How to use
Quick start
-
Make sure that you have set up the Github integration on Vercel.
-
Let DatoCMS set everything up for you clicking this button:
Local setup
Once the setup of the project and repo is done, clone the repo locally.
Set up environment variables
In your DatoCMS' project, go to the Settings menu at the top and click API tokens.
Then click Read-only API token and copy the token.
Next, copy the .env.example
file in this directory to .env
(which will be ignored by Git):
cp .env.example .env
Then set each variable on .env
:
NEXT_DATOCMS_API_TOKEN
should be the API token you just copied.NEXT_DATOCMS_PREVIEW_SECRET
can be any random string (but avoid spaces), likeMY_SECRET
- this is used for the Preview Mode](https://www.datocms.com/docs/next-js/setting-up-next-js-preview-mode).
Your .env
file should look like this:
NEXT_DATOCMS_API_TOKEN=...
NEXT_DATOCMS_PREVIEW_SECRET=...
Run your project locally
npm install
npm run dev
Your blog should be up and running on http://localhost:3000!
Try preview mode
On DatoCMS, go to one of the posts you've created and:
- Update the title. For example, you can add
[Draft]
in front of the title. - Click Save, but DO NOT click Publish. By doing this, the post will be in the draft state.
(If it doesn't become draft, you need to go to the model settings for Post
, go to Additional Settings, and turn on Enable draft/published system.)
Now, if you go to the post page on localhost, you won't see the updated title. However, if you use the Preview Mode, you'll be able to see the change (Documentation).
To enable the Preview Mode, go to this URL:
http://localhost:3000/api/draft?secret=<secret>
<secret>
should be the string you entered forNEXT_DATOCMS_PREVIEW_SECRET
.<slug>
should be the post'sslug
attribute (you can check on DatoCMS).
You should now be able to see the updated title. To exit the preview mode, you can click Click here to exit preview mode at the top.
