next.js

问题 I have a project with dynamic route like /[category]/[product] . After a client-side request via useRouter to graphql for example /hatchback/nissan/ returns a product with a code of 200, but if I make a request to /hatchback/nissan111/ , I get an error because no such route exists and its response code still of 200 instead of 404. How can I check if a route exists and return a 404 status code during the component mount stage? I use SSR to achive this 来源： https://stackoverflow.com/questions

问题 I'm trying to run the NextJS on a Docker container using Dockerfile and running via docker-compose, after I changed my code in a JS file (such as index.js) the Next server did not reload. But when I've tried to run outside without using Docker (by executing the "npm run dev" command directly) the Next server did reload smoothly. I've also tried to run the server by "nodemon" command (inside a container), it did not make it either. Dockerfile: FROM node:10.14.2-alpine COPY . /home/next_app

However, I am yet to find a way to use the query cursors firebase provides to paginate the data. The building query code is: let postsQuery = firebase.firestore().collection('/posts').orderBy('postedOn', 'asc').limitToLast(10); if (currentTagFilter !== 'All') { postsQuery = postsQuery.where('tag', '==', currentTagFilter); } Now, this works for the first page, but I do not know how to request

问题 I'm using next js. When I try to import M from 'materialize-css'; I get window is undefined . 回答1: You can only import the materialize-css on client side by using dynamic. import dynamic from 'next/dynamic'; const M = dynamic(() => import('materialize-css'), { ssr: false, }); 回答2: I added a useEffect and added this line: if(typeof window !== 'undefined'){ const M = require('materialize-css'); ... } instead of the import statement 来源： https://stackoverflow.com/questions/63292172/window-is

问题 We would like to launch a NextJS 10 app using NGINX so we use a configuration similar to: location /_next/static/ { alias /home/ec2-user/my-app/.next/static/; expires 1y; access_log on; } It works great, it caches for a year our statics but as we use NextJS images I'm failing to add an expires tag on on-the-fly resized images. If I do: location /_next/image/ { alias /home/ec2-user/my-app/.next/image; expires 1y; access_log on; } It just returns a 404 on images. Here is my server part NGINX
