exports.description = "Create Post model";
 
module.exports.up = migration => {
  const post = migration
    .createContentType("post")
    .name("Post")
    .displayField("title")
    .description("Post model");
 
  post
    .createField("title")
    .name("Title")
    .type("Symbol")
    .required(true)
    .localized(false);
};
 
module.exports.down = migration => {
  migration.deleteContentType("post");
};

This command line tool is designed to keep track of changes of content types individually. It keeps the scripts in a migrations folder in your project. This folder must contain one subfolder for each content type. Ex:

your-project
├── README.md
├── migrations
│   ├── banner
│   │   └── 1513743198536-create-banner.js
│   └── post
│       ├── 1513695986378-create-post.js
│       └── 1513716408272-add-date-field.js
├── package.json

Installation

npm install -g contentful-migrate

Usage

Most of the available commands need a personal access token for accessing the CMA (Contentful Management API). You can pass the token using the --access-token option or setting an environment variable called CONTENTFUL_MANAGEMENT_ACCESS_TOKEN

init

Creates the content type 'Migration' into the designated contentful space. This will be used to keep track of the current state of each managed content type.

  Usage: ctf-migrate init [options]

  Options:

    -t, --access-token [access-token]  CMA token, defaults to your environment variable CONTENTFUL_MANAGEMENT_ACCESS_TOKEN if empty
    -s, --space-id [space-id]          space id to use
    -e, --environment-id [env-id]      id of the environment within the space (default 'master')

If the target space already has been init'd before, it will throw an error:

Content type with id "migration" already exists.

bootstrap

Create your migration files for content models already in your space. It gives you the option to squash any previous migration state. Note: It will delete any existing migration scripts and create a consolidated one for each specified content type.

  Usage: ctf-migrate bootstrap [options]

  Options:

    -t, --access-token [access-token]  CMA token, defaults to your environment variable CONTENTFUL_MANAGEMENT_ACCESS_TOKEN if empty
    -s, --space-id [space-id]          space id to use
    -e, --environment-id [env-id]      id of the environment within the space (default 'master')
    -c, --content-type [content-type]  one or more content type to bootstrap with choice to overwrite migration state
    -a, --all                          apply bootstrap to all with choice to overwrite migration state

Example: executing the command ctf-migrate bootstrap -c post -s <space-id> will create a file where the up command will generate the exact snapshot of the Post content model

create

Creates an empty time stamped file in the content-type's migrations folder.

  Usage: ctf-migrate create <name> [options]

  Options:

    -c, --content-type <content-type>  content type name

Example: executing the command ctf-migrate create create-post-model -c post will create a file named ./migrations/post/1513695986378-create-post.js (the timestamp will vary)

list

Lists all migrations for the given content-types, also indicating whether they were already applied and when.

  Usage: ctf-migrate list [options]

  Options:

    -t, --access-token [access-token]  CMA token, defaults to your environment variable CONTENTFUL_MANAGEMENT_ACCESS_TOKEN if empty
    -s, --space-id [space-id]          space id to use
    -e, --environment-id [env-id]      id of the environment within the space (default 'master')
    -c, --content-type [content-type]  one or more content type names to list
    -a, --all                          lists migrations for all content types

Example:

$ ctf-migrate list -s i2ztmmsocxul -c post banner
Listing post
  [2017-12-19 22:12:58] 1513695986378-create-post.js : Create Post model
  [pending] 1513716408272-add-title-field.js : Adds title field
Listing banner
  [2018-01-08 15:01:45] 20180103165614-create-banner.js : Create Banner model
  [2018-01-22 11:01:33] 20180111172942-add-subtitle-field.js: Add Subtitle field

For the post model in this example, the first script (create-post.js) has already been applied but the second one (add-title-field.js) has not. For the banner model, all scripts have been applied.

up

Migrates up to a specific version or all pending scripts if a filename is not informed. This will apply pending scripts for the specified content-type into the specified space.

  Usage: ctf-migrate up [filename] [options]

  Options:

    -t, --access-token [access-token]  CMA token, defaults to your environment variable CONTENTFUL_MANAGEMENT_ACCESS_TOKEN if empty
    -s, --space-id [space-id]          space id to use
    -e, --environment-id [env-id]      id of the environment within the space (default 'master')
    -c, --content-type [content-type]  one or more content type names to process
    -a, --all                          processes migrations for all content types
    -d, --dry-run                      only shows the plan, don't write anything to contentful. defaults to false

down

ATTENTION: As noted in the CMS as Code article, "in real-world situations there is often no real way to down migrate content without resorting to backups". Even though we agree with that assertion, we still think there is value in having a down function to make it easier to develop and debug the up migration scripts (when you're working on a dev/test space), as it makes it easy to revert your changes and try again, without resorting to any manual intervention.*

Migrates down to a specific version or just the last one if filename is not informed. This will roll back applied scripts for the specified content-type from the specified space.

  Usage: ctf-migrate down [filename] [options]

  Options:

    -t, --access-token [access-token]  CMA token, defaults to your environment variable CONTENTFUL_MANAGEMENT_ACCESS_TOKEN if empty
    -s, --space-id [space-id]          space id to use
    -e, --environment-id [env-id]      id of the environment within the space (default 'master')
    -c, --content-type [content-type]  content type name
    -d, --dry-run                      only shows the plan, don't write anything to contentful. defaults to false
