Gatsby 插件图像 - 图像滑块无法正常加载

Question

我正在尝试使用 Gatsby JS (SSG) 和 framer motion 构建图像滑块。我运行遇到一个问题，即页面上不可见的图像（除了选项卡 1 之外的所有选项卡）没有被预渲染，尽管 GatsbyImage 提供了 loading="eager" 属性。

我已经构建了一个图像提供程序来查询图像滑块中的图像：

const ImageProvider = ({ fileName, alt, imgStyle, style, loading, placeholder }) => {

    const { allImageSharp } = useStaticQuery(graphql`
        {
            allImageSharp {
                nodes {
                    parent {
                        ... on File {
                            base
                        }
                    }
                        gatsbyImageData
                    }
                }
            }
    `)

    const image = allImageSharp.nodes.find(node => node.parent.base === fileName).gatsbyImageData;

    if (!image) return null;

    return (
        <GatsbyImage image={image} alt={alt} imgStyle={imgStyle} style={style} loading={loading} placeholder={placeholder} />
    )
}

export default ImageProvider;

这是图片滑块：

export const TabSlider = ({ 
    tabs,
}) => {
    const [[page, direction], setPage] = useState([0, 0]);

    const elementRef = useRef(null);
    const elementSize = useElementSize(elementRef);

    // We only have 3 images, but we paginate them absolutely (ie 1, 2, 3, 4, 5...) and
    // then wrap that within 0-2 to find our image ID in the array below. By passing an
    // absolute page index as the `motion` component's `key` prop, `AnimatePresence` will
    // detect it as an entirely new image. So you can infinitely paginate as few as 1 images.
    // const imageIndex = wrap(0, images.length, page);

    const paginate = (newDirection) => {
        setPage([page + newDirection, newDirection]);
    };

    return (
        <Container>
            <ImageProvider style={{ width: "100%" }} alt="" loading="eager" placeholder="none" />
            <AnimateSharedLayout>
                <TabsContainer>
                    <TabsHeader>
                        {tabs.map(({ title }, i) => {
                            const isActive = i === page;
                            return (
                                <TabItem
                                    key={i}
                                    className={isActive ? "active-header" : ""}
                                    onClick={() => {
                                        // set page and determine which direction we're going
                                        setPage([i, i - page]);
                                    }}
                                >
                                    <TabHeaderContainer>
                                        <TabHeader>{title}</TabHeader>
                                    </TabHeaderContainer>
                                    {isActive && (
                                        <Underline as={motion.div} layoutId="underline" />
                                    )}
                                </TabItem>
                            );
                        })}
                        <UnderlineBg />
                    </TabsHeader>
                </TabsContainer>
                <ContentContainer>
                    <AnimatePresence initial={false} custom={direction}>
                        <Section
                            as={motion.section}
                            ref={elementRef}
                            key={page}
                            custom={direction}
                            variants={variants}
                            initial="enter"
                            animate="center"
                            exit="exit"
                            transition={{
                                x: { type: "spring", stiffness: 300, damping: 30, duration: 2 },
                                opacity: { duration: 0.2 }
                            }}
                            drag="x"
                            dragConstraints={{ left: 0, right: 0 }}
                            dragElastic={1}
                            onDragEnd={(e, { offset, velocity }) => {
                                const swipe = swipePower(offset.x, velocity.x);

                                if (swipe < -swipeConfidenceThreshold) {
                                    paginate(1);
                                } else if (swipe > swipeConfidenceThreshold) {
                                    paginate(-1);
                                }
                            }}
                        >
                            <Background height={elementSize.height} />
                            <Wrapper>
                                <SlideContainer ref={elementRef}>
                                    <CopywritingContainer>
                                        <H2Header>{tabs[page].header}</H2Header>
                                        <Text>{tabs[page].text}</Text>
                                    </CopywritingContainer>
                                    <ImageContainer>
                                        <ImageProvider fileName={tabs[page].imageFilename} style={{ width: "50%" }} alt="" loading="eager" placeholder="none" />
                                    </ImageContainer>
                                </SlideContainer>
                            </Wrapper>
                        </Section>
                    </AnimatePresence>
                </ContentContainer>
            </AnimateSharedLayout>
        </Container>
    );
};

我看不出哪里出了问题，非常感谢任何指导。

谢谢！

目前似乎无法使用 gatsby-plugin-image。通过使用传统的 HTML 图片标签实现。
